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
A. Replace the Batteries
Replace 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
battery indicator appears.
1. Shown in the right figure.
2. Take off the battery cover.
3. Remove all of the old batteries and
insert a new set of batteries ensuring
the polarities are correct.
B. Soak the Electrode, if
necessary for up to 24 hours
1. Remove the electrode cap covering the VisionPlus ORP meter.
2. Soak the ORP electrode in standard solution or distilled
water for 10 minutes before first use or after storage.
C. Setup and Calibrate the Electrode and Meter
PCE-ORP 3 must be setup and calibrated before your first use.
Please follow the instructions detailed in section USING VPCE-

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.

USING PCE-ORP 3
A. Power ON/OFF & Shutdown
Press “HOLD” key for 2 seconds or more. The unit will turn on and
enter the “Measure Mode”. Repeat the process to turn off the unit.
The unit will also automatically turn off after 10 minutes of no key
activity.
B. Set Date and Time
1. Press “MODE” key for 10seconds or more to enter“Date and Time
Set Mode”.
2. Press “HOLD” key to
selectcalendar or time
parameters.
3. Press “MODE” and “SCROLL”
keys to increase and decrease
values respectively.
4. Press “STORE” key for 2
seconds to exit and return to“Measure Mode”.

C. 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 3is equipped with a non-volatile
memory that can store up to 50 different sets of readings
6

(ABSolute & RELative mV, temperature, Time and date).Non-
volatile memory will be retained even if power is lost. When all
50 memory locations are used up, the next set of data saved
will overwrite the data stored in the first location and so on.
G. Recall Data
1. In “Measure Mode”, press “SCROLL” key 2-3 seconds, the last
set (assume it is M12) of saved data will appear.
2. By pressing the “SCROLL” key, previous ( M11) saved data will
appear.
3. Press “STORE” key for 2 seconds to exit and return to “Measure
Mode.
H. Erase Data
1. Press “SCROLL” key over 10
seconds to entererase mode.
See the figure below.
2. Press “STORE” key, the unit
will display “DATACLEAR” and
erase all data in the non-
volatile memory.
3. Press “SCROLL” key to leave
the erase mode and return to
“Measure Mode”.
ONGOING MAINTENANCE
A. Replace Electrode
It is recommended the ORP electrode be replaced every 6 to 12
months or as needed. Some applications can severely limit
the life span of an ORP electrode.
1. Unscrew the electrode collar to
remove the electrode & ATC
assembly as shown in the right
figure.
2. Remove the old electrode from the
electrode collar.
3. Insert a new electrode, make sure the electrode fit back into the
meter correctly.
4. Screw back the electrode collar.
