Calibration
Calibration procedure
Caution
Three short beeps indicates a checksum failure of internal non-volatile
memory. A checksum failure prevents the instrument from recovering
calibration data. If this failure occurs, do not continue to use the instrument
and contact an AMI Technical Support Representative for further assistance.
3. Fill the target vessel so that all plate pairs installed on the sensor are fully
immersed in the liquid.
4. While the plate pairs are submerged in the liquid, press the MAX calibration
button. The instrument will again sound a constant tone for 2 seconds. One
short beep will sound at the end of the MAX calibration indicating successful
calibration and storage to internal memory.
Note
The calibration procedure may be reversed, i.e. the MAX calibration can be
performed before the MIN calibration if necessary. The MIN and MAX
calibration values can be performed repeatedly in any order, but a valid MIN
and MAX calibration pair is required for operation.
5. Proceed to the Operation section for directions for utilizing the instrument.
