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.
