Understanding The Measurement Instructions
When making measurements, follow the numerical steps
labelled in the diagrams. Refer to Table 2- 1 below for a
description of the steps.
Measuring Voltage
The U1251B and U1252B offer true- RMS readings for AC
measurements that are accurate for sine waves, square
waves, triangle waves, staircase waves, and other waveforms
without any DC offset.
For AC with DC offset, use AC + DC measurement on
or rotary switch location. Applies only to U1252B.
