Safety Summary
The CAUTIONS and WARNINGS w hich appe ar on the followi ng p ages mu st b e foll owed t o
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 th e prod uct fu nctions , rang es, an d ha zard s as i ndicte d be low.
2. To minimize po ssible el ectric shoc k hazard condition , connect on ly two leads at any one
time to any of the multimeter terminals.
3. To prevent po ssible el ectric shoc k hazard condition when using the curre nt function , do not
leave one probe connected to the circuit under test and the other probe disconnected,
exposed, and rea dily acces sible (tou chab le).
Safety Symbols
Indicates the operator must refer to an explanation in this manual.
Indicates term inals at whic h danger ous volta ges may exis t.
WARNING
TO AVOID ELECTRICAL SHOCK or damage to the multi meter, do n ot app ly mor e th an
±100 0 Vdc or 100 0 Vrms betwee n any termi nal and ea rth ground . Use cauti on when wo rking with
voltages a bove 6 0 Vd c or 4 2 Vp eak. E nsure test lead s ar e in good condi tion .
WARNING
POSSIBLE EL ECTR ICAL SH OCK. Do not make meas ureme nts if the case is d amage d or the
rear cover is removed. Remove all electrical inputs before removing the rear cover.
WARNING
POSSIBLE EL ECTR ICAL SH OCK. Ca libr ation and per forma nce te sts ar e to be pe rfor med b y
qualified personnel only. Do not attempt calibration or test procedures unless qualified to do so.
CAUTION
To avoid damage to the multimete r for inputs ab ove 250 Vdc or Vac, disconnec t the test leads
before changing functions. Do not exceed the maximum input limits.
Maximum Overvoltage Limitations (AC and DC Voltage Functions)
1000V
MA X indicates the maxi mu m volt ag e betw ee n inp ut termi na ls an d eart h is ± 1000 V (dc or ac rms).
Do not use the multimeter on any ACV circuit where the maximum impulse overvoltage may
be more tha n 40 00Vpk or a ny D CV circ uit w here t he ma ximu m imp uls e over volta ge ma y 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 servic e panel circ uits (CAT III) over 30 0V to earth.

Probes and Test Leads
1. Always inspect probes before use. Do not use test leads whose insulation has cuts,
cracks, or o ther d ama ge tha t may res ult in red uced elec tric sh ock protec tion.
2. Keep insulation surface clean between the probe tip connector and the finger guards.
3. If probes other than th e ones specif ied are to be use d with the mult imeter, 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.

that listed in the specifications.
Calibration Procedure
Environmental range for calibration: 23° C ± 5 ° C, < 80% RH
Calibration i nterv al: 6 M onths
1 Disconnect all inputs from the multimeter and open the case as described on page 6-5.
2 Install new batteries (described below) and close the cover. Turn the multimeter on and allow a
30 minute warm-up. Open the case.
3 Set the multimeter function and range and the source output to the values specified at each step
in the calibrat ion table on page 6-2.
4 When approp riate, mak e the adjus tments ind icated in th e calibr ation tab le to bring th e multimet er
display within the limits.
CAUTION
Dangerous voltages are present during the calibration procedure. Calibration should only be
performed by qualified service technicians Use a non-conductive adjustment tool.

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 repl acemen t 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 disassembl y dra wing on p age 6- 5.
Fuse Replacement
Fuse locations are sh own in the dia gram on pag e 6-5. Fuse s are listed in the replacea ble part
list on page 6-4.
CAUTION
For continued protection use only the specified manufacturers part number or HP part number
fuse for replace ment purpos es.

Limited 3 Year Warranty
What is Covered
The HP 974A Multimeter is warranted by Hewlet t-Packard against defects i n material s and
workmanship for three years from the date of original purchase. If you sell your unit or give i t as

What is Not Covered
This warranty does not apply if the product has been dam aged by accident of misuse or as the
result of service or modification by other than an aut horized 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 l imit ation or i ncidental or consequential damages, so the
above limitation or exclusion m ay 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 count ry 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 peri od. 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 t ime.
