5. PH/mV MEASURING and
CALIBRATION PROCEDURE
The meter default function are following :
* The display unit is set to pH.
* The temperature unit is set to ℃.
* Manual ATC ( without connect the ATC probe )
* Auto power off.
If the meter is first time to connect
the pH electrode, it should make the
calibration before operation, the
calibration procedures refer to
chapter 5-4, page 15.

5-1 pH measurement ( manual Temp. compensation )
1) Power on the meter by pressing " Power Button "
( 3-2, Fig. 1 ) once.
Use the " Function Button " ( 3-6, Fig. 1 ) Key, select to
pH measurement Function.
refer to Chapter 4, page 12.
2) Prepare the pH Electrode ( optional ), install the
" Probe Plug " ( 5-1, Fig. 2 ) into the " PH Socket/BNC
Socket " ( 3-16, Fig. 1 ).
3) Adjust the manual Temp. value same as the
solution's temperature exactly, the procedures
refer chapter 10-8, page 37.
4) Hold the " Electrode Handle " ( 5-2, Fig. 2 ) by hand
and let the " Sensing head " ( 5-3, Fig. 2 ) immersed
wholly into the measured solution and little shake the
electrode.
5) The main display will show the pH value, the
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 Temp. compensation)
but should prepare one temperature probe ( optional,
TP-07 ), insert the TP-07's plug into the " Temp. Socket "
( 3-13, Fig. 1 ), immerse the sensing head of temperature
probe ( TP-07 ) into the measurement solution.
2) The main display will show the pH value, the bottom
display will show the sensing Temp. value of the
measured solution ( measured from ATC probe, TP-07 ).
14

When not use the Electrode, it should immerse
the " Electrode sensing head " ( 5-3, Fig. 2 ) into
the " Protection bottle " ( 5-4, Fig. 2 )
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) Use the " Function Button " ( 3-6, Fig. 1 ) Key, select to
mV ( ORP ) measurement Function.
the Display unit will show " mV "
2) Prepare the ORP Electrode ( optional, ORP-14 ), install
the " Probe Plug " of ORP electrode into the " PH
Socket/BNC Socket " ( 3-16, Fig. 1 ).
3) The 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.
15

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 " ( 5-1, Fig. 2 ) into the " PH Socket/BNC
Socket " ( 3-16, Fig. 1 ).
2) Power on the meter by pressing " Power Button "
( 3-2, Fig. 1 ) once.
Select the Meter's measurement Function to " 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 10-8, page 36.
* Automatic temperature compensation, it
should plug in the ATC probe ( optional, TP-07 ).
.
4) Hold the " Electrode Handle " ( 5-2, Fig. 2 ) by hand
and let the " Sensing head " ( 5-3, 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 imerse the
ATC ptobe into the solution together.

5)
Use the two fingers to press the " ▲Button " ( 3-5,
Fig 1 ) and " ▼Button " ( 3-6, Fig. 1 ) at the
same time. Until Display will show the following screen
then release the both fingers.

6)
Press the " ▲Button " ( 3-5, Fig. 1 ) or " ▼Button "
( 3-6, Fig. 1 ) once in sequence to select the following
screen.
a For pH 4.00 calibration

* After the above a, b, c screen is selected, then cooperate
the relative standard solution, for example the
b screen should cooperate the pH 7.00 standard solution.
a screen should cooperate the pH 4.00 standard solution.
Press the " Enter Button " ( 3-8, Fig. 1 ) will
save the calibration data and finish the calibration
procedures.
* If select the d screen, press the " Enter Button " (
3-8, Fig. 1 ) will clear existing calibration data.
7) The complete procedures should execute
the two calibration points :
PH7 calibration
PH4 calibration ( or 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.
