To review, change, or setup a Group Setting for Vector calorimeters, proceed as follows:

A. Press the SETUP button. The Group Setting last used will appear in the display.

B. To move to the next Group, press SETUP button again.

C. To select a Group, press the SELECT button when the Group you desire appears in the display

(failure to press the SELECT button within 3 seconds will activate the Group shown in the d isplay and return the S310 to its operational state).

D. Press the SETUP button until the calorimeter annunciator “CAL” appears in the display . Press the

SELECT button to activate the calorimeter configuration program.

E. The "tc" (time constant) annunciator now appears in the display. The time constant is a measure

of the length of time the calorimeter takes to respond to a laser beam.

Press the count up (RANGE) and count down (MODE) buttons to change the number in the display to match the time constant number listed on the serial tag of your Vector calorim eter or int erface module for large aperture calorimeters. Press the SELECT button to enter the time constant value to memory.

F. The "SP" (speed) annunciator now appears in the display. The speed setting allows you to control

the power met er’s display rate. The best value will cause a slight overshoot then a quick settling on the final value. Too high of a setting will cause the display to overshoot then slowly drift back down to the final value. A slow setting will cause the display to slowly count up to the final value.

Press the count up (RANGE) button to speed up or count down (MODE) button to slow down the response time of the meter. Press the SELECT button when the desired number appears in the display. The following settings can be fine tuned to your preference of speed versus overshoot. We recommend these initial settings:

AC2500, AC25HD, ACX25HD 103.0 AC2501, ACX2501, AC25UV, AC2504, AC25FX, ACX25FX 136.0 AC5000, AC50HD ACX50HD, AC50FX, ACX50FX 100.0 AC5001, ACX5001, AC50UV, AC5004, 120.0 360401 with interface module 150.0 380401, 380402, 384UV5 with interface module 245.0 360801 with interface module 170.0 380801, 380802, 388UV5 with interface module 280.0

G. The "Cd" (calorimeter delay) annunciator now appears in the display. The calorimeter delay

feature prohibits the display of energy if a pulse is fired before the entered time (1 to 255 seconds) elapses. The calorimeter must reach environmental thermal equilibrium before a subsequent pulse is fired or low energy measurements will occur.

PN10190T

To set the time delay between pulses use the count up (RANGE) and count down buttons (MODE) buttons to enter the time in seconds. Press the SELECT button after the time has been entered to save the setting. The following time delays are recommended:

AC2500, AC25FX, ACX25FX, AC25HD, ACX25HD 60 seconds AC2501, AC25UV, AC2504 60 seconds AC5000, AC50FX, ACX50FX, AC50HD, ACX50HD 90 seconds AC5001, AC50UV, AC5004 90 seconds 360401 with interface module 105 seconds 380401, 380402, 384UV5 with interface module 180 seconds 360801 with interface module 125 seconds 380801, 380802, 388UV5 with interface module 200 seconds

H. The "At" (attenuation) annunciator now appears in the display. If no attenuator is b eing used in

conjunction with the calorimeter, the attenuation factor in the display must be set at 1.000 since this value is a display multiplier. Attenuation multipliers from .0001 to 9999 can be entered into the displayed value.

The attenuation factors of optics can be entered into the S310 so the displayed value will automatically compensate for the amount of attenuation. For example, assume a beam splitter is being used that transmits 75% and reflects 25% of the beam. If the S310 is set up to measure the reflected beam the attenuation could be set up as follows:

• An attenuation factor of 1 would display the value of the reflected beam.

• An attenuation factor of 3 would display the value of the transmitted beam.

• An attenuation factor of 4 would display the value of the source.

Use the count up (RANGE), count down (MODE) buttons to change the attenuation factor. Press the SELECT button to enter the attenuation factor to memory.

I. If the S310 has the optional IEEE488 interface, the REMOTE annunciator will appear along with

the digital interface previously selected; r232 (RS232) or IEEE (IEEE488). Press the SETUP button to toggle the interface between r232 (RS232) and IEEE (IEEE488). Press the SELECT button when the desired interface appears in the display.

J. If the optional IEEE488 interface was not installed, the "br" (baud rate) annunciator for setting up

the RS232 interface appears in the display along with the baud rate previously selected. To change the baud rate press SETUP button until the desired baud rate appears in the display. One of the following baud rates can be selected: 300, 1200, 2400, 9600, and 19,200. When the preferred baud rate appears in the display press the SELECT button.

K. The "PA" (parity) annunciator now appears in the display. Press the SETUP button to select none,

even, or odd parity. Press the SELECT button to enter the parity of choice to memory

PN10190T

Page 12

L. The "HS" (handshake) annunciator now appears in the display. Press the SETUP button until your

choice of none (nOnE), on/off (onoF), or clear to send (CtS) appears in the display. Press the SELECT button when your choice is displayed to enter the handshake to memory.

M. If IEEE488 has been selected, the "bA" (bus address) annunciator appears with the default bus

address. Bus addresses from 0 to 30 may be selected by pressing the count up (RANGE) count down (MODE) buttons followed by the SELECT button. Once the remote interface has been setup, the group annunciator will appear. Press the SELECT button or simply wait a few seconds and the group will automatically be selected for operation.

Group Settings for Vector Pyroelectric Detectors

Note: The factory default Group for Vector Pyroelectric Detectors is Group #2.

