1. CALIBRATION
All MicroTron controllers are factory calibrated for
temperature, conductivity, pH and/or ORP (if present).
These values should be verified for accuracy, and
adjusted as per the instructions listed below and to the
side.
Calibrating the temperature
reading, press SET UP/
RUN button. The “CALIBRATION” screen will appear.
Press ENTER and the screen will read “CALIBRATE
F”. Press ENTER to log in the new reading. To display
the reading in degrees Celsius, press the decimal key.
High Temp Alarm Set
- If this is exceeded the Alarm
will activate, set to 0 to disable.
Calibrating the Conductivity
with the probe in a
known solution, select “CALIBRATE uS” from the
“CALIBRATION” menu. Press CLEAR, then key in the
corrected conductivity value. Press ENTER to log in
that reading.
Calibrating the pH
with the probe in solution on line.
Select “CALIBRATE PH” from the “CALIBRATION”
menu. Press CLEAR, then key in the corrected pH
value. Press ENTER to log in that reading.
Calibrating the ORP
with the probe in solution on line.
Select “CALIBRATE ORP” from the “CALIBRATION”
menu. Press CLEAR, then key in the corrected ORP
value. Press ENTER to log in that reading.
The limits on this factor are from 50% to 200% and any
entry which would lead to a factor outside this range
will cause it to default back to the previous value.
NOTES:
1. After entering a new numerical value hit the
ENTER key to accept value and advance.
2. For severe calibration problems, see Reset
Zero and Recentering pH on page 22 & 23.
