Trimmer
For adjustment of zero and end value per channel. Only available at versions WTAU – 100 / 200.
At the Pt100 – isolation amplifier WTAU – 200 – U0 both output signals (output 1 and output 2) are changed uniform by the
configuration switches and by the trimmer channel 1.
The output 2 can be additionally separately changed in the zero value by  3% and in the end value by  6% by the further
trimmer at the front side (channel 2).
For an accurate results the adjustment zero value – end value must be proceeded repeatedly with connected signal,
because zero and end value adjustment effects each other.
Configuration switches
The configuration of the input and output signal ranges is made per dip switches inside the housing.
Dangerous voltage
Ensure a safe switching off the supply voltage when opening the housing
For configuration release the upper housing part at top and bottom side behind the terminals by using a screwdriver and pull
it out of the housing. Drop-in pin's avoid a complete pulling out. Following the respective dip switches can be set according to
the desired functions to ON or OFF.
The switch S3 of switcher block S3 must be set to position ON. The position of all other not described switches are without
importance.
