7200 Monitor Instruction Manual
20.4 Calibration
Not Available - Sensor Fault
If one of the above sensor faults is present, it is not possible to perform a calibration. Clear the sensor fault and try
again.
Sensor Input Too High (Set Zero)
The data collected for the zero operation was above the allowed maximum for a zero operation. This can be caused
by a dirty zero solution, fouling on the sensor or a fault with the sensor.
Sensor Input Too Low (Set Zero)
The data collected for the zero operation was below the allowed minimum for a zero operation. This generally
indicates that the sensor is faulty.
Sensor Input Too Low (Set Span)
The data collected for the calibration operation was below the allowed minimum for the span to be set. This occurs
when sensor signal in the calibration solution is too close to the sensor signal in the zero solution. This can be caused
by a too clear calibration solution, the wrong sensor type or a fault with the sensor.
20.5 Air Clean Systems
Service Air Pump *
The air clean pump requires servicing (pump run hours are greater than service life). Service the air pump then use
reset clean count to zero pump run time and clear service sensor fault.
