Calibration
By calibration the pH meter is adjusted to zero point and
slope of the electrode used.
For calibrations and measurements at temperatures other
Note
than room temperature, the following must always be ob-
served:
Not only the buffer solution and the measured medium, but
also the electrode must be brought to the corresponding
temperature before the calibration is started or the mea-
sured value is read.
Calimatic
For calibration using Calimatic
automatic
tion, you only have to enter the buffer set used once in the
configuration menu. With the patented Calimatic
calibration
the meter automatically recognizes the buffer solutions,
calculates the electrode zero point and slope and carries
out the corresponding adjustment.
The meter can only operate properly when the buffer solu-
Note
tions used correspond with the buffer set selected during
buffer selection.
Other buffer solutions, even with the same nominal values,
may demonstrate different temperature behavior, which
leads to measurement errors.
Pressing cal activates calibration.
cal
Calibration can be exited again by pressing meas. If ex-
ited prior to entry of the first calibration point, zero and
slope of the last calibration are displayed for a moment.
Immerse electrode and temperature probe in the first buffer
solution. Either buffer solution can be used first.
Press cal again to start calibration. If you do not want to
calibrate, press meas to cancel the process.
