4. MEASURING PROCEDURE
Terminal layout Fig. 2
4-1 Terminal connection
1)Input the ACV power ( 90 to 260 ACV ) to T1, T2.
Do not input the
over voltage to the
AC input terminals.
2)Connect the " pH Control Relay " output from T3, T4.
Connect the " Temp. Control Relay " output from T5, T6.
4-2 pH calibration
When the first time use the pH electrode or the pH
electrode already be used a long period, then before
the measurement, it should make the
calibration first, the calibration procedures, refer to
page
Chapter 5. pH CALIBRATION PROCEDURES

4-3 pH measurement ( with ATC probe )
1)Prepare the optional Temp. probe ( ATC probe TP-07A )
connect the Temp. Wires ( 3-19, Fig. 1 ) to the " Wire
terminals " ( 3-12 ) T10, T9 ( bare wire ).
Prepare the optional pH electrode ( For example PE-21,
PE-03... ), Connect the " pH Electrode plug " ( 3-16,
Fig. 1 ) to " BNC Input socket " ( 3-14, Fig. 1 ).
2)Power on the meter, immerse the above pH electrode
and the Temp. probe into the measuring solution.
The " Display " ( 3-1, Fig. 1 ) will show the pH value,
in the same time the " pH indicator " ( 3-10, Fig. 1 )
will light.
3)Press the " PH/Temp Button " ( 3-7, Fig. 1 ) once,
the " Temp. indicator " ( 3-11, Fig. 1 ) will light, the
" Display " ( 3-1, Fig. 1 ) will show the Temp. value
that sensing from the Temp. probe ( ATC probe
TP-07A ).
* Press the " " PH/Temp Button " ( 3-7, Fig. 1 ) once again,
the " Display " will return the " pH value ", in the
same time the " pH indicator " ( 3-10, Fig. 1 ) will light again.
* The pH measurement value will be compensated automatically
by the Temp. value that sensing from the Temp. probe
( ATC probe, TP-07A ).
* During the Temp. measurement, if intend to change the default
Temp. unit from the to , refer to page 10.℃℉
4-4 pH measurement ( without ATC probe )
1)Prepare the optional pH electrode ( For example PE-21,
PE-03... ), Connect the " pH Electrode plug " ( 3-16,
Fig. 1 ) to " BNC Input socket " ( 3-14, Fig. 1 ).
Not connect the Temp. probe ( ATC probe , TP-07A ) to
the " Wire terminals " ( 3-12 ) T10, T9.
