solution's temperature exactly, the procedures
refer chapter 9-7, page 38.
4)Hold the " Electrode Handle " ( 4-2, Fig. 2 ) by hand
and let the " Sensing head " ( 4-3, Fig. 2 ) immersed
wholly into the measured solution and little shake the
probe.
5)The up main display will show the pH value, the left
bottom display will show the setting manual Temp.
value.
5-2 pH measurement ( ATC , automatic Temperature )
1)All the procedures are same as
5-1 pH measurement ( manual ATC )
but should prepare one temperature probe ( optional,
TP-07 ), insert the TP-07's plug into the " Temp. Socket "
( 3-14, Fig. 1 ), immerse the sensing head of temperature
probe ( TP-07 ) into the measurement solution.

bottom display will show the sensing Temp. value of
the measured solution.
When not use the Electrode, it should immerse
the " Electrode sensing head " ( 4-3, Fig. 2 ) into
the " Protection bottle " ( 4-4, Fig. 2 )
13

5-3 mV Measurement
The instrument build in mV ( millivolt ) measurement
function, which enable you to make ion-selective, ORP
(oxidation-reduction potential), and other precise mV
measurements.
1)Prepare the ORP Electrode ( optional, ORP-14 ), install
the " Probe Plug " of ORP electrode into the " pH
Socket/BNC Socket " ( 3-11, Fig. 1 ).
2)Power on the meter by pressing " Power Button "
( 3-2, Fig. 1 ) once.
Select the measurement mode to " pH, mV ( ORP )
measurement ". refer chapter 4, page 11 .
Pressing the " Function Button " ( 3-6, Fig. 1 )
once until the Display show " mV " indicator.
3)The up main display will show the mV value.
5-4 pH calibration
Calibration Consideration
The most ideal pH ELECTRODE generates 0 mV at pH
7.00 ( 177.4 mV at pH 4 ) and meter has been always
calibrated with signals which simulate the most ideal pH
ELECTRODE ( based on 25 ambient environment ).℃
However not every pH ELECTRODE is as accurate as the
most ideal one, so calibration procedures are necessary
to be done before the first time measurement.
In addition to the first time measurement, users are also
recommended to execute the calibration procedures to
ensure the high accuracy measurement.
14

Required Equipment for Calibration
1)pH ELECTRODE ( optional ).
2)pH buffer solutions ( optional ).
Calibration Procedure
1)Prepare the pH Electrode ( optional ), install the
" Probe Plug " ( 4-1, Fig. 2 ) into the " pH Socket/BNC
Socket " ( 3-11, Fig. 1 ).
2)Power on the meter, set the mode to the pH
measurement, the right bottom display will show " pH ".
3)Adjust the " Temperature Compensation Value " to
make it same as the temperature value of the pH
buffer solution.
* Manual temperature compensation value
adjustment procedure, refer to 9-7, page 38.
* Automatic temperature compensation, refer
to 5-2, page 13.
.
4)Hold the " Electrode Handle " ( 4-2, Fig. 2 ) by hand
and let the " Sensing head " ( 4-3, Fig. 2 ) immersed
wholly into the measured solution and little shake the
probe.
Display will show the pH value.
* If use the ATC probe, should immerse the
ATC probe into the solution together.
15

5)Use the two fingers to press the " REC Button " ( 3-4,
Fig 1 ) and " HOLD Button " ( 3-3, Fig. 1 ) at the
same time. Until Display will show the following screen
then release the both fingers.
PH
CAL
6)Press the " Button " ( 3-9, Fig. 1 ) or " Button "▲▼
( 3-10, Fig. 1 ) once in sequence to select the following
screen.
a For pH 7.00 calibration

When select the
CLr
CAL
and press the " Enter Button " will clear the existing
calibration data.
7)Fine adjustment of calibration value
During the calibration when the main Display ( 7.00,
4.00 or 10.00 ) is flashed, it can use the " Button "▲
( 3-9, Fig. 1 ) or " Button " ( 3-10, Fig. 1 ) to make▼
the fine adjust of the calibration value, for example
the exact calibration value is 4.01, 4.02, 3.98....
7.01, 7.02. 6.98....10.01, 10.02, 9.98
After the fine calibration value is adjusted, release the
Button ( Button ), the main Display will be flashed▲▼
few second then execute the calibration according
the new calibration value.
7)The complete procedures should execute
the two calibration points :
pH7 calibration, pH4 calibration
pH7 calibration, pH10 calibration
* The calibration procedures should execute start from
pH7 calibration then follow pH4 ( or pH10 ) calibration.
* Rinse the electrode with distilled water again when
make each point calibration ( pH7, pH4 or pH10 ).
* Repeat above two points procedures two times at least.
17

5-5 ORP calibration
1)Prepare the ORP electrode ( optional, ORP-14 ), connect
the ORP electrode to the meter.
2)Power on the meter, set the mode and the function
to " mV ", refer chapter 5-3, page 14.
3)Immerse the sensing head of ORP electrode into the
ORP standard buffer solution, the up display will
show the ORP value in mV.
4)Use the two fingers to press the " REC Button " ( 3-4,
Fig 1 ) and " HOLD Button " ( 3-3, Fig. 1 ) at the
same time. The display will show the following screen
as example, then release the both fingers.

5)Use " Button " ( 3-9, Fig. 1 ), " Button " ( 3-10,▲▼
Fig. 1 ) to adjust the up display value exact same as
the standard ORP buffer solution value. Press the
" Enter Button " will save the calibration the data
and finish the calibration procedures.
* The ORP calibration procedures are available
only the ORP buffer solution value is > 100 mV.
* If the ORP calibration procedures is less than
