SECTION 5 - ANALYZER CALIBRATION
Model C53 Conductivity Analyzer (universal-mount 1/2 DIN)

5.5 Analog Outputs
(1 and 2) Calibration
☞
The analyzer analog outputs are factory-calibrated. How-
ever, they can be re-calibrated at any time if desired.
These
instructions calibrate Output 1. Calibrate Output 2 in the
same way using its respective menu screens.
NOTE:
When the passcode feature is enabled (Section
4.7), you must successfully enter the passcode
before attempting to calibrate the analog outputs.
When an output is configured to be 0-20 mA, the
analyzer will calibrate the 4 mA and 20 mA values
(not the 0 mA value). Also, the analyzer adjustment
range for output values during calibration is ± 2 mA.
