Description
Auto Zero provides the most accurate measurements, but requires additional measurement time to perform
the zero measurement. With auto zero enabled (
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. With auto zero
Off ), the instrument measures the offset once and subtracts the offset from all subsequent
disabled (
measurements. The instrument takes a new offset measurement each time you change the function, range,
or integration time. (There is no auto zero setting for 4-wire measurements).
This setting is available when Scan or DMM Digitize is selected as the
acquisition mode.
Specifies the measurement terminal input impedance, which is either 10 MΩ (
(
Auto ). The Auto mode selects high impedance (> 10 GΩ) for the 100 mV, 1 V, and 10 V ranges, and 10 MΩ
for the 100 V and 300 V ranges. In most situations, 10 MΩ is high enough to not load most circuits, but low
enough to make readings suitable for high impedance circuits. It also leads to readings with less noise than
the high impedance option, which is included for situations where the 10 MΩ load is significant.
This setting is available when Scan or DMM Digitize is selected as the
acquisition mode.
Selects whether the delay between channels in the scan list will be automatically or manually selected. By
Auto , instrument will automatically determine the channel delay based on measurement function,
selecting
range, integration time, and AC filter setting. By selecting
inserted between the relay closure and the actual measurement on each channel, in addition to any delay
that will implicitly occur due to relay settling time.
This setting is only available when Scan is selected as the acquisition mode.
