Section 7. Measurement Instructions
7.1 Voltage Measurements
VoltDiff (Dest, Reps, Range, DiffChan, RevDiff, SettlingTime, Integ, Mult,
Offset)
Sensor
Diff. Channel H
Diff. Channel L.
This instruction measures the voltage difference between the high and low
inputs of a differential channel. Both the high and low inputs must be within ±
5V of the datalogger's ground (See Common Mode Range, Section 3.2). With
a multiplier of one and an offset of zero, the result is in millivolts or volts
depending on the range selected.
See section 7.2 for parameter descriptions.
VoltSE (Dest, Reps, Range, SEChan, MeasOff, SettlingTime, Integ, Mult,
Offset)
Sensor
S.E. Channel
Ground
This instruction measures the voltage at a single ended input with respect to
ground. With a multiplier of one and an offset of zzero, the result is in
millivolts or volts depending on the range selected.
See section 7.2 for parameter descriptions.
7.2 Thermocouple Measurements
TCDiff (Dest, Reps, Range, DiffChan, TCType, TRef, RevDiff, SettlingTime,
Integ, Mult, Offset)
Diff. Channel H
Diff. Channel L
Thermocouple
This instruction measures a thermocouple with a differential voltage
measurement and calculates the thermocouple temperature (°C) for the
thermocouple type selected. The instruction adds the measured voltage to the
voltage calculated for the reference temperature relative to 0° C, and converts
the combined voltage to temperature in °C. The ranges that are specified with
a code ending in C (e.g., mV20C) briefly (10 µs) connect the differential input