Note: The factory default Group for Vector HR Pyroelectric Detectors is Group #3.

Note: Pressing the CANCEL button at any time during this process will terminate this process with no

changes made.

Note: Holding down the SELECT button for 3 seconds at any time during this process will save any changes made up to that point and return the S310 to its operational state for the Group selected.

Note: If you want to use the transfer calibration function, y ou must select the watts mode prior to entering the Group configuration program.

To review, change, or setup a Group Setting for Vector Pyroelectric or Vector HR Pyroelectric detectors, proceed as follows:

A. Press the SETUP button. The Group Setting last used will appear in the display.

B. To move to the next Group, press SETUP button again. C. To select a Group, press the SELECT button when the Group you desire appears in the display

(failure to press the SELECT button within 3 seconds will activate the Group shown in the display and return the S310 to its operational state).

D. Press the SETUP button until the "PYro" annunciator appears. Immediately press the SELECT

button to select the pyroelectric detector configuration program.

E. Either the "V/J" annunciator or the "V/mJ" annunciator and a detector sensitivity number will

appear in the display. V/J is used for standard p yroelectric detectors. V/mJ is used only for HR pyroelectric detectors. Press the SETUP button to toggle between the V/J and V/ mJ entries . The output sensitivity of the pyroelectric detector in V/J or V/mJ is listed on the serial tag of your detector. Use the count up (RANGE) and count down (MODE) buttons to enter the V/J or V/mJ value. Press the SELECT button to enter the value to memory. Do not push the SELECT button

PN10190T

Page 13

before entering the sensitivity number as this takes you to the next setup step without the proper sensitivity number.

F. The "SP" (speed) annunciator now appears in the display. Press the SETUP button to toggle

between bL (black or HD coated detectors) or hF (high frequency) detector. If the detector Model No. includes the letters “HF”, press the SELECT button when the hF annunciator appears in the display. If the detector’s surface is black (does not have the let ters “ HF” in the Model No.) press the SELECT button when the "bL" annunciator appears in the display.

G. The "AUTO, SET CAL" annunciators now appear in the display (only if watts mode was selected

prior to group configuration). This is the Transfer Calibration function. The Transfer Calibration function is designed to transfer the calibration from a NIST certified calorimeter to a Vector pyroelectric detector. This function allows you to adjust the output sensitivit y o f your Vector pyroelectric detector in combination with your S310 meter (in the average power mode) in order to match the avera ge po wer r eadin g of a N IST c erti fied s ystem. T ypicall y, a 50/50 beam splitter is used with the Vector pyroelectric detector to be calibrated in one beam path and the NIST certified calorimeter in the other beam path. You are to adjust the output sensitivity of the pyroelectric detector while it is operating by using the count up (RANGE), count down (MODE) buttons, which change the V/J or V/mJ settings, to make the displayed value of the S310 power reading the same as the NIST standard. Press the SELECT button when the readings match.

H. The "At" (attenuation) annunciator now appears in the display. This allows you to enter a value

from 0.0001 to 9999 which will become a multiplier of the actual displayed value. I f no attenuator or correction factor is to be used in conjunction with the pyroelectric detector then the attenuation factor must be set to 1.000.

The attenuation factors of optics can be entered into the S310 so the displayed value will automatically com pensat e for the amou nt of atten uatio n. For exam ple, assu me a beam spl itter is being used that transmits 75% and reflects 25% of the beam. If the S310 is set up to measure the reflected beam the attenuation could be set up as follows:

• An attenuation factor of 1 would display the value of the reflected beam.

• An attenuation factor of 3 would display the value of the transmitted beam.

• An attenuation factor of 4 would display the value of the source.

Use the count up (RANGE), count down (MODE) buttons to enter the attenuation value. Press the SELECT button to enter the value to memory.

I. The REMOTE annunciator now appears along with the digital interface previously selected; r232

(RS232) or IEEE (IEEE488). Press the SETUP button to change the interface between r232 (RS232) and IEEE (IEEE488). Press the SELECT button when the desired interface appears in the display.

J. If RS232 has been selected, the "br" (baud rate) annunciator appears in the display along with the

baud rate previously selected. To change the baud rate press the SETUP button repeatedly until the desired baud rate appears in the display. One of the following baud rates can be selected: 300,

PN10190T

Page 14

1200, 2400, 9600, and 19,200. When the preferred baud rate appears in the display press the SELECT button.

K. The "PA" (parity) annunciator now appears in the display. Press the SETUP button to select none,

even, or odd parity. Press the SELECT button to enter the parity choice to memory

L. The "HS" (handshake) annunciator now appears in the display. Press the SETUP button until your

choice of none (nOnE), on/off (onoF), or clear to send (CtS) appears in the display. Press the SELECT button when your choice is displayed to enter the handshake to memory.

OPERATING PROCEDURES

Using the S310 with V ec tor Pyroelectric Detectors

Pyroelectric detector models P25, P50, SP25, SP50, P05, and P09 are coated with a special black absorbing material which provides a very flat spectral response over a broad wavelength band. Pyroelectric detector models PHD25, PHDX25, PHDX25UV, PHD50, PHDX50, PHDX50UV, SPHD25, and SPHD50 are coated with a special high damage absorbing material which provides absorption over a broad wavelength band. Models PHF25, PHF50, SPHF25, SPHF50, PHF02, PHF05, and PHF09 have a partially absorbing, partially reflecting chromium coating. The relative spectral responses of these detectors are shown in the following graph. Please be aware of the absorption differences between the detector’s calibration wavelength and your operational wavelength. Detailed absorption information is contained in the charts at the end of this manual.

