Section 3: Basic Measurement Functions Model 2100 6 1/2-Digit Resolution Digital Multimeter User’s Manual
Introduction
This section introduces some basic measurement functions of the Keithley Instruments Model
2100 6 1/2-Digit Resolution Digital Multimeter
®
. You will learn how to use the Model 2100
multimeter to measure voltage, current, resistance, frequency, period, continuity, and diode
forward voltage.
Voltage measurements (DC and AC)
The ranges for DC voltage (DCV) measurements for the Model 2100 are 100mV, 1V, 10V, 100V,
and 1000V. For AC voltage (ACV) measurements, the ranges are 100mV to 750V RMS, or 1000V
peak.
Figures 3-1 and 3-2 show the locations of the keys needed and message displays 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 Model 2100 multimeter. Applying
excess voltage may damage your meter or cause possible electric shock,
resulting in personal injury or death.
NOTE To eliminate the thermal EMFs due to the differences between two metals, use copper
leads to connect your source signal to the meter.
