INTRODUCTION

The HD2102.1 and HD2102.2 are portable instruments with a large LCD display. They measure illumination, luminance, PAR and irradiance (across VIS-NIR, UVA, UVB and UVC spectral

regions or in the measurement of effective irradiance according to the UV action curve).

The probes are fitted with the SICRAM automatic detection module: in addition to detection, the unit of measurement selection is also automatic. The factory calibration settings are already memorized inside the instruments.

In addition to instantaneous measurement the instruments calculate the acquired measurements time integral Q(t). Some thresholds can be associated with the integrated measurement and with the integration time, which can be set in the menu. When exceeded these thresholds cause the instrument to stop the integral calculation.

The HD2102.2 instrument is a datalogger. It memorizes up to 38,000 samples with single probes and 14,000 with combined probes. Data can be transferred from the instrument connected to a PC via the RS232C serial port or USB 2.0 port. The storing interval, printing, and baud rate can be configured using the menu. The HD2102.1 and HD2102.2 models are fitted with an RS232C serial port and can transfer the acquired measurements in real time to a PC or to a portable printer.

The Max, Min and Avg function calculate the maximum, minimum or average values. Other functions include: the relative measurement REL, the HOLD function, and the automatic turning off that can also be disabled.

The instruments have IP66 protection degree.

This manual describes the HD2102.1 and HD2102.2 models: if not otherwise specified, the description is intended to be applicable to both models.

KEYBOARD AND MENU DESCRIPTION

Foreword

The instrument keyboard is composed of single-function keys, like the SERIAL key in the HD2102.1 model, and double-function keys such as the ON-OFF/Auto-OFF key. In the double-keys, the function in the upper part is the “main function”, while the one in the bottom part is the “secondary function”. When the instrument is in standard measurement mode, the main function is active. In the menu or in conjunction with the FUNC key, the secondary function is enabled. The pressing of a key is accompanied by a short confirmation beep: a longer beep sounds if the wrong key is pressed. Each key specific function is described in detail below.

ON-OFF/Auto-OFF key

The instrument is turned on and off using the ON/OFF key. The turning on enables all display segments for a few seconds, starts an auto-test including the detection of the probe connected to the input, and sets the instrument ready for normal measurement.

If during turning on no probes are connected, the message PROB ERR is displayed. When the probe is inserted into a functioning instrument, it is not detected. As the probe's data are captured upon turning the instrument on, it is necessary to turn the instrument off and on again. Replace the probes when the instrument is off.

If a combined probe LP 471 P-A or LP 471 A-UVeff is connected to the instrument, at switching on, the instrument displays alternatively the measures of the two sensors. Pressing any key (excluded ON/OFF key), automatic commutation is turned off. To reactivate it, press HOLD and REL keys together.

Automatic turning off

The instrument has an AutoPowerOff function that automatically turns the instrument off after about 8 minutes if no key is pressed during the intervening time. The AutoPowerOff function can be disabled by holding the HOLD key pressed down during the entire turning on phase: the battery symbol will blink to remind the user that the instrument can only be turned off by pressing the <ON/OFF> key.

HD2102 - 9 - V2.3

The automatic turning off function is disabled when external power is used. On the other hand, it cannot be disabled when the batteries are discharged.

FUNC/ENTER key

During normal measurement this enables the display and logging of the maximum (MAX), minimum (MIN) and average (AVG) value of the measurements captured by the probe connected to the instrument, updating them with the acquisition of new samples. The acquisition frequency is once a second. The MAX, MIN and AVG measurements remain in the memory until the instrument is on, even after exiting the calculation function. To reset the previous values and restart with a new measurement session, press FUNC until the message “FUNC CLR” appears, then use the arrows to select YES and confirm using ENTER.

In the menu, the ENTER key confirms the current parameter and then goes to the next one.

Pressed together with the UNIT-Q/T key, enables the integral Q(t) calculation function. Pressed together with the MENU-Clear Q/T, resets the previous integral Q(t) calculation (please see the description of the UNIT key).

Attention: the data captured using the Record function cannot be transferred to the PC.

