P-9710-2 Optometer
P-9710-4 Optometer

The P-9710-2 and P-9710-4 optometers are highly efficient single-channel instruments designed for multipurpose use in most photometric and radiometric applications. They offer equivalent features as the model P-9710-1 but with amplifier configuration optimized with gain range independent rise time for the measurement of short light flashes by the pulse stretching method. The P-9710-4 provides an additional trigger input for external triggering by the flash light source. Both meters are compact in size with high-level technical and functional features characterizing the P-9710 as both a laboratory grade instrument and field service meter. A unique feature of the P-9710 is its detector head calibration data connector which stores all data pertaining to a light detector head including model and serial number and calibration data. When plugged into the meter, this data is automatically transmitted and the light meter is ready to go. This feature to use the P-9710-1 optometer with an unlimited range of light detectors is combined with more than sixteen functional measurement modes enabling the user to specify light sources in different ways. The P-9710’s wide signal range of 0.1pA to 2mA with eight manually or automatically selected gain ranges covers the dynamic range of most current semiconductor photodiodes used in light detector heads. The maximum error within this wide dynamic range is 0.2 % through traceable calibrations of each range. The P-9710-1 offers a fast sampling rate ADC combined with an adjustable integration time of up to 6 seconds formed by the average of multiple measurements with 100µs integration time. This averaging feature supports fast data logger measurements used in peak-to-peak, short pulse energy measurements and other modes. A bi-directional RS232 serial interface allows external remote control. Optional PC software is available. The meter is battery (rechargeable) or AC operated.
