Digital pH Meter
• Sets the calibration values during Relative mV
or Temperature calibration. Scroll through each
SETUP and its sub group menu. Scroll through
Print Function menu and its parameters.
SETUP
- Activates the parameter setting menu
to allow you to customise meter configuration,
view calibration points and electrode offset
data, select auto power off, reset meter and
clear memory.
MODE
- Select the measurement parameter
option between pH, Relative mV or mV.
- Allows transfer of current measurement
or stored data to either the printer or the computer.
5.3 Meter Preparation
Inserting the Batteries
This meter is packaged with 4 “AAA” alkaline batteries
required for its operation. To insert the batteries into
the meter, follow the procedure outlined below.
1
Open the battery compartment by pressing
down the catch of the battery cover.
2
Insert the batteries correctly according to the
marked polarity of the battery compartment.
3
Close the battery cover, ensuring the catch
is locked in position. Your hand held meter
is now ready for operation.
Connecting the Electrode
and Temperature Probe
The meter uses any standard pH, ORP, or ISE electrode
with BNC connector. For Automatic Temperature
Compensation (ATC), the meter requires a temperature
probe with a phono jack connector. Use either:
• Electrode with BNC connector and separate
temperature probe with phono jack connector
(PH5-TEM01 PI 35613-05).
• A “3-in-1” combination pH electrode with
temperature probe.
Connecting pH, ORP or ISE Electrode
1
Slide the probe’s BNC connector over
the meter’s BNC connector socket.
2
Rotate and push the connector
clockwise until it locks.
3
To remove electrode, push and rotate the connector
counter clockwise and pull it away from the meter.
Connecting Temperature Probe
1
Insert the phono jack connector of the
electrode to the connector on the meter.
2
To remove pull away gently for a complete removal.
CAUTION:
Do not pull on the electrode cord to
avoid internal wire breakages.
Attaching the Electrode Holder to the Meter
Two electrode holders are provided.
1
Locate the slot on the right-hand side of the meter.
2
Slide the flange of the holder into the slot.
To attach a second electrode holder:
One holder can be attached onto another.
1
Align the flange of the second holder
with the slot of the first holder
2
Slide the flange of the second holder
into the slot of the first holder.
NOTE:
Holders are designed for probes
12mm in diameter.
NOTE:
Forcing the electrode into the opening
may damage the holder or your electrode.
Connecting the AC/DC Adapter
The meter can also operate on mains power
using an AC/DC power adapter (sold separately).
IMPORTANT:
Switch off the meter and the
power source of adaptor before plugging in.
1
Switch off the meter and power sources.
2
Select the correct AC/DC Adaptor either at
120/220V AC (output Voltage:9 to 15V DC,
Current:>=50mA).
3
Insert the power adapter D.C. jack into the
meter power socket.
4
Switch on the power source of the adaptor
followed by the meter.
5.4 Calibration
Important Information on Meter Calibration
When re-calibrating, existing pH/R.mV and
mV calibration points are replaced on a point
by point basis.
