Note
During a scan, a channel set up with autoranging will momentarily slow
the scanning rate whenever the correct range must be determined. This will
occur during the initial scan, with the instrument remembering the range
for subsequent scans. Scans then occur at the normal measurement rate. If
the input signal later changes sufficiently, the scanning rate will again
slow momentarily while the instrument determines the new range.
AC voltage measurements can be made over a wide range of frequencies. The
instrument’s true rms converter insures accuracy for both sine wave and non-sine wave
signals. Refer to Chapter 5 for additional information about true rms measurements.
Resistance measurements can be made to determine either resistance or the value of
another directly related parameter. Slide wire potentiometers, thermistors, and other
sensors with variable resistance outputs are often used to indicate temperature, position,
and other physical parameters. The instrument measures resistance by passing a current
