Enter the pH value of your
buffer solution for the proper
temperature. While the “hour-
glass” icon is blinking, the elec-
trode and temperature probe
remain in the buffer solution.

Automatic or manual temperature detection
Press cal, enter code: 1100
Select position using ,

press enter to proceed.
Remove the electrode and
temperature probe, clean them
and immerse them in the first
buffer solution (in any order).
When “Manual temp detection”
has been configured, enter the
value in the secondary display
using the arrow keys.
Press enter to start.
If an invalid code is
entered, the trans-
mitter returns to
measuring mode.
The response time
of the electrode
and temperature
probe is consider-
ably reduced when
the electrode is
first moved about
in the buffer solu-
tion and then held
still.
Transmitter in Hold

value frozen.
Sensoface inactive.
For calibration with manual buffer specification, you must enter the pH
value of the buffer solution used in the transmitter for the proper tempera-
ture. This presetting enables calibration with any desired buffer solution.
The MAN calibration mode and the type of temperature detection are
selected in the configuration mode.
