Before switching on connect the probe(s) to the intended female connector of the
measuring instrument and make sure that a fully charged 9 V battery is inserted
(2 batteries are included in the scope of delivery). The probe connection sockets
are marked on the instrument case with 1 or 2 correspondingly. The USB interface is
marked next to them.

To switch the measuring instrument on and off, press the ON/OFF button. After
switching the instrument on all segments are indicated on the display for 1.5 seconds
(full segment indication). For the next approx. 1.5 seconds the instrument indicates the
set probe calibration code as well as the set measurement parameter for channel 1 (e.g.
CoFF for DIN characteristic curve and P for Pt100). After that the calibration data for the
2nd channel are displayed.
Finally, the instrument switches automatically to the measuring mode and displays the
current measurement parameter. In the upper display line (large display) the measured
value is displayed, a bargraph is located beneath it for graphical measured value
representation. In all 2-channel instruments the 2nd channel is displayed in the lower
display line (small display).