HOLD/ key

It increases the current parameter when used in the menu; when used in measurement mode, it freezes the measurement in progress at the current value, the message HOLD appears in the upper side of the display. To return to the standard measurement, press the key again. Upon turning on the instrument, the AutoPowerOff function can be disabled by holding the HOLD key down (please see the ON-OFF key description). During calculation of the integral Q(t), by pressing the key the displayed value is frozen without

suspending the calculation in progress.

UNIT - Q/T key

During measurement and integral Q(t) calculation, it allows selection of the unit of measurement. By repeatedly pressing the UNIT key, the desired unit of measurement can be selected. In the combined probes LP 471 P-A and LP 471 A-UVeff, the key allows to select one of the available measures (in these probes, unit of measurement cannot be changed).

NOTE: The units of measurement are determined according to the probe connected to the input, as reported in the following table:

calculation is stopped. The variable, replaced here using the ### symbols, is the one selected before entering the menu. By pressing the UNIT key, it is possible to select the coefficient 3, 6 and 9 that multiplies the displayed value respectively by 103, 106, 109. The combined probe LP 471 P-A has two integration limits ("INTG LIM 1" and "INTG LIM 2") while the probe LP 471 A-UVeff has three limits.

2. TIME LIMT HOUR: indicates the number of hours for the integration time limit, after

which the integral calculation is stopped.

3. TIME LIMT MIN: indicates the number of minutes for the integration time limit, after

which the integral calculation is stopped.

4. TIME LIMT SEC: indicates the number of seconds for the integration time limit, after

which the integral calculation is stopped.

5. Management of stored data (only HD2102.2): the message “>>>_LOG_DUMP_or_ERAS”

(Transfer data or erase) is scrolled in the comment line. The center figure reports the number of free memory pages (FREE). All memory data are permanently erased by pressing SERIAL/EraseLOG. By pressing LOG/DumpLOG, the data transfer of logged data on the serial port is started: “BAUD-RATE” must have previously been set to the maximum value (please see the menu items described below and the paragraph "STORING AND TRANSFERRING DATA TO A PERSONAL COMPUTER" on page 25).

6. Sleep_Mode_LOG (Automatic turning off during recording) (only HD2102.2): this

function controls the instrument's automatic turning off during logging, occurring between the capture of a sample and the next one. When the interval is lower than 60 seconds, the instrument will always remain on. With intervals greater than or equal to 60 seconds, it is possible to turn off the instrument between loggings: it will turn on at the moment of sampling and will turn off immediately afterwards, thus increasing the battery life. Using the arrows select YES and confirm using ENTER in order to enable the automatic turning off, select NO and confirm to disable it and keep the instrument on continuously. Note: even if Sleep_Mode_LOG=YES is selected, the instrument does not turn off for less than one minute intervals.

7. Print and log interval: sets the interval in seconds between two loggings or data transfers

to the serial port. The interval can be set at 0, 1s, 5s, 10s, 15s, 30s, 60s (1min), 120s (2min), 300s (5min), 600s (10min), 900s (15min), 1200s (20min), 1800s (30min) and 3600s (1hour).

If the value 0 is set, SERIAL works on command: the sending of data to the serial port is performed each time the SERIAL key is pressed. Recording (LOG) is performed with

one second intervals even if the interval is set to 0. With an interval from 1 to 3600s, continuous data transfer is started when the SERIAL key is pressed. To end the recording (LOG) and continuous data transfer operations (SERIAL with an interval greater than 0), press the same key again.

12. MIN (minutes): to set the current minutes. In order to correctly synchronize the minute, it is

possible to reset the seconds by pressing the UNIT key. Use the arrows to set the current minute plus one, and as soon as that minute is reached press UNIT: this synchronizes the time to the second. Press ENTER to go onto the next item.

13. BAUD_RATE: indicates the frequency used for the serial communication with the PC.

Values from 1200 to 38400 baud. Use the arrows to modify this parameter and confirm using ENTER. The communication between instrument and PC (or serial port printer) only works if the instrument and PC baud rates are the same. If the USB connection is used this parameter value is automatically set (please see the details on page 25).