(count down) buttons. When the desired number of pulses to be averaged appears in the display, press the SELECT button.

iv. The average energy of the number of pulses you selected will be displayed after the number of

pulses entered in step ii is received by the pyroelectric detector. This is not a running average, but is the average for the pulse population selected in step ii. Nothing is displayed until the full pulse population is delivered. This average is displayed until another full population of pulses is delivered at which time the display is updated with the average for that population of pulses.

C. To Measure Average Power (W AVG)

Note: The maximum re petition rate for average power is 300Hz. The minimum repe tition rate for average

power is 10Hz.

Note: The average power mode displays the average power (watts) of repetitively pulsed lasers. Pyroelectric detectors will not work with continuous wave lasers.

i. Press the MODE button repeatedly until the “W AVG” annunciator appears.

ii. Press the SELECT button (or wait 3 se conds) and the S310 will automatically enter into its

operational state in the average power mode.

8. To Measure a Statistical Run of Energy Pulses

PN10190T

Page 19

Note: Do not use AUTO range when making a statistical run.

Note: Do not go from the Average Power Mode to Stats since the range will be too high. Select the range

manually.

Note: When using the PHF09 pyroelectric detector in the long pulse setting, a manual range must be selected when running statistics.

Note: Each time a new stats run begins, data from the previous run is lost. If statistical data is to be saved, it must be done though the digital interface.

Note: To exit the statistical mode at any time, press the CANCEL button.

Note: Statistics mode can collect data at repetition rates of up to 750 Hz depe nding on the detector model.

The statistics mode will collect data on a pulse population of up to 1000 pulses. At your prompting, the power meter will display the number of pulses deli vered, average energy, minimum energy, maximum energy, standard deviation, and coefficient of variation. When the statistics mode is selected, the energy mode is automati cally activated regardless of t he m od e prev io us l y sele cted. Select the appropri at e r ange for the pulse energy level to be measur ed. It is very importan t to select the most appropriate range. I f you have selected a manual range and the laser pulse(s) has overflowed the maximum energy of the range, OF will be displayed when the data is recalled. You should then select a higher range.

To enter into the statistics mode:

A. Press the STATS button. The number of pulses in the last statistics run will appear in the display.

B. Use the RANGE (count up) and MODE (count down) buttons to change the display to the desired

number of pulses to include in the statistics run (up to 1000).

C. Press the SELECT button to enter the pulse population to memory.

D. Press the SELECT button to begin the run. The power meter will automatically stop once the data

has been collected.

B. Press the STATS button to recall the data to the display. The STATS button must be pressed each

time to recall each of the following statistical calculations:

Number of pulses collected Average energy (AVG) Minimum energy (MIN) Maximum energy (MAX) Standard deviation (SIGMA) Coefficient of variation (CV%)

PN10190T

Page 20

F. After recalling the statistic al inf or mation , the fla shing STA TS a nnunc ia tor indica tes that th e S310

is ready for a new run.

A. Press the SELECT button to start a new run (each time a new run begins, data from the previous

run is lost) or press the CANCEL button to return the power meter to the mode of operation in effect prior to statistics mode.

9. External Trigger

The automatic trigger threshold of the S310 is 7 % of full scale. The external trigger function is designed for single pulse energ y measurement with a calorimeter. It does not improve the trigger circuit of the S310 with pyroelectric detectors.

To Perform a Transfer Calibration

You can transfer a calibration from a calori meter to a Vector pyroelect ric detector using the Tran sfer Calibration function of the S310. To do this, please refer to the Group Settings for Vector Pyroelectric Detectors, parag raph #G. You must follow the Group Settings steps to get into the Transfer Calibration function. This function allows you to adjust the output sensitivity of your Vector pyroelectric detector in combination with your S310 meter in order to match the average power reading from the S310 to that of a NIST certified system. Typically, a 50/50 beam splitter is used with the Vector pyroelectric detector to be calibrated in one beam path and the NIST certified calorimeter in the other beam path.

HR Battery Installation

A 9 Volt alkaline battery comes installed with all HR Series detect ors. Alwa ys select the OFF positi on of the power switch when the detector is not in use to spare the lifetime of the battery. Repla ce the battery when the low battery LED indicator lights up.

Figure 4. HR Detector Battery Access

PN10190T

Page 21

Refer to Figure 4. Remove the two slotted 4-40 binder head screws located on the underside of the detector. Pull off the outer housing to expose the battery. Remove the used battery from the battery holder and snap in the new battery. Slide the outer housing back in to place and secure with the screws.

Do not touch the delicate pyroelectric crystals in the HR Series detectors. The y should only be cleaned with a stream of clean air, nitrogen or CO2.

Set Electrical Time Constants for Model PHF02, PHF05 and PHF09

The pulse width switch, located on the rear of the PHF02, PHF05, and PHF09 detectors, selects one of three electrical time constants and should be set as follows:

S (Short Pulses): Select for pulse durations of 5 µsec. or less. Repetition rates up to 4

kHz can be measured.

