6 Configuration

Performing fine adjustment

1) Determine the lower value (as low and constant as possible) with the reference measuring

device.

Example: Set furnace temperature to 20 °C.

2) Enter the display value as the actual start value and the reference value as the target start

value.

Example: Enter 15 and 20.

3) Determine the upper value (as high and constant as possible) with the reference measuring

device.

Example: Increase furnace temperature to 80 °C.

4) Enter the display value as the actual end value and the reference value as the target end

value.

Example: Enter 70 and 80.