Reset of integral Q(t)

Simultaneous pressure on the FUNC/ENTER and MENU-CLR Q/T keys resets the integral Q(t) and sets the instrument up for the new calculation. Please see the paragraph dedicated to calculation on page 17.

LOG/DumpLOG key - only HD2102.2

In measurement mode, this function starts and stops the logging of a data block to be saved in the instrument's internal memory. The data logging frequency is set in the "Print and log interval" menu parameter. The data logged between a start and subsequent stop represent a block. When the logging function is on, the “ LOG ” indication is on the display, the battery symbol blinks and a beep is issued each time a logging occurs; when using an external power supply the battery symbol does not appear. To end the logging, press LOG.

The HD2102.2 can turn off during logging between one capture and the next: the function is controlled by the Sleep_Mode_LOG parameter. When the logging interval is less than one minute, the logging instrument remains on; with an interval of at least one minute, it turns off between one capture and the next if the parameter Sleep_Mode_LOG=YES.

The variable appearing on the display upon pressing the LOG key is saved: the variable associated with the probe co nnected to the instrument, with its relevant unit of measurement or the integral Q(t). With the combined probes LP 471 P-A and LP 471 A-UVeff each sample in memory contains three measures (illuminance, UVA irradiance and the ratio of the two measurements with the first probe;

Press the MENU key until the “>>>_LOG_DUMP_or_ERAS” item is displayed and then press on the LOG key: the transfer of the data contained in the instrument internal memory via the serial port is started. Please, see the paragraph dedicated to data transfer on page 25.

SERIAL key - only HD2102.1

SERIAL/EraseLOG key - only HD2102.2

In measurement mode, this function starts and stops the data transfer to the RS232C serial output. According to the settings entered in the Print and log interval menu item, a single sample can be printed if Print and log interval=0 or a continuous indefinite printing of the measured data can be set up if Print and log interval=1…3600 s. The printing operation is accompanied by the display of the RS232 symbol and the blinking of the battery symbol; when using an external power supply the battery symbol does not appear. Press SERIAL to end the continuous printing.

The variable appearing on the display upon pressing the SERIAL key is printed: the variable associated with the probe connected to the instrument, with its relevant unit of measurement or the integral Q(t). With the combined probe LP 471 P-A and LP 471 A-UVeff each sample consists of three measures (illuminance, UVA irradiance and the rat io of the two measurements with the first probe; total effective irradiance, the effective irradiance in the range UV-CB and the UVA irradiance with the second probe).

Before starting the printing with SERIAL, set the baud rate. To do so, select the Baud Rate menu item and select the maximum value equal to 38400 baud by using the arrows. Confirm with ENTER. The DeltaLog9 software for PC will automatically set the baud rate value during connection. If you

are using a different program than DeltaLog9, be sure the baud rate is the same for both the instrument and the PC: the communication will only work in this way.

THE PROBES

The instrument works with photometric and radiometric probes of the LP471… series that measure:

• illuminance (LP 471 PHOT),

• irradiance (LP 471 RAD, LP 471 UVA, LP 471 UVB and LP 471 UVC),

• PAR (LP 471 PAR),

• luminance (LP471 LUM 2)

• effective irradiance according to the UV action curve (LP 471 ERY),

• effective irradiance in the spectral range of blue light (LP 471 BLUE),

• illuminance, UVA irradiance and UVA irradiance - illuminance ratio (combined probe

LP 471 P-A - please see note 1),

• total effective irradiance UVA + UV-CB according to the UV weighting curve (combined

probe LP 471 A-UVeff for measuring total effective irradiance in the range 250...400 nm please see note 1),

• global solar irradiance in the spectral range 400…1100 nm with silicon photodiode (LP 471

SILICON PYRA),

• global solar irradiance in the spectral range 300…3000 nm. Probe consisting of a second

class pyranometer LP PYRA 03 and cable with SICRAM module (LP 471 PYRA 03),

• global solar irradiance in the spectral range 300…3000 nm. Probe consisting of a first class

pyranometer LP PYRA 02 and cable with SICRAM module (LP 471 PYRA 02).