I (Intermediate Pulses): Select for pulse durations of 50 µsec. or less. Repetition rates of up to

400 Hz can be measured.

L (Long Pulses): Select for pulse durations of 250 µsec. or less. Repetition rates of up to

80 Hz can be measured.

There are no pulse width settings on the P05 and P09 detectors which utilize a highly absorbing material on the crystal. The pulse duration considerations merely function in the determination of damage thresholds. Repetition rates up to 100 Hz using the P05 and 50 Hz using the P09 can be measured.

Correcting Pyroelectric Detector Operating Parameter s for Use at Different Wavelengths

Due to variability in the manufacturing process the absorption characteristics of the HD and P model detectors can vary in the UV region (190 to 400nm). Scientech r ecommends optica l calibra tion at 266nm if the detector is to be used in the UV region instead of re lying on an absorption ra te in the chart at the end of this manual.

All pyroelectric d etectors are cal ibrated at a spec ific wavelength and the detector’s output sensitivity is derived for that wavelength. The output sensitivity and calibration wavelength is recorded in the Operating Parameters section at the front of the manual and on the detector’s serial tag. When a pyroelectric det ector is used at a wavelength other than the calibration wavelength, its output sensitivity can be adjusted to compensate for the absorption rate at the new wavelength. The new output sensitivity is calculated as follows:

1. Find the absorption rate from the chart at the end of this manual for the calibration wavelength of

your pyroelectric detector.

2. Find the absorption rate for the wavelength where you will be working. PN10190T

Page 22

3. Determine the new output sensitivity using the following formula:

absorption rate of new wavelength x output sensitivity (V/J) = output sensitivity for new

absorpt ion rate of calibration wavelength wavelength from serial tag

This new output sensitivity can be entered into the S310 as described in Group Settings or when using the pyroelectric detector without a S310 power meter as discussed later in this manual.

Using S310 with Vector Series Calorimeters

The calorimeter sele cted needs to be t he appropriate mod el for the planned l aser measurements. Please familiarize yourself with the operating specifications which are given in the front of this manual.

The default Group Setting for calorimeters is Group #1. Either select Group #1 or configure another Group for calorimeters and select that Group.

Vector™ calorimeters are sensitive to all types of thermal input. Due to the handling of the calorimet er during setup and possible environmental temperature differences, thermal gradients may exist in the calorimeter. Allow the calorimeter to sit undisturbed for several minutes to, reach thermal equilibrium, before using.

Note: When using a 25mm calorimeter for measuring average power levels below 30mW and single pulse energy levels below 30mJ, a Scientech Model 360203A isoperibol™ Enclosure is highly recommended. The isoper ibol enclosure should not be used at average power levels above 30mW, and single pulse energy levels above 100mJ because heat build-up will occur.

Note: Large Ap erture calorimet ers and the Interface M odul es that th ey are c alibrat ed with a re matched sets and must be used together.

1. To Turn-On the Meter

Note: For the most accurate measurements possible, the S310 should be turned on and warmed up for 30

minutes.

Press the ON switch located in the rear pan el of the meter. T he S310 will imm ediately turn on with its operational state based on the last used detector Group Setting. If you purchased the S310 with one detector, this detector’s Group settings will be active and you are ready to take measurements. If you purchased more than one detector with the S310, you must choose the Group setting for the detector you are connecting to the S310 as described in step 4. The Group Setting for each detector purchased with your S310 is shown in the Group Setting section.

2. To Turn the Analog Needle On or Off (does not apply to the S310D)

To turn the analog meter on or off, press and keep holding the RANGE button down. Then release after the meter appears or disappears.

Refer to the drawing of the S310 rear panel in Figure 1. A 3 meter mini-DIN type cable with "D" shaped connectors comes with Vector c alorimeters. For large aper ture calo rimeters, th e interconnect cables for both the calorimeter and power meter are hardwired to the interface module. One of input connectors on the rear panel of the S310 is labeled "Astral" for the connection of Vector (previously called Astral) calorimeters and including the large aperture (100 & 200mm apertures) calorimeters. Note that the flat side of the DIN type cables should be oriented up when plugging in to the S310.

5. To Select a Group

A. Press the SETUP button. The Group Setting last used will appear in the display.

B. To move to the next Group, press SETUP button again.

B. To select the appropriate Group, press the SELECT button when the Group you desire appears in

Note: When using PN10748 or PN10769, 10X attenuators, you may want to use an attenuation factor of 10 so the displayed reading on the S310 is correct. However, the range designation may be incorrect if the power or energy reading exceeds the upper limit of the ran ge. See the Group Settings section for details.

7. To Select a Mode

The modes available for the calorimeters are: Average Power (W AVG) or Energy (J).

A. To Measure Average Power (W AVG):

Note: The speed-up circuit (differentiator) in watts mode is controlled by software and was adjusted at the factory to accom modat e the t ype of calorim eter bein g used. You can ch ange the sp eed-up setting to your preference. For changing a Group setting, refer to the Group Setting discussion in the previous section on Group Settings for Vector or Lar ge Aper ture Cal orim eters . The speed-up circuit is not active in AUTO range.

