CE Mark Certification

The Astral Series calorimeters listed in this manual have been certified for the European CE mark.

UNPACKING

The meter, calorimeter, and accessories are shipped in custom packing materials. All packing materials
should be saved for future damage free shipments for calibration or repair.

ADAPTER/BATTERY

When using the Scientech supplied AC adapter/charger, the AI310 will operate with or without the
optional battery installed. However, if the battery is installed, it must have a minimum charge of
approximately 1 hour before the AI310 will operate on battery power alone.

The AI310 can be used with the optional rechargeable battery (part number 11640), which provides
approximately 6 hours of usage before requiring recharging. To recharge the batteries, connect the
charger to the power meter and the appropriate electrical outlet. Allow 1 to 3 hours for a full charge.
Whenever the AC adapter is connected to both the AI310 and wall outlet, the battery is being charged.
The AI310 can be powered by battery or wall plug power supply (or USB interface). If the battery is
installed, it is charged whenever wall plug power (or USB power) is present. When running from wall
plug, with optional battery installed, the battery annunciator in the LCD display will be on when the
battery is being charged and off when the battery is fully charged. This annunciator may also be on
when there is no battery installed. When operating on battery power alone, the annunciator will be off.
When the battery approaches its end of charge, the annunciator will flash at a 1Hz rate for about two
minutes. Then the annunciator will flash at a higher rate (2Hz) letting you know that in about another
two minutes the AI310 will cease to function. In this event you should turn the power rocker switch to
the OFF position, plug in the AC adapter, and turn the power rocker switch to ON. The AI310 will start
in the normal way and the battery annunciator should be on indicating that the battery is being charged.

ASTRAL™ SERIES DETECTOR SPECIFICATIONS

This series consists of a handheld meter and a selection of thermal detectors. Astral™ series detectors
all have memory integrated into the detectors, used to store calibration constants as well as other data
such as integration time and date. Plug an Astral™ detector into the meter, and it’s ready for use.
Without storing calibration data with the detector, you will need to manually enter the calibration data
into the detector via the power meter. Also, if you were using multiple detectors with a single meter,
then having calibration data in the detector also prevents errors if somebody forgets to input the
detector’s calibration data into the meter.

5

The Astral Series detectors are available in either surface or volume absorbing models with apertures of
custom sizes or standard 8mm, 16mm, 25mm, 50mm, 100mm, and 200mm aperture models. The surface
absorbing models are ideal for measuring continuous wave lasers while the volume absorbing models
are well suited for pulsed lasers using either the watts mode or single pulse energy mode.

Figure 2. Astral AI310 Power Meter with 25mm Calorimeter

USING AI310 POWER METER WITH ASTRAL CALORIMETER

1. Turn On the Meter Power

Toggle the ON/OFF rocker switch, located on the top of the AI310, to the ON position. The power
meter will immediately turn on with all LCD segments briefly, and then revert to the operational state
last used. The AI310 will check for the presence of the sensor, and if the sensor is absent, the display
will read “nodF” and the AI310 will continue checking every 15 seconds for 2 minutes. If, after the 2
minutes have elapsed, the sensor is still not found, then the AI310 will power itself down to a “sleep”
mode, displaying “SLEP” in the LCD. If a sensor is subsequently plugged into the AI310, you must
push any front panel button to awaken the AI310 and continue in normal operating mode.

If the AI310 is running from battery power, and if no button has been pressed or if power the reading is
below 1% of full-scale for a period of time set by the user (as described in the timeout instructions
below), The AI310 will also power itself down to a “sleep” mode, displaying “SLEP” in the LCD. To

recover from this dormant mode, push any front panel button to awaken the AI310 and continue in
normal operating mode.

The operating parameters of the SERIES S CALORIMETER are automatically loaded into the AI310
through the calorimeter’s intelligent connector. In normal operating mode the AI310 checks for a sensor
every 15 seconds allowing for hot swapping of sensors with no user intervention required.

2. Connect the Calorimeter

A 3-meter cable with an intelligent connector is hard wired to the Astral Calorimeter. Plug the
detector’s cable into the mating connector on the AI310.

Each detector has a 1/2" diameter mounting hole for installing the detector onto a mounting base
assembly. Screw the mounting base post into one of the mounting holes in the body of the calorimeter.
Optional mounting base assemblies are available for purchase from Scientech for mounting the
detector/mounting base assembly to an optical bench.

3. Zero Button

Pressing the ZERO button will zero the display.

