Operation
Note
If the meter is connected to a PC and is used to take
measurements in a grounded liquid, measuring errors
may result.
Note
Prior to first use, the cell constant, temperature com-
pensation and time and date must be checked and set,
if required. The cell constant is printed on the sensor
head and listed in the sensor specifications (see also
Note
The calibration and configuration data remain perma-
nently stored both with the meter switched off and
with the batteries removed (battery replacement).
Start-up
Pressing on/off switches the meter into measuring
mode. After power-on, the meter determines the con-
nected temperature detector and performs a self test:
• Simultaneous appearance of all display segments
• Display of the model number
• Display of the software version
Note
For recognition of the temperature detector, the con-
ductivity sensor must be connected to the meter before
power-on. The temperature detector is only recognized
during the power-on procedure after pressing on/off.
Note
The meter can also be switched on with meas.
However, in this case only a short test is performed and
the temperature detector is not identified. The meter
assumes that the last temperature detector identified
is used.
Note
The SE 202 and SE 204 sensors have an integrated NTC
temperature detector.
