Relative ORP Calibration
If the user requires a relative ORP calibration, follow these steps:
1. Clean and dip meter into
standard solution .
2. Wait reading stable, press
“MODE” key for 2 to 3 seconds
to enter “Calibration” mode and
enter new relative ORP value.
3. Press “HOLD” key to move the
digit position ( polarity & digit).
4. Press “MODE” and “SCROLL”
keys to increase and decrease
values respectively.
5. Press “STORE” key for 2 seconds to exit and return to measure
mode displaying absolute ORP value.
6. Press “MODE” key to display relative ORP value.
Note:
1. The ORP offset calibration is only needed in some applications.
2.
Don’t enter calibration mode when absolute reading is over ±1000
mV range.
D.
Measure
The ORP/TEMP can be used to measure absolute or relative ORP
values.
1. Dip the meter into the test solution in the “Measure Mode”.
2. Press “MODE” key to select absolute or relative ORP readings.
E.
Hold Data
1. When the ORP reading is
stable, press “HOLD” key once
to lock the reading.
Note:
The unit cannot be power
off in “Hold Mode”.
2. Press “HOLD” key again to
unlock reading and the unit will
return to “Measure Mode”. The
unit is now ready for another
measurement.
F.
Save Data
1. Either in the “Hold Mode” or the “Measure Mode”, press “STORE”
key for 2-3 seconds. The “ SAVE” and “M-XX” icons will appear
indicating the reading has been saved and stored in memory
location XX. The unit will automatically returns to “Measure Mode”
and ready to perform other task.
Note:
The
PCE-
ORP 3
is equipped with a non-volatile
memory that can store up to 50 different sets of readings
