Items that can be adjusted by the user include SSR (ON or OFF), Events E-1, E-2 and
E-3(ON or OFF) and PWR. The SSR and PWR items can be used to test the solid
state relay for proper operation. The SSR item allows the SSR to output 100% (ON) or
0% (OFF). The PWR item allows for adjustable output from 0% to 100%. to
implement, adjust the PWR level with the +/- keys and turn on the heater relay.
RCVR SEN and RCVR HIL are used to restore the factory calibration should a
calibration error occur.
