Calibration by direct entry of the cell constant (
AutCAL OFF
)
Operation
SE 202 and
SE 204 sensors
For the conductivity sensor models SE 202 and SE 204, the
cell constant is specified with a tolerance of 2 % and 1.5 %.
This cell constant is entered and stored in the calibration
mode (
AutCAL OFF
). An additional calibration with calibra-
tion solutions is not necessary.
SE 202 sensor: c = 0.1 cm
–1
SE 204 sensor: c = 0.475 cm
–1
Press cal to activate calibration. The cell constant deter-
mined or set during the last calibration is displayed.
Pressing meas exits calibration again.
Use

to set the cell constant of the sensor and
confirm by pressing cal. The meter will then switch back to
the measuring mode.
