sensor
Temperature measurement
Set the function switch to the „C" position.
•
Connect the probe's connector to the „K
•
TEMP" connector (note the polarity) and the
other end onto the measured surface. The
temperature is displayed on the screen in °C
units.
The device operates with a special temperature
measurement probe. If the probe is not connected to
the connector, the device shows the temperature of its
environment.
Do not connect external voltage to the connectors if the
device is in temperature measurement mode.
