How to Make Measurements
The following sections describe how to make
measurements with the Meter.
AC and DC Voltage Measurements
Model 28 II features true-rms readings, which are
accurate for distorted sine waves and other waveforms
(with no dc offset) such as square waves, triangle waves,
and staircase waves.
The Meter’s voltage ranges are 600.0 mV, 6.000 V,
60.00 V, 600.0 V, and 1000 V. The select the 600.0 mV
dc range, turn the rotary switch to mV.
Refer to Figure 2 to measure ac or dc voltage.
