sive cleaner, but a dry or damp cloth.
• Please store the measuring instrument in a dry and
clean place when not in use.
• Avoid any force like shocks or pressure to the instru-
ment.
• Do not use force to connect the probe or interface
plugs in. The interface plug is different from the
probe plug.
• If no sensor is connected to the instrument while
switching on "OPN" shows on the display.
• A retractable stand on the back of the instrument
allows it to be used as a bench top instrument.
1.2. Operation
Before switching on the instrument, connect the

value. By using the Hold button you will switch to the
next figure or you will end the adjustment.
Note: The mentioned offset will add or subtract
(negative value) from the measurement.
Note: When the offset is not equal to 00.0 the Celsius-
sign "°C" will be not completely displayed.
Offset has been not Offset has been
changed e.g.: 00.0 changed e.g.: -00.5
1.5 Recalling the memory data (HOLD MAX MIN AVE)
After pushing first time the key [HOLD MAX MIN AVE]
the actual value will be held on the display. Pushing
again the key [HOLD MAX MIN AVE], the saved maxi-
mum-, minimum and average value will be displayed.
Note: During the recall of the memory data the extre-
mes (MAX MIN) and the average value (AVE) will not
be calculated or carried on.
Clearing the memory (MAX MIN AVE)
Press [CLEAR] key once to erase the stored maximum,
minimum and average from memory

a full segment test (Fig. 1) for 1,5 sec. afterwards the
instrument starts operating in measurement mode
indicating the actual measurement temperature.
1.4 Functions
1.4.1 Measuring unit switching °C and °F (Celsius / Fahren-
heit)
To change the measuring unit push ON/OFF- and
MEM/OUT-Button simultaneously until the measure-
ment value will shown.
1.4.2 CAL-option (how to adjust the instrument)
The instrument offers an easy calibration function to
adjust the temperature at one point – to compensate
sensor tolerances.
Push once the Hold-Button. On the bottom of the dis-
play you will see HLD and the displayed measurement
value is "frozen”. By using now the MEM IN-Button
the instrument switch to CAL-mode. On the instru-
