Action Prompt
Double Press any Button MENU HOME, Hold is OFF
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 ? STABILIZING, 0.00 ppm, xxx.x mV, 0.00 ppm corrected, Accept Cal?
Press YES CAL 1 Value 0.00 ppm, Continue to CAL2? Move sensor to Air or saturated water
Press YES STABILIZING, 8.25 ppm, xxx.x mV, 8.25 ppm corrected, Accept Cal?
Press YES OFFSET: 0.00 ppm, 2.3 mV, SLOPE: 40.1 mV/ ppm (data written to Log)
Press OK Calibration complete
Press HOME Hold is ON
Press HOLD Turn off Hold
Press EXIT Main Display