Note: The average power mode displays the average power (watts) of repetitively pulsed lasers or continuous wave lasers.

i. Press the MODE button repeatedly until the “W AVG” annunciator appears.

ii. Press the SELECT button (or simply wait 3 seconds) and the S310 will automatically enter

into its operational state in the average power mode.

iii. Press the CANCEL button to zero the display.

iv. The average power will be displayed.

A. To Measure Energy (J)

Note: Calorimeters can only measure single shot energy pulses (time between pulses is dependent on the calorimeter delay “CD” setting in the Group Setting for calorimeters [see previous section on Group Settings for Vector or Large Aperture Calorimeters]). With the calorimeter delay entered, the S310 will display the "trig" annunciator and the single pulse energy after the first pulse is delivered. The "trig" annunciator will then disappe ar after the calorimeter de lay time has elapsed prompting you to fire another pulse. Do not fire another pulse until the annunciator disappears. If you do, the S310 resets the time delay and ignores the sequential pulse altogether.

i. Press the MODE button (repeatedly, if necessary) until the “J” annunciator appears in the

display.

PN10190T

Page 25

ii. Press the SELECT button (or simply wait 3 seconds) and the joules mode will automatically

be activated.

iii. The energy level of each laser pulse will be displayed on the LCD.

8. To Measure a Statistical Run of Single Shot Energy Pulses

Note: Calorimeters can only measure single shot energy pulses (time between pulses is dependent on the calorimeter delay “CD” setting in the Group Setting for calorimeters [see previous section on Group Settings for Vector or Large Aperture Calorimeters]). With the calorimeter delay entered, the S310 will display the "trig" annunciator and the single pulse energy after the first pulse is delivered. The "trig" annunciator will then disappear after the calorimeter delay time has elapsed prompting you to fire another pulse. Do not fire another pulse until the annunciator disappears. If you do, the S310 resets the time delay and ignores the sequential pulse altogether.

Note: Do not use AUTO range when making a statistical run.

Note: Do not go from the Average Power Mode to Stats since the range will be too high. Select the range

manually.

Note: Each time a new stats run begins, data from the previous run is lost. If statistical data is to be saved, it must be done though the digital interface.

Note: To exit the statistical mode at any time, press the CANCEL button.

The statistics mode will collect data on a pulse population of up to 1000 pulses. At your prompting, the power meter will displ ay the number of pulses delivered, average energy, minimum energy, maximum energy, standard deviation, and coefficient of variation. When the statistics mode is selected, the energy mode is automatically activated regardless of the mode previously selected . S el ect t he ap pro pri ate range for the pulse energy level to be measur ed. It is very importan t to select the most appropriate range. If you have selected a manual range and the laser pulse(s) has overflowed the maximum energy of the range, OF will be displayed when the data is recalled. You should then select a higher range.

To enter into the statistics mode:

A. Press the STATS button. The number of pulses in the last statistics run will appear in the display.

B. Use the RANGE (count up) and MODE (count down) buttons to change the display to the desired

number of pulses to include in the statistics run (up to 1000).

C. Press the SELECT button to enter the pulse population to memory.

D. Press the SELECT button to begin the run. The power meter will automatically stop once the data

has been collected.

E. P ress the STATS button to recall the data to the display. The STATS button must be pressed to

recall each of the following statistical calculations:

PN10190T

Page 26

F. After recalling the statistic al inf or mation , the fla shing STA TS a nnunc ia tor indica tes that th e S310

is ready for a new run.

G. Press the SELECT button to start a new run (each time a new run begins, data from the previous

run is lost) or press the CANCEL button to return the power meter to the mode of operation in effect prior to statistics mode.

9. External Trigger

The external trigger input is located on the rear panel of the S310 as shown in Figure 1. The external trigger function is designed to ensure the entire pulse energy of a single pulse is captured by the S310 power meter. An extern al tri gger “awakens” the S310’s circuitry so that it is ready for the arrival of the laser pulse. The external trigger pulse must have the following characteristics:

1. 2.5 volts min. to 5 volts max.

2. A minimum pulse width of 10 µsec. to a maximum of the laser pulse repetition rate.

3. A maximum rise/fall time of 500 nsec.

4. Delivered 1 to 3 milliseconds prior to the laser pulse.

The trigger is generated on the rising edge of the incoming pulse.

The following are viable external triggers.

The following pulses will not trigger the S310.

Correcting FX Calorimeter Operating Parameters for U se at Different Wavelengths

Note: FX calo ri meters are no long er avai labl e f or sal e. Th is i nformati on i s pro vided fo r users w ho previously purchased FX calorimeters to understand how they operate with Vector power meters.

Note: Due to variability in the manufacturing process the absorption characteristics of th e FX model

detectors can vary in the UV region (190 to 400nm). Scientech r ecommends optica l calibra tion at 266nm if the detector is to be used in the UV region instead of re lying on an absorption ra te in the chart at the end of this manual.

Scientech calorim eters in gene ral have a flat response to al l wavelengths within their sp ecified spectr al response. FX and FXX calorimeters are an exception to that rule and are calibrated at a specific wavelength by adjusting the ca lor imeter’s gain circuitry for that wavelength. The calibration wavelength is recorded in the Operating Parameters section at the front of the manual and on the detector’s serial tag. When a FX or FXX calor im eter i s used at a w avel ength o th er t han t he c al i brat io n wavelength, the power meter’s displayed value can be adj usted to compens ate for t he absorp tion rate at t he new w avelength by using an attenuation factor. The attenuation factor is calculated as follows:

1. Find the absorption rate from the chart at the end of this manual for the calibration wavelength of your

calorimeter.

