HP 3478A Multimeter Quick Reference Guide
This document is designed to cover the most basic operation selections and buttons for
the 3478A Multimeter. This is not a comprehensive listing of functions. Please refer to
the full users manual for functions or questions not covered by this users guide..
The 3478A is a full 6 digit multimeter capable of reading signals from 0.1µV to 300V
peak. The meter is quite flexible in resolution and scaling modes, but also has a lot of
advanced features for communications and programming that we will not cover here.
Display:
The display will indicate the number and range of the reading begin taken. It also has a
number of small indicators along the bottom of the screen to indicate particular modes.
Much of the displayed modes are self explanatory.
Control Buttons:
There are two rows of function buttons located under the display. These buttons control
what is being measured and how it is measured.
The first control to note is the "cal enable" switch to the right. This should NEVER be
turned to the cal position (vertical)
The second thing to note is that some buttons are dual function. Those with dual
functions are labeled by blue lettering above the button. Pressing the blue button places
the keyboard into "shift" mode, indicated by the word 'shift' on the display. IN this
mode the buttons perform the blue functions.
