Display Action Remark
Buffer recognition
While the “hourglass” icon is
blinking, the electrode and
temperature probe remain in
the first buffer solution.
Automatic calibration with Calimatic (BUF -xx-)
Automatic or manual temperature detection
Press cal, enter code: 1100
Select position using ,
edit number 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.
Buffer recognition terminated,
the nominal buffer value is
displayed.
Transmitter in Hold
mode, measured
value frozen.
Sensoface inactive.
The transmitter can only operate properly when the buffer solutions used
correspond to the configured set. Other buffer solutions, even those with
the same nominal values, may demonstrate a different temperature
response. This leads to measurement errors.
