The procedure for setting thresholds is identical for both switching functions.
 Put the gauge into operation.
 Connect the + lead of a voltmeter to the threshold measurement point of the
selected switching function ("Setpoint A" Pin 3, "Setpoint B" Pin 6) and
its
– lead to Pin 5.

 Using a screwdriver (max. ø2.5 mm), set the voltage of the selected
switching function (Setpoint A, B) to the desired value U
Threshold
.
On the BPG400-SR, threshold potentiometer settings ≤0.5 V are
ignored, threshold values defined via RS485 will be effective in-
stead (
→  42).
Setting of the switching functions is now concluded.
There is no local visual indication of the statuses of the switching func-
tions. However, a functional check of the switching functions (On/Off)
can be made with one of the following methods:
• Reading the status via fieldbus interface →  [1] for BPG400-SD,
→  [2] for BPG400-SP, →  41 for BPG400-SR.
• Measurement of the relay contacts at the sensor cable connector
with a ohmmeter/continuity checker (
→  21).
