4. MEASURING PROCEDURE

Terminal layout
4-1 Terminal connection
1)Input the ACV power ( 90 to 260 ACV ) to T1, T2.
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
