HP References in this Manual

This manual may contain references to HP or Hewlett-Packard. Please note that
Hewlett-Packard's former test and measurement, semiconductor products and
chemical analysis businesses are now part of Agilent Technologies. We have
made no changes to this manual copy. In other documentation, to reduce
potential confusion, the only change to product numbers and names has been in
the company name prefix: where a product number/name was HP XXXX the
current name/number is now Agilent XXXX. For example, model number
HP8648A is now model number Agilent 8648A.

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
M A 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 11) 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.

Calibration and A djustment

Required Test Equipment

The source used for the calibration should have an output accuracy as good or better than
that listed in the specifications.

Calibration Procedure

Environmental range for calibration: 23° C ± 5° C, < 80% RH
Calibration interval: 1 Year

1 Dis connec t all inputs fr om the multi meter and open the ca se as shown 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 Whe n approp riate, mak e the adjus tments ind icated in th e calibr ation tabl e 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 qualifie d service technicia ns. Use a non- conduc tive adjus tment tool .

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 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. Fuses are listed in the re placeab le
part list on page 6-4. See fuse check pr ocedure i n Troubles hooting tab le below.

CAUTION
For continued protection use only the specified manufacturer part number or HP part number

fuse for replace ment purpos es.
