Description
Auto Zero provides the most accurate measurements, but requires additional measurement time to
perform the zero measurement. With auto zero enabled (
offset following each measurement. It then subtracts that measurement from the preceding reading. This
prevents offset voltages present on the instrument's input circuitry from affecting measurement accuracy.
Off ), the instrument measures the offset once and subtracts the offset from all
With auto zero disabled (
subsequent measurements. The instrument takes a new offset measurement each time you change the
function, range, or integration time.
Thermocouple measurements require a reference junction temperature. You can input a known fixed
reference junction temperature (typically used for external reference junctions), use the internally
measured temperature on the module as the reference junction temperature, or use the external
thermistor or RTD measurement. Selects the reference junction source as
The External softkey option is not available when DMM Digitize is selected
as the acquisition mode.
Enables (On) or disables (Off) the thermocouple check feature to verify that the thermocouples are
properly connected for measurements. When enabled, the instrument performs a resistance
measurement with each temperature to check for an open circuit. If one is detected, the result will be
shown as +Overload. If this check is not performed, measurement of an open circuit can produce a
voltage reading near zero resulting in an invalid temperature reading.
This setting is only available when Scan is selected as the acquisition mode.
