Calibration
l Switch the meter to the mV measuring mode.
l Using the enclosed screw driver, set the zero point of the SenTix FET
sensor so that the indication of the pH meter is within a tolerance of 0 +
10 mV. Otherwise, calibration can be affected.
Note
The sensor has an automatic switch-off function. It automatically switches off
the sensor approx. one hour after switching on.
Calibrate the SenTix
the pH meter.
Note
For precise measurements, attach the light shield to the measuring tip when
calibrating. We recommend to use the light shield for every calibration and for
measurements in liquid media.
Note
The sensor evaluation that appears on WTW meters does not have any
significance with the SenTix
®
FET-D/B sensor according to the operating manual of
