Meter Verification Procedure (pH and pH/ISE Channels Only)
1.
After completing the self test, the meter will return to the measurement mode. Keep all of
the electrodes and sensors disconnected from the meter and keep the BNC shorting cap
attached to the BNC input on the meter.
2.
Set the measurement mode to pH. The meter should read a steady 7.000 pH
±
0.002 pH.
a.
If the meter does not read a steady 7.000
±
0.002, perform a one point pH calibration
with the BNC shorting cap attached to the BNC input. Set the pH value to 7.000 and the
slope value to 100.0. Refer to the pH Calibration section for detailed instructions.
3.
Set the measurement mode to mV. The meter should read a steady 0.0 mV
±
0.2 mV.
a.
If the meter does not read a steady 0.0 mV
±
0.2 mV with the BNC shorting cap
attached to the BNC input, contact Technical Support.
