Basic Measurement Function

This chapter introduces some basic measurement functions in M3500A.
You will learn how to use your M3500A multimeter to measure voltage,
current, resistance,
temperature in this chapter.
3.1 Voltage Measurements (DC & AC)
The ranges for DC voltage measurements in M3500A are 100mV, 1V,
10V, 100V and 1000V. For AC voltage measurements, the ranges are
100mV to 750V AC-Coupled
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.
