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 Ω (may be changed to 10G Ω ! for 100 mV, 1 V, & 10

V DC ranges)
