INITIAL INSPECTION AND ASSEMBLY
Carefully unpack the instrument and accessories. Inspect for
damages made in shipment. If any damage is found, notify your
Jenco representative immediately. All packing materials should be
saved until satisfactory operation is confirmed.
BEFORE YOUR FIRST USE

Replace the Batteries
Rep
lace the battery when the blinking
low battery indicator “BAT ” appears on
the lower left hand side of the LCD
screen. The instrument can operate
within specifications for
approximately2~3 hours after low

OPERATION MODES AND KEYPAD OPERATIONS
A. Operation Modes
. PCE-ORP 3 meter has 7 operation modes:
1. Measure Mode.--Measure Mode is used to make all absolute or
relative ORP and temperature measurements.
2. Calibration Mode.--Calibration Mode is used to perform offset
voltage adjust.
3. Hold Mode.--Hold Mode is used to display held measured values
for increased ease of use.
4. Recall Data Mode.--Recall Data mode is used to display
measured data which have been stored in memory.
5. Store mode.--Can save up to 50 set data in non- volatile memory.
6. Date and Time Set Mode.--Date and Time Set Mode is used to
change date and time.
7. Erase Mode.--Can erase 50 set data in non- volatile memory.

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
