numbered SE terminals on the CR1000 wiring panel. The single-ended
configuration is used with the following CRBasic instructions:
• VoltSE()
• BrHalf()
• BrHalf3W()
• TCSE()
• Therm107()
• Therm108()

Differential Measurements — Details
Using the figure Programmable Gain Input Amplifier (PGIA)
(p. 306), for reference,
during a differential measurement, the high signal (H) is routed to V+ and the low
signal (L) is routed to V–.
An H terminal of an H/L terminal pair differential corresponds to V+. The L
terminal corresponds to V–. The differential configuration is used with the
following CRBasic instructions:
• VoltDiff()
• BrFull()
• BrFull6W()
• BrHalf4W()
• TCDiff()
8.1.2.1.2 Voltage Measurement Limitations
Caution Sustained voltages in excess of ±8.6 V applied to terminals configured
for analog input can temporarily corrupt all analog measurements.
Warning Sustained voltages in excess of ±16 V applied to terminals configured
for analog input will damage CR1000 circuitry.

In general, use the smallest fixed-input range that accommodates the full-scale
output of the sensor. This results in the best measurement accuracy and resolution.
The CR6 has fixed input ranges for voltage measurements and an auto-range to
automatically determine the appropriate input voltage range for a given
measurement. The table Analog Voltage Input Ranges and Options
(p. 309) lists
these input ranges and codes.
