Safety Summary

The CAUTIONS and WARNINGS which appear on the following pages must be followed to

ensure operator safety and to retain the operating condition of the Multimeter.

1. Do not use this product beyond its specifications or for uses not intended for this product

as identified by the product functions, ranges, and hazards as indicted below.

2. To minimize possible electric shock hazard condition, connect only two leads at any one

time to any of the multimeter terminals.

3. To prevent possible electric shock hazard condition when using the current function, do not

leave one probe connected to the circuit under test and the other probe disconnected,

exposed, and readily accessible (touchable).

Safety Symbols

Indicates the operator must refer to an explanation in this manual.

Indicates terminals at which dangerous voltages may exist.

WARNING

TO AVOID ELECTRICAL SHOCK or damage to the multimeter, do not apply more than

±1000 Vdc or 1000 Vrms between any terminal and earth ground. Use caution when working with

voltages above 60 Vdc or 42 Vpeak. Ensure test leads are in good condition.

WARNING

POSSIBLE ELECTRICAL SHOCK. Do not make measurements if the case is damaged or the

rear cover is removed. Remove all electrical inputs before removing the rear cover.

WARNING

POSSIBLE ELECTRICAL SHOCK or FIRE HAZARD. Do not expose this multimeter to rain or

moisture. Do not operate the multimeter in the presence of flammable gases or fumes.

Safety Summary

WARNING

POSSIBLE ELECTRICAL SHOCK. Calibration and performance tests are to be performed by

qualified personnel only. Do not attempt calibration or test procedures unless qualified to do so.

CAUTION

To avoid damage to the multimeter for inputs above 250 Vdc or Vac, disconnect the test leads

before changing functions. Do not exceed the maximum input limits.

Maximum Overvoltage Limitations (AC and DC Voltage Functions)

1000V

MAX indicates the maximum voltage between input terminals and earth is ± 1000 V (dc or ac rms).

Do not use the multimeter on any ACV circuit where the maximum impulse overvoltage may

be more than 4000Vpk or any DCV circuit where the maximum impulse overvoltage may be

more than 2500Vpk between the COM and VOLT terminals. Excessive impulse overvoltage

can damage the multimeter voltage functions. Do not measure branch circuits (CAT II) over

600V to earth or service panel circuits (CAT III) over 300V to earth.

Probes and Test Leads

1. Always inspect probes before use. Do not use test leads whose insulation has cuts,

cracks, or other damage that may result in reduced electric shock protection.

2. Keep insulation surface clean between the probe tip connector and the finger guards.

3. If probes other than the ones specified are to be used with the multimeter, be sure the

probes and their leads are rated for the voltage and current to which they will be subjected.

Do not exceed the voltage ratings for the multimeter.

4. Probes supplied with this multimeter are rated for use up to 1000Vrms or Vdc.

Maintenance

Operator protection from electric shock hazard is provided by a double insulated enclosure.

Refer to pages 1-4 and 1-5 for maximum voltage specifications. When servicing, use only

specified replacement parts.

Battery Replacement

Replace the battery when the symbol appears in the display or before calibration. Replace

both batteries at the same time. Use high-quality type AA alkaline (IEC LR6) batteries.

Remove the batteries if the multimeter is to be stored for extended periods of time. Refer to

the disassembly drawing on page 6-5.

Fuse Replacement

Fuse locations are shown in the diagram on page 6-5. Fuses are listed in the replaceable part

list on page 6-4.

Warranty/Service

Limited 3 Year Warranty

What is Covered

The HP 974A Multimeter is warranted by Hewlett-Packard against defects in materials and

workmanship for three years from the date of original purchase. If you sell your unit or give it as

a gift, the warranty is automatically transferred to the new owner and remains in effect for the

original three year period. During the warranty period, we will repair, or at our option, replace at

no charge, a product that proves to be defective, provided you return the product, shipping

prepaid, to a Hewlett-Packard service center.

What is Not Covered

This warranty does not apply if the product has been damaged by accident of misuse or as the

result of service or modification by other than an authorized Hewlett-Packard service center.

No other express warranty is given. The repair or replacement of a product is your exclusive

remedy. ANY OTHER IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS IS LIMITED

TO THE THREE YEAR DURATION OF THIS WRITTEN WARRANTY. Some states, provinces, or

countries do not allow the exclusion or limitation or incidental or consequential damages, so the

above limitation or exclusion may not apply to you.

The warranty gives you specific legal rights, and you may also have other rights which vary

from state to state, province to province, or country to country.

Service

Hewlett-Packard maintains service centers in many countries throughout the world. You may

have your unit repaired at a Hewlett-Packard service center any time it needs service, whether

the unit is under warranty or not. There is a charge for repairs after the warranty period. Repair

or replacement during the first 30 days after purchase will be provided by the sales channel.

After 30 days, contact the nearest service office.

Hewlett-Packard products normally are repaired and reshipped within five (5) working days of

receipt at any service center. This is an average time and could possibly vary depending upon

the time of year and work load at the service center. The total time you are without your unit will

depend largely on the shipping time.
