BK Precision 5492B Instruction Manual
USER MANUAL
Model: 5492B, 5492BGPIB
5 ½ Bench Digital Multimeter
Safety Notice
As described in the International Electrotechnical Commission (IEC) Standard IEC 664, digital
multimeter measuring circuits (e.g., B&K Models 5492B) and the USB terminal are Installation
Category II (CAT II). All other instruments’ signal terminals are Installation Category I and must
not be connected to mains.
This equipment is a POLLUTION DEGREE 2, INDOOR USE product.
Safety Summary
The following safety precautions apply to both operating and maintenance personnel and
must be observed during all phases of operation, service, and repair of this instrument.
Before applying power, follow the installation instructions and become familiar with the
operating instructions for this instrument.
GROUND THE INSTRUMENT
To minimize shock hazard, the instrument chassis and cabinet must be connected to an
electrical ground. This instrument is grounded through the ground conductor of the
supplied, three-conductor ac power cable. The power cable must be plugged into an
approved three-conductor electrical outlet. Do not alter the ground connection. Without the
protective ground connection, all accessible conductive parts (including control knobs) can
render an electric shock. The power jack and mating plug of the power cable meet IEC
safety standards.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Do not operate the instrument in the presence of flammable gases or fumes. Operation of
any electrical instrument in such an environment constitutes a definite safety hazard.
KEEP AWAY FROM LIVE CIRCUITS
Instrument covers must not be removed by operating personnel. Component replacement
and internal adjustments must be made by qualified maintenance personnel. Disconnect the
power cord before removing the instrument covers and replacing components. Under certain
conditions, even with the power cable removed, dangerous voltages may exist. To avoid
injuries, always disconnect power and discharge circuits before touching them.
DO NOT SERVICE OR ADJUST ALONE
Do not attempt any internal service or adjustment unless another person, capable of
rendering first aid and resuscitation, is present.
DO NOT SUBSTITUTE PARTS OR MODIFY THE INSTRUMENT

Chapter 1 General Information
This chapter is outlined as follows:
1.1 Feature Overview
1.2 Input Power and Fuse Requirements
1.3 Package Contents
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 volt age 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 corres pon ds to t he li ne volt age t o be used f or op eratio n. Note the l abe l in the r ear labe l,
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 insi de the fuse box. Referring to the above table, use a 1
A fuse for 110 V/ 60 Hz operation, an d 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 o f the fuse
box that indicates the selected line voltage. To c hange or select the appropriate line voltage,
remove the fuse box and pul l out and rotate the fuse holder, as illustrated below:

Fuse Box
There is a second fuse with a fuse holder located in the front panel of the multimeter. This is an over
current protection fuse for the low current measurement input. It is rated for a T2AL, 250 V fuse. To
remove and replace this fuse, see the illustration below:
To remove, use a flat head screw driver or a coin to
insert into the slid and turn counter-clockwise to
open. Similarly to put back the fuse box, push the
box down and turn clockwise.
110
There is a third fuse locat ed ins ide the instrument which prot ects the 12 A input terminal if current
exceeds the maximum rat i ng. It is a 6 x 32 mm 250V, 20 A fast acting high energy ceramic fuse.