4. Zero the Analog Needle (does not apply to the AI310D)

Refer to Figure 3. The black slotted button located just below the display allows screwdriver adjustment
to set the analog needle to zero. The needle adjustment should be adjusted to zero before connecting the
detector.

5. Turn the Analog Needle On or Off (does not apply to the AI310D)

To turn the analog meter on or off, press and keep holding down the RANGE button. Then release the
button after the meter scale appears or disappears. The analog meter scale will follow the selected range.

To access the menu items, Press MODE and ZERO buttons simultaneously. The display will show the
first menu choice. Press the RANGE button to advance to the next menu choice. Press ZERO button to
select the menu choice. Pressing the RANGE button will increment the displayed value and pressing the
MODE button will decrement the displayed value. Menu items that are available are: Attenuation
Factor (ATTN) and Time Out (TO) and MODE (CAL).

A. Attenuation Factors

Access the Menu, as described in step 13, step through menu choices until ATTN is displayed,
then press the ZERO button to select. Use the RANGE button to increment and the MODE
button to decrement the attenuation factor. Pressing the ZERO and MODE buttons
simultaneously will return the value to 1.00 (the factory default). Press ZERO to select the
attenuation factor and return to normal operation. Very large or small attenuator values may
require re-ranging the power meter for proper operation. For example, with an attenuator value
of 10 and you apply 1 Watt of power, the display will indicate 10 Watts and must be in the 10
Watt range.

Values available are:

0.01… 0.99, 1.0,

1.1… 9.9, 10,
11 … 100

B. Time Out

The time out feature conserves battery power by putting the AI310 to sleep if there are no front panel
button pushes, after a selected period of time. To awaken the AI310 once it is in the sleep mode, press
ZERO on the front panel.

To change the time out period, access the Menu, as described in step 13, step through the menu choices
until TO is displayed, then press the ZERO button to select. Use the RANGE button to increment and
the MODE button to decrement the timeout factor. Pressing the ZERO and MODE buttons
simultaneously will return the value to 0 (the factory default). Press ZERO to select the timeout factor
and return to normal operation.

Default value is 0 or OFF.

Values available are:

0, 5, 10, 15 ... 55, 60 (minutes)

11. Pulse Recovery Time

This changes the time period allowed in making single shot energy measurements. Typically, the time it
takes to recover from a pulse is four to six times the calorimeters thermal time constant. The typical time
for each calorimeter size is given below.

To change the time, access the Menu, as described in step 13, step through the menu choices until CTO
is displayed, then press the ZERO button to select. Use the RANGE button to increment and the MODE
button to decrement the time. Pressing the ZERO and MODE buttons simultaneously will return to the
value last stored. Press ZERO to select the timeout factor and return to normal operation.

Values available are:

15 to 405 seconds in 15 second steps

12. Wall Mount Power Supply

Use the wall mount power supply to power the AI310 and charge the optional battery.

13. Optional Meter Mounting System

Scientech offers a sturdy mount system (Part Number MT) consists of a non-slip base with three
moldable feet, ball mounts, and a meter cradle. This system will hold your AI310 about 15cm above an
optical bench or work surface in an upright position. The ball mounts let you reposition your meter to
accommodate any viewing angle you desire. It also allows you to easily remove your meter at the end
of the day for safekeeping.

SCIENTECH CALIBRATION SERVICE

The Astral™ AI310 power meters and calorimeters are calibrated at Scientech’s authorized service
center and the calibration constants were provided with the detector.

Scientech detectors include a NIST traceable calibration certificate, to document that you are getting the
most accurate laser measurement possible.

An optimum calibration of each detector is ensured by Scientech’s highly trained and skilled service
team. Excessive energy or peak power density can damage a detector. Safe operating limits are specified
in the detector specifications. If your calculated energy or peak power conditions exceed those specified
for the model, optical attenuation may be used as a solution.

Electric substitution heater coils are available as an option that allows customer to perform their own
field calibration. These electric heaters are only available for new detector purchases only by adding an
“H” to the end of the detector part number when placing an order.

Scientech recommends that a complete calibration be performed annually to verify system accuracy.
Please visit Scientech’s website at www.scientechinc.com to obtain an RMA (returned material
authorization) number and complete the form noting that you are requesting calibration of your detector.
You may also contact our Product Service Department at [phone] or [phone] or Fax
[phone] or email [e-mail]. Be prepared to provide model number, serial number
along with contact information. to arrange for a NIST traceable, factory calibration. Scientech calibrates
the detector with its power meter for the same price.
