Changing the jumpers
Throughout the circuit board there are components which are sensitive to
electrostatic discharges. Explanation will be found in the
Appendix, “Icons” section.
Range selection (PCD3.W610 only)
Jumpers, factory settings A0...A3:
“V”
(voltage)
U/B:
“B”
(bipolar)
Reset select: “mid” (reset to mid scale,
i.e. 0 V in bipolar mode)
Ranges depending on application.
Per module
U/B:
U
nipolar or
B
ipolar mode
Reset select:
Reset to
low
- or
mid
- scale
Recommended setting:
Unipolar → low-scale
Bipolar → mid-scale
Per channel
“V”:
Voltage output:
0...+10 V or -10 V...+10 V
“C”: Current output: 0...20 mA
Current outputs have been laid out for unipolar mode. Bipolar mode is possible, but
for the negative half of this operation the output is 0 mA.
