AutoOff:

AutoOff is used to define an interval in minutes after

which the instrument switches off automatically. The setting OFF

(<1) deactivates the automatic switch off. Select with     and      ;

confirm with      .

One point temperature calibration

CAL1:

CAL1 (one point calibration) gives the user the possibility to

define an offset for temperature 1. The offset is displayed in the

lower part of the screen. Maximum offsets are:

PT100 channel: +/- 2.5°C/°F in 0.01°C/°F steps 

TC channel: +/- 10°C/°F in 0.1°C/°F steps.

The offset will be valid over the complete measuring range. 

Factory calibration can be obtained by setting the offset to 0.0.
