Received Light Intensity Check - Fuji Electric ZSS-8 Series Instruction Manual

(1) Remove the cap from the probe (BNC socket) of the receiver unit, and connect the probe and the digital
voltmeter using the BNC cable for light axis adjustment.
(2) Read the DC voltage value. The receiver unit emits a voltage about 3 V DC when the light transmit-
tance is 100%.
(3) The voltage value during zero gas is supplied with the calibration cell connected becomes the reference
light intensity for light axis adjustment which is performed after the equipment is attached to a com-
panion flange (Factory-set voltage is described on a nameplate on the covers of the receiver unit,
transmitter unit, and control unit).
Note 1) CO + O analyzer has BNC sockets for each of CO and O

Note 2) Before connecting or removing the BNC cable, make sure that no static electricity has built up on the
cable. If any, discharge static electricity.
