Excepts from: ”An Introduction to Using the Agilent 54622D Digital Oscilloscope, E3631A DC Power
Supply, 34401A Digital Multimeter, and 33220A Arbitrary Waveform Generator

Part Four - The Agilent 34401A Digital Multimeter
1. Measuring DC and AC Voltage
2. Measuring Resistance
3. Measuring Current
Part Four – The Agilent 34401A Digital Multimeter
The DMM (digital multimeter) is a very important laboratory instrument. This
section will show you how to make three of the basic measurements: voltage,
resistance and current. The 34401A has many capabilities beyond measuring V,
R and I; consult the Agilent User's Guide for information on measuring frequency,
period, continuity & diodes, and using the many features and functions of this
DMM.
When you turn the DMM on, it will be in the "Power-On and Reset State":
Function = DC volts
Input resistance = 10M (may be changed to 10G ! for 100 mV, 1 V, & 10
V DC ranges)

Strona 2

Range = Autorange Resolution = 5½ digits Measuring DC and AC Voltage Key points: ¾ You must insert the voltmeter leads across the two points

Strona 3

Measuring Resistance Key points: ¾ NEVER measure resistance in a "live" circuit. Turn off all power to the circuit.

Strona 4

¾ See User's Guide page 216 for the test current for each resistance range. Measuring Current Key points: ¾ You must insert the ammeter leads
