not AUTOLOCK. In this case, use the pH NON- AUTOLOCK
mode for measurements.]
b.
Measurement with manual temperature compensation in
the pH-AUTOLOCK mode.
1.
Connect the pH electrode to the BNC connector of the unit.
The “MAN” icon will lit up. Set unit to display the sample
temperature by pressing the “UP” and “DOWN” keys (-10.0 to
120.0
℃
).
2.
Press “MODE” key until “pH” icon and “AUTO” icon lit up.
3.
Rinse the pH electrode probe with distilled water and immerse
it in the sample to be measured. Remove any air bubbles
trapped around the probe by shaking or stirring the probe.
4.
Press the “MEA./EFF.” key. The “WAIT” icon will start flashing.
The unit is waiting for a stable reading. The meter will track the
pH value as sensed by the pH electrode probe.
5.
When the “WAIT” icon disappears and the “HOLD” icon is
displayed, the reading is then locked and will not respond to
further changes from sample. The pH value shown is the pH
value of the sample at the set sample temperature.
[
Note:
For samples that are inherently unstable, the unit will
not AUTOLOCK. In this case, use the pH NON- AUTOLOCK
mode for measurements.]
c.
Measurement with an ATC/Temp probe in the pH NON-
AUTOLOCK mode.
1.
Connect the pH electrode to the BNC connector and the
ATC/Temp probe to the ATC/Temp connector of the unit. The
“ATC” icon will lit up.
2.
Press “MODE” key until the “pH” icon lit up.
3.
Rinse the pH electrode and ATC/temp probe with distilled
water and immerse them in the sample to be measured.
4.
Allow sufficient time for the display to stabilize. The instrument
will display the pH value of the sample at the displayed sample
temperature.
d.
Measurement with manual temperature compensation in
the pH NON-AUTOLOCK mode.
1.
Connect the pH electrode to the BNC connector of the unit.
