Making Measurements

Introduction
XW Warning
To avoid possible electrical shock, and/or damage to the Meter,
• Read the safety information found in Chapter 1 before
operating this meter.
• Do not apply more than 1000 volts between any terminal
and earth ground.
This chapter covers the steps for making a measurement with each of the Meter’s
functions. These steps include making a proper and safe connection between the Meter
and the circuit, as well as the manipulation of the front-panel controls to display the
selected measurement.
If you are unfamiliar with the front-panel controls, review the relevant sections in
Chapter 3.
Selecting Function Modifiers
Most of the functions described in this Chapter will have choices for changing how the
measured value is displayed or how the input signal is processed. These “Function
Modifiers” appear in the bottom line of the display as soft key labels. The available
selections are dependent on the selected function and are described in the Meter function
descriptions provided in this Chapter.
Activating the Secondary Display
For most of the Meter’s functions, an additional measured parameter may appear in the
display. These additional parameters are available when 2ND MEAS appears over one
of the soft keys.
The secondary measurement may be another parameter of the primary signal (e.g., ac
voltage and frequency of one signal), or a measurement of another signal made
simultaneously with the primary signal (e.g., dc voltage and dc current).
The range of the secondary display is always automatically controlled.
To select a secondary measurement:
1. Press the soft key labeled 2ND MEAS.
Each additional press of this soft key will cause the secondary display to cycle
through the available measurements. After the last secondary measurement is shown,
the next press of this soft key turns the secondary display off.
Note
When switching between Meter functions, the secondary display selection
for the function you last selected is deactivated the next time that function is
selected.
