Temp. compensation value setting
The pH measurement value is effected by the
measurement environment Temp. value. If intend to
make the precision pH measurement, it should connect
the Temp. probe ( ATC probe, TP-07A ) to " Wire
terminals " T9, T10. Otherwise, it should adjust the
Temp. compensation values to reach the Temp. values
of the measured solution, the procedures are :
1)After select the temperature unit ( , ), press the
℃ ℉
" Set Button " ( 3-4, Fig. 1 ) twice, the " Display "
will show tPSt ", now the meter is ready for the
the Temp. compensation value setting.
2)Use the " " Button " ( 3-5, Fig. 1 ) and the "
▼ ▲
Button " ( 3-6, Fig. 1 ) to adjust the desiring
Temp. compensation value.
* If the meter already connect the Temp. probe ( ATC probe,
TP-07A ), though already adjust the Temp. compensation
value, the pH measurement value will be not effected by the
setting Temp. compensation value, it compensated by the Temp.
probe only.
* When adjust the Temp. compensation value, the " SV indicator "
( 3-3, Fig. 1 ) will light.
Hysteresis value setting
1)After select the temperature compensation value,
press the " Set Button " ( 3-4, Fig. 1 ) twice, the
" Display " will show HySt ", now the meter is ready
for the Hysteresis value setting.
2)Use the " " Button " ( 3-5, Fig. 1 ) and the "
▼ ▲
Button " ( 3-6, Fig. 1 ) to adjust the desiring
Hysteresis setting value.
* When adjust the Hysteresis value, the " SV indicator "
( 3-3, Fig. 1 ) and the " will light.
