Main functions and Characteristics
Transforms the measured signal to a voltage, after HCNR200 linearity photodiode transforms to DC output which has extremely good linear relations with the measured signal, uses the computer aided designed, the principle is simply, circuitry designed concisely, reliability is highly and installment is conveniently.
Operating environment should not have the electric dust and gas of corrosive metal and destruction insulation existence, the altitude should less than 2,500 meters.
The Zero and CAL have been adjusted when products left factory. Please don't adjust at will.
