Introduction
Chapter 3 explains how to make measurements.
Most measurement functions can be selected by using the rotary switch.
White letters or symbols identify primary functions; blue letters or symbols identify alternative functions. Press the blue button
to access these alternate functions. Frequency-related functions can be selected when the rotary switch is in any of the
、
or

Voltage is the difference in electrical potential between two points. The polarity of ac (alternating current) voltage varies over
time, while the polarity of direct current voltage is constant over time.
Ranges available in volts functions are:
