Press HOLD
Hold freezes 4-20 mA Output and locks Alarm Relays during Calibration
Press CAL
Is this a new Sensor? (Yes erases CAL Log in INFO, NO adds CAL to existing Log)
Press Yes/NO
Place Sensor in CAL 1 Solution ( use 0.00 ppm solution) or CAL 2 Solution (Air)
To perform zero CAL press CAL 1, to skip zero cal press CAL 2
Press AUTO then CAL ?
