Performing fine adjustment
1. Switch off fine adjustment.
2. Run up first working point (lower measuring point, value as low and constant and possible). Read the measured value
on the device, read the reference value on the reference measuring device. Note both values.
3. Run up second working point (upper measuring point, value as high and constant and possible). Read the measured
value on the device, read the reference value on the reference measuring de vice. Note both values.
4. Switch on fine adjustment, enter device's measured values from the first and second working point (actual start value
(15.0) and actual end value (70.0)); then enter the reference measuring device's reference values from the first and
second working point (target start value (20.0) and target start value (80.0)).
The following diagram shows the changes in the characteristic line caused by the measured value offset (point of in-
tersection with the x axis as well as the gradient) based on the values from the example above (x = reference value,
Y = display value).
1. Characteristic line before fine adjustment
2. Characteristic line after fine adjustment
Reverse fine adjustment
The following settings must be made to reverse the fine adjustment: actual start value = target start val ue; actual end
value = target end value
Switching off fine adjustment leads to this being reversed.
