4- or 8-wire
sensor cable
Jumpers W2 and W3 establish the correct shunt calibration connections
for 4-wire and 8-wire sensor cables. The length of the sensor cable
determines which type of cable is used. Short cables are typically 4-
wire cables while long cables are typically 8-wire cables.
• Jumper W2 selects a 4- or 8-wire transducer for positive feedback.
• Jumper W3 selects a 4- or 8-wire transducer for negative feedback.
• The setting of jumper W8 (single ended excitation enable) may
affect your choices for these jumpers (W2 and W3).
Note +/– excitation (–excitation is standard). See XDCR ID-W1.
Bridge balance Jumper W4 changes the offset of the bridge balance circuit. If the zero
offset is too large when the sensor bridge is balanced, you should
enable this feature (it adds a 100 kΩ resistor to the input of the
conditioner preamp).
