3.2 pH measurement (with ATC , automatic Temperature
Compensation)
1) All the procedures are the same as for 3.1 “pH measurement
(manual temperature setting)“, except for attachment of a
temperature probe by inserting the plug of the temperature
probe into the “Temp. Socket“ (Page 5, Fig. A-13), and immers-
ing the sensing head of the temperature probe into the measure-
ment solution.
2) The upper display will show the pH value, the bottom left
display will show the Temp. value of the measured solution, and
the bottom right display will show “Auto Temp.“ as example below:
When not in use the “Electrode Sensing Head“ (Page 8, Fig.
B-3) should always be immersed in water by part-filling
the probe cap, (Page 8, Fig. B-4) and ensuring that the cap
is firmly lifted onto the probe. Failure to do so will reduce
probe life.
3.3 mV Measurement
The instrument has a built in mV (millivolt) measurement function,
which enables you to make ion-selective, ORP (oxidation reduction
potential), and other precise mV measurements.
1) Attach the ORP Electrode by installing the “Probe Plug“ of the
ORP electrode into the “pH Socket/BNC Socket“ (Page 5, Fig. A-16).
2) Power on the meter by pressing the “Power” button once.
3) Keep pressing the “Mode” button until the display at bottom
right shows “PH“ and “Manual Temp.“ indicator.
