Function
This chapter introduces some basic measurement functions in
ATM3500A. You will learn how to use your ATM3500A multimeter to
measure voltage, current, resistance, frequency, period, continuity,
diode and temperature in this chapter.
3.1 Voltage Measurements (DC & AC)
The ranges for DC voltage measurements in ATM3500A are 100mV, 1V,
10V, 100V and 1000V. For AC voltage measurements, the ranges are
100mV to 750V AC-Coupled
TRMS
, or 1000V peak.
Figures 3-1
and

show the locations of the buttons needed and message display for
voltage measurement.
Figure 3-3
shows the location of the input
terminals on the rear panel.
Warning: Do not apply more than 1000V (peak) to the
multimeter. Applying excess voltage may damage your meter, or cause
possible electric shock or personal injury.
※
Note: To eliminate the thermal EMFs due to the differences between
two metals, use copper leads to connect your source signal to the
meter.
How to measure voltage
1
Selects input signal connections on front or rear
panel.
2
Connect the test leads to the terminals as shown in
Figure 3-1
(DC)
or
Figure 3-2
(AC).