2. Find the absorption rate for the wavelength where you will be working.

3. Determine the attenuation factor using the following formula:

absorption rate of calibration wavelength = attenuation factor

absorption rate of the new wavelength

The attenuation factor can be entered into the S310 as described in the Group Setting section.

PN10190T

Page 28

Analog Output

The analog output is an uncalibrated output accessible via the 50 ohm terminated BNC connector located on the power meter's r ear panel (see Figure 1). Although the analog output voltage level is uncalibrated, it is representative of the power and energy readings displayed on the S310. The analog output voltage level is approximately 3 volts full scale. For high accuracy, you must determine the relationship between the analog output voltage level and the power and energy readings on the S310 display.

With a calorimeter connected to the S310 in watts mode, the analog output voltage readings will rise to a steady level when power is applied to the calorimeter. After the voltage readings become stable, note the analog output voltage reading and the watt reading on the S310 display. All subsequent voltage readings will have the same V/W value s. In the joules mode, the voltage w ill rise to a peak value relatively quickly (seconds) followed by a rapid return to baseline. The peak voltage is representative of the joules value. Again, this can be determined by noting the peak voltag e value on the analog output, and the joules reading on the S310 display.

With a pyroelectric det ecto r connected t o the S31 0, determi ne the relati onsh ip between t he peak vo ltage value and the energy (joules) or power (watts) reading on the S310 display in the same manner. The analog output with the various detectors and operating modes should appear as follows:

A. Calorimeter Watts Mode

Compare voltage to the watt reading displayed on the S310 to determine V/W constant to use when looking at the analog output.

In power (watts) mode, the analog output is nominally 3 V full scale for each range. Therefore, to calculate watts from the analog output voltage:

W = V/S

where:

V = analog output voltage (V) S = analog output sensitivity (V/W) ≈ 3 V/range (W) (for example, on the 10 mW range, S ≈ 3 V/.010 W = 300 V/W)

B. Calorimeter Joules Mode

PN10190T

Page 29

Compare the peak voltage to the energy (joules) reading displayed on the S310 to determine V/J constant to use when looking at the analog output.

In the energy (joules) mode the analog output is an amplified voltage signal proportional to the voltage generated by the calorimeter thermopile. To calculate energy (joules) from the analog output use the following equation.

J = 0.3(Vpk)(TC)

(S)(R)

where:

Vpk = peak voltage from the analog output

TC = calorimeter time constant from the calorimeter serial tag

S = calorimeter output sensitivity as follows:

0.5 V/W for 25 mm models

0.1667 V/W for 50 mm models and large aperture calorimeters

R = power meter range multiplier as follows:

10.0 for the 10 or 30 range

100.0 for the 1 or 3 range 1,000.0 for the .1 or .3 range 10,000.0 for the .01 or .03 range

C. Pyroelectric Watts and Joules Modes

Compare peak voltage to energy (joules) or power (watts) reading displayed on the S310 to determine V/J or V/W constant to use when looking at the analog output.

W = Vpk/S

where:

Vpk = peak voltage from the analog output

S = analog output sensitivity (V/W) ≈ 3 V/range (W) (for example, on the 3mW range, S ≈ 3 V/.003 W = 1000 V/W)

DETECTOR OPERATION WITHOUT A POWER METER

Pyroelectric D et ector Operation without Power Meter

A. Standard and SP Models

Standard and SP model pyroelectric detectors can be operated with a 1MΩ input oscilloscope. The peak

voltage shown on the oscilloscope can be divided by the V/J output sensitivity of the detector to calculate energy.

B. HR Models

HR pyroelectric detectors can be operated with a 50Ω input oscilloscope. The peak voltage shown on the

oscilloscope can be divided by the V/mJ output sensitivity of the detector to calculate energy.

Vector

Vector (previous called Astral) calorimeters are powered up by the power meter. To use a Vector calorimeter with ou t a S cientech power met er, but with a volt meter or chart recorder, you must app l y + / 8VDC to the mini DIN connector as shown in Figure 7. The voltage output of the calorimeter, from pin 8, should be connected to the positive side of the DVM or chart recorder. All 3 of the grounds should be tied together at the negative side. Pins 2 and 3 are not used.

When large aperture calorimeters are used without an power meter their interface module is not used. The output of the calorimeter is connected directly to the DVM or chart recorder. Large aperture calorimeters do not require any power. The voltage output is on pin 1 of the DIN connector and should be connected to the positive side of the DVM or chart recorder. Ground is on pin 3 and should be connected to the negative side. Pin 2 is not used. Refer to Figure 6.

Note: Whenever a large apertur e calorim eter is used with out a power meter the interface module is not

Calorimeter Response:

The response of a calorimeter to a single pulse input as displayed by a chart recorder appears below.

The output voltage from a chart recorder can be converted to wattage at any time by:

PN10190T

Page 36

W = V/S, Wi = Vi/S V = Chart recorder voltage level in mV S = Calorimeter sensitivity in mV/W

The total energy (E) in the pulse can be found by integrating the instantaneous wattage over time:

∞

E = ∫ W(t) dt

The following methods may be used to compute the total integrated energy:

Numerical Integration:

Finding the area under the curve in figure 7 is the equivalent procedure for determining pulse energy.