Note 1: the combined probes LP 471 P-A and LP 471 A-UVeff work with instruments HD2102.1 and HD2102.2 having firmware version respectively “HD2102.11” and “HD2102.21” and following. On the back of these instruments a label shows version and date of the firmware. To update previous instruments, you can use the "Update firmware" function of DeltaLog9.

All probes, except LUM 2, have an angular response according to cosine law. Upon turning on the instrument automatically detects the probe connected to the input: it is sufficient to connect it. If the instrument is already on, turn it off and back on again in order for the probe to be detected. The unit of measurement is determined according to the probe connected to the input: if a probe has more units of measurement, use the UNIT key to select the desired unit. In the combined probes, UNIT key allows to select one of the available measures (in these probes, unit of measurement cannot be changed).

All probes are calibrated in factory; no calibration is required by the user. In addition to instantaneous measurement the instrument calculates the time integral Q(t) of the acquired measurement. Some thresholds can be associated with the integrated measurement and with the integration time, which can be set in the menu. When exceeded, these thresholds cause the instrument to stop the integral calculation.

The probe is detected during turn on, and this cannot be performed when the instrument is already on, therefore if a probe is connected and the instrument is on, it is necessary to turn it off and on.

HD2102 - 15 - V2.3

COMBINED PROBE LP 471 P-A

LP 471 P-A is a two sensors combined probe with SICRAM module for measuring illuminance (lux) with standard photopic spectral response and irradiance (μW/cm2) in UVA spectral range (315...400 nm, with peak at 365 nm). Moreover probe provides the ratio of UVA irradiance and illuminance in µW/lumen (quantity of interest in the museums field).

Both sensors are equipped with diffuser for the correction according to the cosine law.

At switching on, the instrument displays alternatively the measures of the two sensors. Pressing any key (excluded ON/OFF key), automatic commutation is turned off. To reactivate it, press HOLD and REL keys together.

To select the measure to display, press UNIT key.

COMBINED PROBE LP 471 A-UVEFF

LP 471 A-UVeff is a two sensors combined probe with SICRAM module for measuring total effective irradiance according to the UV weighting curve. Two sensors are used to correctly

measure the total effective irradiance in the range 250...400 nm.

Both sensors are equipped with diffuser for the correction according to the cosine law.

The probe provides the total effective irradiance (“Er” at display), the effective irradiance in the range UV-CB (“BC” at display) and the UVA irradiance (“A” at display).

At switching on, the instrument displays alternatively the measures UVA and UV-CB of the two sensors. Pressing any key (excluded ON/OFF key), automatic commutation is turned off. To reactivate it, press HOLD and REL keys together.

To select the measure to display, press UNIT key.

PROBES LP 471 PYRA 02 AND LP 471 PYRA 03

LP 471 PYRA 02 and LP 471 PYRA 03 probes measure the global solar radiation in the spectral range 300…3000 nm. They are composed of a first class (LP PYRA 02) or a second class (LP PYRA 03) pyranometer and a cable with SICRAM module.

Since calibration data of pyranometer are saved in SICRAM module, the cable cannot be used together with other pyranometers.

The global solar radiation is expressed in W/m2 or in μW/cm2. Measuring range is 0…2000 W/m2.

The module is equipped with a 5 m or 10 m long cable ending with a 4 poles male connector to be inserted in the female connector of the pyranometer.

No user calibration is required.

The SICRAM module is recognized at the instrument switching on, then it’s absolutely necessary to connect the module before turning the instrument on.

HD2102 - 16 - V2.3

PROBE LP 471 SILICON-PYRA

LP 471 Silicon-PYRA measures the global solar radiation using a silicon photodiode in the spectral range 400…1100 nm.

The particular geometry and the diffuser allows the sensor to have a field of view of 180° according to the cosine law.

The probe is suitable for the measurement of natural sunlight. Under overcast skies, or for reflected light measurements the use of a thermopile pyranometer is recommended (LP 471 PYRA 03 or LP 471 PYRA 02).

