1 Temperature of analyzer section with
average ambient temperature (in ˚C;
see function 60, identifier 2)
2 Change in display with increase in
temperature (function 61, identifier 4)
3 Change in display with reduction in
temperature (function 61, identifier 4)
Procedure
1. Calibrate zero of basic temperature
(function 5)
2. Switch on measuring range 1
3. Select function 71 and enter a value of
zero for identifiers 2 and 3
4. Measure (see example)
5. Enter identifier and setpoints under
function 71
Caution! Function 71 might influence zero!
