1.1 General advice
• For cleaning the instrument please do not use
abrasive cleaner but a dry or wet piece of cloth.
• Please store the measuring instrument in a dry and
clean place.
• Avoid any force like shocks or pressure to the
instrument.
• 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 „open“ shows on the display (Please
refer to chapter error codes/troubleshooting).
• 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
probe/s to the instrument and insert the battery
(Please refer to chapter 6. Power supply / battery
changing). A number on the instrument's housing
marks each port.
1.3 Switching on and off
By operating the ON/OFF-key the instrument swit-
ched on or off. After switching on the instrument
indicates a full segment test for 1,5 sec., afterwards
the instrument shows the calibration-code and the
adjusted measurement category for channel 1. (Only
2-channel instruments: After additionally 1,5 sec.
the instrument shows the calibration-code and the
adjusted measurement category for channel 2.)
Then it starts operating in measurement mode in-
dicating the actual measurement value (for example:
temperature). All instruments display the measure-
ment value of channel 1 on the top display line (big
display line). Directly below you will see the trending
bargraph. The second channel of our 2-channel
instruments you will see on the bottom line (small
display line).

Example of channel information after switching on.:
channel 1
Line 1: [oFF P = calibration code of channel 1
according to standard linearization (DIN), probe selec-
tion of channel 1 = Pt100.
channel 2
Line 2: [oFF P = calibration code of channel 2
according to standard linearization (DIN), probe selec-
tion of channel 2 = Pt100.