The measurement of global solar radiation is expressed in W/m2 or in μW/cm2. Measuring range is 0…2000 W/m2.

No user calibration is required.

The SICRAM module is recognized at the instrument switching on, then it’s absolutely necessary to connect the module before turning the instrument on.

HD2102 - 17 - V2.3

Q/TIME INTEGRATION

In addition to instantaneous measurement, the instrument calculates the following summation:

(1) Q(t) = u(t) t,

⋅Δ Δ

t = 1sec

where u(t) is the instantaneous value of the input variable compared to time t. The sampling interval is fixed at 1 second. As soon as either the Q(t) value or the integration time t reach the set limit, the integration is stopped.

Maximum integration time: 100 hours, 00 minutes, 00 seconds Integration interval: 1 second

How to set the limits

To set the integration limit, enter the "INTG LIMT ###S" menu item. Use the arrows to set the desired value. Confirm by pressing ENTER. To set the final integration time, enter the TIME LIMT HOUR, TIME LIMT MIN and TIME LIMT SEC menu items. Use the arrows to set the desired value in hours, minutes and seconds. Confirm each item using ENTER. To cancel the limit, set its value to 0. Combined probe LP 471 P-A has two integration limits, one for illuminance and one for irradiance. The integral calculation of irradiance/illuminance ratio is not provided. LP 471 A-UVeff probe has three integration limits, one for each band.

How to perform an integration measurement

After setting the limits, as illustrated above, exit the menu and return to normal measurement. Simultaneously press FUNC/ENTER and UNIT-Q/T. To start and stop the integral calculation press Start/Stop Q/T. To cancel the previous integration values and reset it, simultaneously press FUNC/ENTER and MENU - CLR Q/T: if an integration is started without pressing the CLR Q/T key, the calculation will continue from the previous values. The integral calculation can be suspended at any moment pressing Start/Stop Q/T: in this status, to resume the integration, press the key again.

If one or more limits have been enabled in the menu, on reaching of the first, the calculation stops. Pressing FUNC/ENTER alternates the display of Q(t) and integration time.

Because the integration process proceeds according to discrete steps, the Q(t) value according to which the integration is stopped could be slightly different than the set limit, but will be equal to the first integration value that exceeds the limit.

Note: for the LP471 LUM 2 luminance probe, the integral calculation is not provided.

HD2102 - 18 - V2.3

3. The sensors and filters should not exceed the temperature limits established with consequent

irreparable degradation of their characteristics.

4. Do not drop the probes: as this could cause irreparable damage.

5. Avoid taking measurements in presence of high frequency sources, microwave ovens or large

magnetic fields; results may not be very reliable.

6. The instrument is water resistant and IP66, but is not watertight and therefore should not be

immersed in water without closing the free connectors using caps. The probe connectors must be fitted with sealing gaskets. Should the instrument fall into the water, check for any water infiltration. Gently handle the instrument in such a way as to prevent any water infiltration from the connectors' side.

LOW BATTERY WARNING AND BATTERY REPLACEMENT

The battery symbol on the display constantly shows the battery charge status. To the extent that batteries have discharged, the symbol "empties". When the charge decreases still further it starts blinking…

In this case, batteries should be replaced as soon as possible. If you continue to use it, the instrument can no longer ensure correct measurement. The memory data are maintained.

If the battery charge level is insufficient, the following message appears when you turn the instrument on:

BATT TOO LOW

CHNG NOW

The instrument issues a long beep and turns off. In this case, replace the batteries in order to turn the instrument back on.

In order to avoid data loss, the logging session is ended, if the HD2102.2 is logging and battery voltage falls below the minimum operating level.

The battery symbol turns off when the external power supply is connected.

To replace the batteries, switch the instrument off and unscrew the battery cover counter clockwise. After replacing the batteries (4x1.5V alkaline batteries - type AA) screw the cover on clockwise.

After replacing the batteries, the date, time, baud rate, type of probe, printing interval, logging parameters must be set again: in order to simplify the operation, on insertion of the new batteries the instrument turns on automatically and requests these parameters in sequence. To go to the next item press ENTER; to return to measurement mode, press MENU.

