SET BALANCE
adjusts the balance of a bridge-type sensor and must only be performed with ZERO gas on
the sensor. Balance is similar to a very coarse ZERO calibration and does not need to be precise since
subsequent calibrations will correct for small errors. ZERO gas applied to the sensor should provide a
Reading of
– 3 to +3 on the SENSOR BALANCE menu.
SET VOLTAGE
adjusts the excitation voltage applied to bridge type sensors and may vary from 2 to 6
volts. Local Smart Sensors automatically adjust the excitation voltage to match the needs of the sensor.
Remote sensors require manual adjustment. Excitation voltage must be measured
at the sensor ;
therefore, if the sensor is mounted some distance away from the GASMAX II, the excitation voltage may
have to be higher to compensate for losses in field wiring.
WARNING: C I G ’ T EXCITATION VOLTAGE MAY DAMAGE OR DESTROY THE
SENSOR.
