With reference to the figure Programmable Gain Input Amplifier (PGIA)
(p. 420),
during a single-ended measurement, the high signal (H) is routed to V+. The low
signal (L) is automatically connected internally to signal ground with the low
signal tied to ground ( ) at the wiring panel. V+ corresponds to odd or even
numbered U terminals on the CR6 wiring panel. The single-ended configuration
is used with the following CRBasic instructions:
•
VoltSE()
• BrHalf()
•
BrHalf3W()
•
TCSE()
• Therm107()
•
Therm108()
•
Therm109()
• Thermistor()

Using the figure Programmable Gain Input Amplifier (PGIA)
(p. 420),
for reference,
during a differential measurement, the high signal (H) is routed to V+ and the low
signal (L) is routed to V–.
The odd member of a U terminal pair corresponds to V+. The even member
corresponds to V–. The differential configuration is used with the following
CRBasic instructions:
• VoltDiff()
•
BrFull()
•
BrFull6W()
• BrHalf4W()
•
TCDiff()