HD2102 - 22 - V2.3

MALFUNCTIONING UPON TURNING ON AFTER BATTERY REPLACEMENT

After replacing the batteries, the instrument may not restart correctly; in this case, repeat the operation. After disconnecting the batteries, wait a few minutes in order to allow circuit condensers to discharge completely; then reinsert the batteries.

WARNING ABOUT BATTERY USE

• Batteries should be removed when the instrument is not used for an extended time.

• Flat batteries must be replaced immediately.

• Avoid batteries leaking.

• Always use good quality leakproof alkaline batteries. Sometimes on the market, it is

possible to find new batteries with an insufficient charge capacity.

HD2102 - 23 - V2.3

SERIAL INTERFACE AND USB

The HD2102.1 and HD2102.2 instruments are fitted with an electrically isolated RS-232C serial interface; the HD2102.2 also has an USB 2.0 interface. The following serial cables can be used:

• HD2110CSNM: serial connection cable with 8-pole MiniDin connector on one end and

9-pole Sub D connector on the other end;

• C.206: serial connection cable with 8-pole MiniDin connector on one end and USB type A

connector on the other end. With integrated RS232/USB converter;

• CP23: connection cable with Mini-USB type B connector on one end and USB type A

connector on the other end (only for HD2102.2).

The connection via the C.206 cable requires the previous installation of the cable USB drivers. Install the drivers before connecting the C.206 cable to the PC. The connection via the CP23 cable does not require the installation of USB drivers: when connecting the instrument to the PC, the Windows® operating system automatically recognizes the device as an HID device (Human Interface Device) and uses the drivers already included in the operating system.

The instrument response strings end with the sending of the CR command (Carriage Return). The instrument does not send the LF command (Line Feed). Before sending commands to the instrument via the serial port, locking the keyboard to avoid functioning conflicts is recommended: use the P0 command. When complete, restore the keyboard with the P1 command.

HD2102 - 25 - V2.3

STORING AND TRANSFERRING DATA TO A PERSONAL COMPUTER

The HD2102.1 and HD2102.2 instruments can be connected to a personal computer via an RS232C serial port or USB 2.0 port, and exchange data and information through the DeltaLog9 software running in a Windows operating environment. Both models can send in real time input measured values directly to a PC, through the SERIAL function; the HD2102.2 can also store the values measured by using the Logging function (LOG key) in its internal memory. If necessary, the data stored in the memory can be transferred to a PC later.

THE LOGGING FUNCTION - ONLY FOR HD2102.2

The Logging function allows the recording of up to 38,000 samples with single probes and up to 14,000 with combined probes. The time interval between two consecutive measurements can be set from 1 second to 1 hour. The logging starts by pressing the LOG key and ends by pressing the same key again: the data memorized in this way form a continuous block of data.

The variable appearing on the display upon pressing the LOG key is saved: the variable associated with the probe connected to the instrument, with its relevant unit of measurement or the integral Q(t). With the combined probes LP 471 P-A and LP 471 A-UVeff each sample in memory contains three measures (Illuminance, UVA irradiance and the ratio of the two measurements with the first probe; total effective irradiance, the effective irradiance in the range UV-CB and the UVA irradiance with the second probe).

See the description of the menu item on page 11.

If the automatic turning off option between two recordings (menu >> Sleep_Mode_LOG) is enabled, upon pressing the LOG key the instrument logs the first data and turns off. 15 seconds before the next logging instant, it turns on again to capture the new sample, and then turns off.

The data stored in the memory can be transferred to a PC using the DUMP LOG command: press the MENU key until the “LOG_DUMP_or_ERAS” item is displayed and then press on LOG key. During data transfer the display shows the message DUMP; to stop the data transfer press ESC on the instrument or on the PC. If the connection to the PC is made by DeltaLog9, the software itself manages the connection and sends the appropriate commands: there is no need for any intervention on the instrument by the user.

