Main technical specifications:
1. Optical energy measuring range: 1-100J, 200J
2. The detector's receiving aperture: 68x68mm
3. Spectral range: 350nm - 2500nm
4. Measurement uncertainty:<+-5%
Usage:
1. Insert the other end of the signal wire BNC provided with the probe to the right two holes of the digital multi-meter (The protrusion is inserted upwards).
2. Turn the measurement gear from OFF to DC 600m.
3. After the display data is stable, press the MAX button, then the multi-meter shows MAX
4.Trigger the light pulse, and the multi-meterdisplays themonotonically rising data After 5 seconds,the display number shows a peak value and is held by the multi-meter.
5. At this point, the value displayed on the multi-meter is the difference between the maximum and the minimum which is the measured energy value(mV corresponds to J).
6. After measuring, press the MAX MIN button for 3 seconds to make the multi-meter out of the state of MAXMIN. Observe the multi-meter data, and repeat 3 to 5 steps to measure again after it stably displays and no longer drops monotonously.
