Note: When using a 25 mm Astral calororimeter for measuring average power levels below 30 mW and single pulse energy levels below 30 mJ, a Scientech Model 36-0203A, Isoperibol Enclosure, is required. The isoperibol enclosure should not be used at average power levels above 30 mW, and single pulse energy levels above 100 mJ because unwanted heat build up will occur.
S310 Rear Panel S310 Front Panel Turn On Sequence The S310 cycles through a self-calibration sequence whenever it is turned on. The display will show all segments until completion of the self-calibration period which takes about 25 seconds. At the end of this sequence the unit will revert to its operational state in its last used configuration.
operational state and implements any changes to the group configuration made up to this point. There are four setup groups which can be configured and recalled by pressing the SETUP button. To choose one of four setup groups press the SETUP button. The setup group last used (1, 2, 3, or 4) will appear in the display.
7. 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.
displayed value of the S310 power reading the same as the NIST standard. Press the SELECT button when the readings match. 6. The "At" (attenuation) annunciator now appears in the display. If no attenuator or correction factor is to be applied to the displayed value, the setting should be 1.000. If a multiplier is to be applied to the displayed value, use the count up (RANGE), count down (MODE) buttons to enter the multiplier value.

5. 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. 6.
Range The RANGE button is used to select the range most appropriate for the power or energy level to be measured. On the S310 only, held down the RANGE button to toggle the analog meter on or off. The appropriate ranges will be automatically determined by the type of detector which has been programmed into the group which has been selected.
4. The STATS button must be pressed to recall each data point: the number of pulses collected, the average energy (AVG), minimum energy (MIN), maximum energy (MAX), standard deviation (SIGMA), and coefficient of variation (CV%). After recalling the data, the flashing STATS annunciator indicates the S310 is ready for a new run.
PERATING ROCEDURES P S310 SING THE WITH ECTOR YROELECTRIC ETECTORS 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. Models PHF25, PHF50, SPHF25, SPHF50, PHF02, PHF05, and PHF09 have a partially absorbing, partially reflecting chromium coating.
Average Energy Mode The average energy mode displays a running average of a selected number of pulses from 2 to 9999. Enter into the average energy mode by pressing the MODE button until the “J AVG” annunciator appears in the display.
Viable external triggers: The following pulses will not trigger the S310: A laser pulse must be delivered 1 to 3 msec. (depending on the detector type) after an external trigger occurs or the meter will reset. Pyroelectric Detector Operation With Oscilloscope The pyroelectric detectors may be connected directly to a 1 MΩ...
Battery Installation Do not touch the delicate pyroelectric crystals in the HR Series detectors. They should only be cleaned with a stream of clean air; nitrogen or CO 2 . Set Electrical Time Constants for Model PHF02, PHF05 and PHF09 The range 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):...
the SELECT button or simply wait a few seconds and the energy mode will automatically be selected. The system is now ready to measure the energy level of individual pulses. With the calorimeter delay entered, the S310 will display the "trig" annunciator and the single pulse energy after the first pulse is delivered.
Again, this can be determined by noting the peak voltage value on the analog output, and the joules reading on the S310 display. With a pyroelectric detector connected to the S310, determine the relationship between the peak voltage 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: 1.
Page 24
Calorimeters 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: = peak voltage from the analog output = the calorimeter time constant from the calorimeter serial tag = the calorimeter output sensitivity as follows:...
Page 25
The analog output voltage is approximately 3 volts full scale. With an Ultra calorimeter the digital display will read up to 300 watts, even though the Ultra Calorimeter is only rated for 150 watts. To calculate power from the analog output voltage use the following equation. [0.0332(S)] - [3 x 10 V = analog output voltage (V) S = Ultra sensitivity mV/W...
Compare this resistance to R c in the calibration data in the front of the manual. The two should agree within 2%. If not contact Scientech. 5. Remove the DVM. Connect a power supply to the SUB and HTR test points and connect the DVM to monitor the power supply.
2. Select the DC volts mode. 3. Direct the laser beam on to the absorbing surface of the calorimeter. 4. When the display of the DVM has stabilized (about 2 minutes), calculate the laser power using the formula: W = V/S where: W = Laser power in watts V = Voltage reading of the DVM in volts...

1. 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: E = ∑ W xdt = (dt/S)∑ V The error caused by this procedure is: dE = (dt/S) Σ...
Damage Considerations 1. Surface Absorbers Surface absorbing calorimeters have been found to safely withstand 200 W/cm 2 . This heat input is diffused across the thermopile surface so that the local surface temperature is acceptable. Experience has indicated the damage threshold for a single pulse to be 1 joule/cm 2 in a 1 microsecond gaussian pulse. For the recommended operatings limits please review the energy density formulas given in the chart on page 1.

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. 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.

*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. This command halts RPT?, SND?, or COL? commands in progress. It also terminates statistics gathering started by the COL command.