CLEARING THE MEMORY - ONLY FOR HD2102.2

To clear memory use the Erase Log function (press the MENU key until the “LOG_DUMP_or_ERAS” item is displayed and then the SERIAL/EraseLOG key). The instrument starts clearing the internal memory; at the end of the operation, it goes back to normal display.

NOTES:

• Data transfer does not cause the memory to be erased; the operation can be repeated as many

times as required.

• The logged data remain in memory apart from battery charge conditions.

• In order to print the data to a parallel interface printer, you must use a parallel-serial adaptor (not

supplied).

• The direct connection between instrument and printer via a USB connector does not work.

HD2102 - 26 - V2.3

• Some keys are disabled during logging. The following keys work: HOLD, FUNC (Max-Min-

Avg) and SERIAL.

• Pressing the HOLD, REL and FUNC keys has no effect on the logged data if these keys are

pressed after starting the recording, otherwise the following is valid.

• The recording started with the display in HOLD mode proceeds normally with the actual

measured values (that is, not in “HOLD” mode). Only the display is frozen to the values present when the HOLD key was pressed.

• The same is true for the Max-Min-Avg function.

• If the logging is started when the display is in REL mode, the relative values are logged.

• It is possible to activate both the logging (LOG) and direct transfer (SERIAL) functions at the

same time.

THE PRINT FUNCTION

The PRINT function sends the measurements taken in real time by the instrument inputs directly to a PC or a printer. Print data units of measurement are the same as those used on the display. The function is started by pressing SERIAL key. The time interval between two consecutive prints can be set from 1 second to 1 hour (please see the Print and log interval menu item on page 11).

If the print interval is equal to 0, by pressing SERIAL key the single data is sent to the connected device. If the print interval is higher than 0, the data transfer continues until the operator stops it by pressing SERIAL key again.

The PRINT function works with a standard serial communication program (e.g. Hyperterminal) only through the RS232 serial port of the instrument, using the cable HD2110CSNM or the cable C.206.

Connect the HD40.1 printer using cable HD2110CSNM.

NOTES:

• The print out is formatted across 24 columns.

• Some keys are disabled during serial transmission. The following keys work: ON/OFF, HOLD,

FUNC (Max-Min-Avg) and LOG.

• Pressing the HOLD, REL and FUNC keys has no effect on the printed data if these keys are

pressed after starting the printing, otherwise the following is valid.

• The transfer started with the display in HOLD mode proceeds normally with the actual

measured values (that is, not in “HOLD” mode). Only the display is frozen to the values present when the HOLD key was pressed.

• The same is true for the Max-Min-Avg function.

• If the serial transfer is started when the display is in REL mode, the relative values are

transferred.

• It is possible to activate both the logging (LOG) and direct transfer (SERIAL) functions at the

same time.

Relative Spectral Response

The probe LP 471 ERY measures the effective total irradiance (W/m

eff

) according to the UV action curve (CEI EN 60335-2-27). A particular type of photodiode and a combination of special filters bring the spectral response closer to the UV action curve.

CEI EN 60335-2-27 standards establish a maximum allowable dose of 100J/m2 for first-time exposure and an annual dose of 15000J/m2.

The typical spectral response curve of LP 471 ERY is shown in the Figure together with the UV action curve. The good accordance between the two curves enables the instrument to take reliable measurements of different types of lamps (and filters) used at present for tanning devices.

Each probe is individually calibrated at Delta Ohm photo-radiometry laboratory by means of a double monochrome. Calibration is performed at 295 nm through a calibrated reference

photodiode.

Typical response curve

The radiometric probe LP 471 BLUE measures the irradiance (W/m

) in the spectral range of Blue light. The probe consists of a photodiode with an appropriate filter and is provided with a diffuser for correct measurement according to the cosine law. The spectral response curve of the probe allows to measure the effective irradiance for blue light hazard (curve B (λ) according to the standards ACGIH / ICNIRP) in the spectral range from 380nm to 550nm. Optical radiations in this range can produce photochemical retinal injury. Another field of application is the monitoring of the blue light irradiance in the treatment of neonatal jaundice.
