Chapter 3 Basic Measurements
This chapter is outlined as follows:
3.1 Overview
3.2 Measuring Voltage
3.3 Measuring Current
3.4 Measuring Resistance
3.5 Measuring Frequency and Period
3.6 Measuring Continuity
3.7 Testing Diode
3.8 Math Functions
3.1 Overview
The front panel has two rows of keys to select various functions and operations. Most keys have a
shifted function printed in blue above the key. To perform a shifted function, press (the Shift
annunciator will turn on). Then, press the key that has the desired label above it. For example, to select
the AC current function, press then press (AC I).
If you accidentally press , just press it again to turn off the Shift annunciator.
3.2 Measuring Voltage
Voltage ranges: 120 mV, 1.2 V, 12 V, 120 V, 1000 V (750 VAC)
Maximum resolution: 1 μV (on 120 mV range)
3.2.1 Connections
Assuming the multimeter is under factory default conditions, the basic procedure for measuring voltage
is as follows:
1. Connect test leads to INPUT HI and LO terminals.
2. Select DC or AC voltage measurement by pressing or respectively.
3. Press to toggle between auto and manual ranging. Notice the AUTO annunciator is
displayed with auto ranging. For manual range, use the RANGE and keys to select
the appropriate range for measurement.
4. Connect test leads to the sources as shown in Figure 3-1.
CAUTION: Do not apply more than 1000 V peak to the input or it will damage the instrument.
5. If the “OVR.FLW” message is displayed, press the up key to select a higher range until a
normal reading is displayed (or press key for auto ranging). Use the lowest possible range for
the best resolution. The measured reading is displayed.
