The automatic two-point calibration recognizes the following buffer sets:
4.7.4 Calibrating the conductivity measuring cell
Please note the special instructions on calibration in the operating
manual of your sensor in addition to the calibration procedure on the
instrument.
Menu item Explanation
input Input field for calibration values ( asymmetrie
,
slope )
temp. offs. Input field for offsetting the temperature value
(positive or negative)
two point Starts the procedure for the two-point calibration with
manual input of the calibration solution(s)
Any calibration solutions are allowed.
automatic Starts the procedure for the automatic two-point
calibration. The measuring transmitter automatically
recognizes the calibration solution used. The target
values do not have to be entered manually.
The automatic recognition works for DIN/NIST and
Technical buffers (TEC).