Choose an appropriate time interval, dt, and perform the summation:

N N E = ∑ Wixdt = (dt/S)∑ Vi I=1 i=1

The error caused by this procedure is:

N dE = (dt/S) Σ dVi i=1

The error, in theory, is only dependent upon the value of ∑dVi, that is the cumulative random error of Vi. This number should approach zero if data is carefully taken. The accurac y is also increased if the time interval, dt, is minimized. Numerical integration can yield accurate results, but is a tedious task.

Initial Voltage Interpolation:

A method used to eliminate the tedious nume rical i ntegration ta sk is to project the thermal decay envelope on to the voltage axis, determine the 1/e decay time constant T, and estimate the total energy value (E):

E = (Vo/S) x T

The change from thermal absorption to thermal transport phenomena near the peak causes difficulty in accurately projecting the envelope on to the voltage axis introducing an error, dVo. Further, the determination of the time constant T, introduces another error, dT. The total error is the sum of the two errors.

dE = (Vo/S)dT + (T/S)dVo

The difficulty in eliminating the potential error makes this method typically less accurate than numerical integration, but much faster in application.

PN10190T

Page 37

Peak Voltage Estimate:

The peak voltage method requires using an independent determination of total energy and referencing it back to the peak voltage value, Vp.

For a given pulse, use the numerical integration method to obtain E. Note the peak voltage, Vp. Compute the value, F

F = E/Vp

For the next pulse compute the total energy: E = F x Vp

The error in using this method yields: dE = FdVp + VpdF

The accuracy of this measurement depends upon the error in the original calibration, dF, and the error in the peak voltage dVp. A careful numerical integration yields a value for dF near zero. The value of dVp can be minimized by maintaining the geometry of the system (i.e. beam intensity, beam profile, wavelength and environment) during operation to be the same as during calibration. Under controlled circumstances, the peak method accuracy usually falls between the numerical integration and initial voltage interpolation methods.

REMOTE INTERFACE LANGUAGE

The remote interface language for the S310 is compatible with standard IEEE488.2 and it also works with the RS-232 remote interface.

A. RS-232 Connector

The RS-232 connector is a 9 pin subminiature connector on the instrument rear panel. The pin out and pin descriptions are shown below:

Pin 1 Unused Pin 2 Data In (RXD) Pin 3 Data Out (TXD) Pin 4 DTR (is generated) Pin 5 Ground Pin 6 DSR (is ignored) Pin 7 RTS (is marking) Pin 8 CTS (is evaluated if requested) Pin 9 Unused

PN10190T

Page 38

B. RS-232 Specifications

Type: EIA-RS232C Method: Half-duplex, Asynchronous Transmission: Bi-directional Format: 300, 1200, 2400, 9600, 19200 baud rate selectable Data bits: 7 Parity bit: Even, Odd, or None Stop bit: 1 Code: ASCII Total no. of bits: 10

* The start bit counts for the first bit. Therefore, if you choose no parity you must have 2 stop bits.

C. Remote Interface Language Syntax

Remote interface m essages consis t of zero or mor e commands or queries, separated by semicolons and terminated by a linefeed (IEEE488) or a carriage return (RS232). A command or query consists of a command or query header followed by zero or more arguments separated by commas. Messages must be less than 75 characters.

Example:

cmd1 arg1;cmd2arg1,arg2;...cmdN arg1

The queries RPT?, SND?, COL?, and *OPC?, and the commands COL and *OPC are intended to be placed as the last command in the message. Placing them elsewhere will not result in harm to the instrument, but it may produce results which seem unusual.

Queries which have not finished will be aborted by the receipt of additional commands or queries. This will result in Query Errors in the IEEE488 interface. If a RP T?, COL?, or SND? query is immediately followed by another command, it is likely tha t no data will be transmitte d. If COL is followed by another command, statistics gathering will be halted unless the command *WAI appears between the two commands.

D. Remote Interface Language Common Commands and Queries

Most commands and queries may be used with either the RS232 interface or the IEEE488 interface. Some commands, however, work only with the IEEE488 interface. Some commands require that a password has been entered. A few commands are archaic, but were left in because no harm was done, and they may be needed again if multi-channel units are constructed again.

The commands which work in both interfaces are presented first , followed by the password protected commands peculiar to the IEEE488 interface, followed finally by the archaic commands. In the descriptions which follow, the command (or query) will be presented first, followed optionally by one or more arguments, separ ated by commas. When the vertical bar "|" is used i n an argument, it denotes the word "or", and signifies that one and only one of the items separated by bars ma y be inserted into the

PN10190T

Page 39

space of the argument. For example, the command: XXXA|B,C has two arguments, the first of which may be `A' or `B', and the second of which is t he letter `C'. W here a space ch aracter is required by the syntax, it is represented with an underline character.

Commands in this group are available from both interfaces: *IDN?

This query takes no arguments, and returns a comma separated collection of four strings, describing respectively the manufacturer of the instrument (Scientech, Inc.), the model number (S310), the serial number, and the firmware version number.

