Why does my OPHIR vega Measuring Instruments show zero reading?
If your OPHIR Measuring Instruments display shows a zero reading in both power and energy modes, you should check the connections between the sensor and the instrument. Also, verify that the sensor disc is operative by checking the resistance between pins 1 and 9 of the sensor connector, which should be around 11k. If the sensor is defective, there will be an open or short circuit.
What to do if OPHIR vega does not return to zero?
If your OPHIR Measuring Instruments does not return completely to zero on power measurement, and if the sensor is very hot, allow it to cool. Disconnect the sensor from the instrument. If the readout unit still doesn't zero, follow instructions in section 3.5.5. If the offset persists, try zeroing with the sensor connected as well, as described in the same section.
What to do if OPHIR vega Measuring Instruments only works with charger?
If your OPHIR Measuring Instruments works only when connected to the charger, but not with the battery alone, the battery might be low. Recharge it overnight (7-8 hours) with the device turned off. If it still doesn't work, the NiMH battery is likely dead and needs replacement.
Why OPHIR vega shows frequency which is too high?
If your OPHIR Measuring Instruments shows a frequency that is too high, try keeping the cable away from the bench and moving the sensor/display further away from any EMI (electromagnetic interference) sources.
Why does my OPHIR vega Measuring Instruments trigger without laser pulses?
If your OPHIR Measuring Instruments triggers even without exposure to laser pulses, ensure the sensor is mounted to the stand using the insulated plastic rod provided, and not a metal rod.
