The P-9710-1 Optometer in combination with one or more Gigahertz-Optik photometric light detectors forms a universal photometer for demanding light measurement applications. Its compact size and high-level technical and functional features characterize the P-9710-1 as both laboratory grade instrument and field service meter. A unique feature of the P-9710-1 is its detector head calibration data connector which stores all data pertaining to the 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. The ability to use the P-9710-1 optometer with an unlimited range of light detectors in combination with more than sixteen functional measurement modes enables the user to specify light sources in many 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 sample rate ADC combined with a adjustable integration time of up to 6 seconds formed by the average of multiple measurements with 100µs integration time. This averaging feature support fast data logger measurements used in peak-peak, short pulse energy measurements and others. A bi-directional RS232 serial interface allows external remote control. A PC software is offered. The meter is battery (rechargeable) or AC operated.