*SAV_<dec num>

This is the IEEE488.2 common command for saving the instrument setup. The number may be an integer from 1 through 4. When used from either remote interface, it saves the current configuration to the numbered save area. The next time the instrument is powered up or the *RST command is issued with the same save area as the default, or the RCL command is executed for the same save area, the configuration will be restored to the values saved.

SENS_PYRO|CAL|PHR|ULTRA

Sets the detector type.

SENS?

Returns the detector type (PYRO|CAL|PHR|ULTRA).

SND?

The SND? query causes the instrument to send the next reading to the remote interface. When using a calorimeter in the joules mode, the SND? query must be sent to the S310 before the calorimeter is pulsed by the laser.

RPT?

This query causes the remote interface to begin sending a sequence of comma-separated readings. A new reading is sent each time one is taken by the instrument. This activity will continue until the remote interface is interrupted by a new command or query, or the instrument is turned off.

COL _<dec num>

This command causes the instrument in energy mode to begin collecting readings for statistical analysis indicated by the response COLLECTING... This command continues until <dec num> data points are collected, or until it is interrupted by another command. If it is interrupted, no statistics are computed. If it terminates normally, a carriage return and line feed occurs, and it computes values for the mean, max, standard deviation, and coefficient of variation of the data points collected. Those values may then be

RANGE_<dec num>|auto

Sets the range to the decimal number supplied, or to the closest legal range allowed for the current detector and configuration. If the word auto is supplied, this command activates the auto-range feature i f it is supported for the current detector and configuration.

RANGE?

The RANGE query returns the decimal number between 1 and the maximum range of the instrument. The meaning of the number varies, depending upon the type of detector, and the configuration of the instrument. (Generally speaking, there are 5 ranges, though not all of them are used for every detector).

MEAN?

If stat istics have been collected from the front panel, or by the COL or COL? commands, this command returns the mean value of the collection. If no statistics have been collected, it returns to zero.

MIN?

If statistics have been co llected from the fro nt panel, or b y the COL or COL? commands, this command returns the minimum value of the collection. If no statistics have been collected, it returns to zero.

MAX?

If statistics have been collected from the front panel, or by the COL or COL? commands, this command returns the maximum value of the collection. If no statistics have been collected, it returns to zero.

PN10190T

Page 41

SIGMA?

If statistics have been collected from the front panel, or by the COL or COL? commands, this command returns the standard deviation of the collection. If no statistics have been collected it returns zero.

CV?

If statistics have been collected from the front panel, or by the COL or COL? commands, this command returns the coefficient of variation of the collection. If no statistics have been collected it returns zero.

PULSES?

Returns the number of pulses collected in the last run.

DUMP?

If statistics have been collected from the front panel, or by the COL or COL? commands, this command returns all of the data values in the collection. If no statistics have been collected, it does nothing.

BAUD_<dec num>

If the <dec num> takes any of the values 300, 1200, 2400, 9600, or 19200; or any of their abbreviations 3, 12, 24, 96, 192, this command sets the RS232 baud rate to the corresponding value.

PARITY EVEN|ODD|NONE

Sets the parity of the RS232 interface to even parity, odd parity, or no parity, as specified.

HANDS XON|CTS|NONE

Sets the handshake method of the RS232 interface to XON/XOFF,CTS, or NONE as specified.

IO RS232|IEEE

On units with both IEEE and RS232 interfaces, this command makes the named interface the S AVED active interface. The next time the instrument is powered up, or its configuration is restored from the configuration save set active when this command was issued, the specified interface becomes the acti ve remote interface.

*RST

This is the IEEE488.2 common command by the same name. When executed from the RS232 interface, it has the effect of restoring the saved instrument configuration from the current save area. It has the additional function in the IEEE488 interface of forcing the interface into the OCIS state and the OQIS state.

METER ON|OFF

PN10190T

Page 42

Activates or deactivates the analog meter.

MODE VOLTS|ENERGY|AVGE|AVGP

If the specified mode is valid for the detector in use, the software changes mode to the one specified.

MODE?

Returns the instrument's operating mode. The possible responses are VOLTS, ENERGY, AVGE, and AVGP.

*TST?

This is the IEEE488.2 common query. From either interface, it causes ROM checksum, and nondestructive RAM test to be run. If the tests succeed, this query returns zero. If the ROM test fails, a 1 is returned. If the RAM test fails, a 2 is returned.

*OPC?

This is the IEEE488.2 common query. From either interface, it waits until no overlapping command is in progress, and then it returns a 1.

*WAI

This is the IEEE488.2 common command. From either interface, it causes the command processor to wait until any overlapping command is finished before continuing to process commands.

CLR

This command halts RPT?, SND?, or COL? commands in progres s. I t a lso te rmin ate s sta tistics gathering started by the COL command. This command is issued internally whenever a carriage return that is not preceded by a command is typed into the RS232 interface. When the IEEE488 interface receives a linefeed terminated message with no commands, it too generates the CLR command.

*RCL_<dec num>

This is the IEEE488.2 common command. It takes the single numeric argument [1-4], and restores the instrument configuration to that configuration stored in the corresponding save area. It also places the IEEE interface into the OCIS and OQIS states.

COUNT_<dec num>

Sets the number of pulses making up each average in average energy mode.

COUNT?

Returns the number of pulses making up each average in average energy mode.

PN10190T

Page 43
