1.1 Feature Overview
5492B is a 5½ digital multimeter with high accuracy, stability and speed. It has a 0.01% DC voltage
basic accuracy, 0.03% basic resistance accuracy and broad ranges that can measure:
 DC voltage up to 1000 V
 AC (RMS) voltage up to 750 V, or about 1000 V Peak
 DC current up to 12 A
 AC (RMS) current up to 12 A
 Two and four-wire resistance up to 120 MΩ
 Frequency from 5 Hz to 1 MHz
1.2 Input Power and Fuse Requirements
The 5492B digital multimeter can operate on 110 V or 220 V with +/- 10% tolerance at 60 Hz or 50 Hz
with +/- 5% tolerance respectively. Before powering the instrument, please check for correct power
input setup that corresponds to the line voltage to be used for operation. Note the label in the rear label,
as shown below:
RATING FUSE
~110 V / 60 Hz T1AL, 250 V
~220 V / 50 Hz T500mAL, 250 V
There are two items to check for:
1. Check that the correct fuse is placed inside the fuse box. Referring to the above table, use a 1
A fuse for 110 V/ 60 Hz operation, and 500 mA fuse for 220 V/50 Hz operation.
2. Check the fuse holder position. There is a voltage indicator window on the front face of the fuse
box that indicates the selected line voltage. To change or select the appropriate line voltage,
remove the fuse box and pull out and rotate the fuse holder, as illustrated below:
