1.2 Operation and maintenance advice
■ Operation with battery or accu
If ∆ and ´bAt´ are shown in the secondary display the battery
has been used up and needs to be replaced, or resp. the accu
is empty and has to be recharged. The device will, however,
operate correctly for a certain amount of time. If ´bAt´ is shown
in the upper display the voltage is too low to operate the device;
the battery or accu has been completely used up.
We recommend to take out battery/accu if device is not used for a
longer period of time!
■ Mains operation with power supply
When using a power supply please note that operating voltage
has to be 10.5 to 12 V DC. Do not apply overvoltage! Cheap
12 V-power supplies often have excessive no-load voltage.
We, therefore, recommend using regulated voltage power
supplies. Trouble-free operation is guaranteed by our power
supply unit.
Prior to connecting the power supply to the mains make sure
that the operating voltage stated at the power supply is
identical to the mains voltage.
■ Connecting/Changing Sensors
Switch off device before changing the sensor. Connect sensor
before switching on the device. In such case take the plug not
at the casing but at the buckling protection at the end of the
plug. When connecting the probe the plug will slide in smoothly
if plug is entered correctly. To disconnect sensor plug do not
pull at the cable but at the plug.
Probes may be extremely hot or cold. Precautions must be
taken to prevent personal injury or damage to objects.
