INTRODUCTION
The B & K Precision Model 28318 bench-type3-ll2
digit multimeter is a highly versatile instrument offering
standard functions of voltage, current (with a 20 A range),
and resistancemeasurements.[n addition, it also includes
diode test and continuity functions.
The instrument is easy to use, as all functions are
selectedfrom a panel of very logically laid out and identified
pushbuttons. The 3-ll2 digit LED display features 0.43"'
digits with automaticminus sign and auto-zerocapability.
The unit is housed in a rugged, attractiveplastic case,and the
carrying handle doublesas a sturdy tilt stand.The tilt standcan
be folded on top of the instrument to allow stacking with your
other instrument.
Safety features include safety jacks, safety test leads, and
extensiveoverloadprotection,including a high energy fuse.
B & K Precision offers a full line of optional accessories
for the Model 28318 which can further expand the capabilities
and usefulnessof the instrument. Please contact your locai
B & K Precision distributor or B & K Precision for more
information on the latestaccessories.

The TEST INSTRUMENT SAFETY section
of this manual lists maximum voltage and

Failure to adhere to these limits may result
in damage to the instrument.
PRELIMINARY
Plug the unit into an ac outlet of the appropriatevoltage
and turn it on by depressingthe POWER switch.
4.lf an approximatevoltagerangeis known, simply pressthe
switch for the range desired. Greatestresolution is attained
using the range closest to an over range for the voltage
being measured.
5. Connectthe red test leadto the V-O jack and the black test
lead to the COM jack.
6. Connect the test leads across the circuit noints to be
measured.
7. Read the measuredvalue from the display.
OPERATINGINSTRUCTIONS
CURR E N M
T EA S U R E ME N T S
For current meqsurements,the meter must
be connected in series wilh the load. If
incorrectly connected (in parallel with the
load), the meter presents a very low
impedance (almost a short), which may blow
the fuse or damage the meter or equipment
under test. The 20 A range has on fuse
protection and moy severely damage the
meter or equipment under test or cause
personal injury.
For current meesurementsgreater thun 2 A,
high curent test leads should be used. High
current measurements with standard test
leads could cause the leads to heat up. This
nol only affects the accuracy of the
meqsurement, but could result in injury to
the operator.

be checked.
5. Connectthe test leadsto the desiredmeasruementpoints.

The instrument will then be operating in standard ohms
mode.
5. The display indicates diode forward voltage. Normal diode
voltagesare approximately0.3 V for germaniumdiodes,0.6
V for silicon devices,and 1.6V for light emitting diode (LED's).
An overrange indicates an open diode. A shorted diode reads
near0 V.
6. To checkthe reverse-bias

open test leads (an overrange). A lower reading indicates a

MAINTENANCE
GurrentRangeFuse
Note: The fuse most likely to open first can be inspectedand
changedwithout caseremoval. It is locatedon the rear panel of
the unit. Simply use a flat blade screwdriver to rotate the
terminalcounterclockwise.
The following instructions are for use by
qualified service personnel only. To avoid
electrical shock, de not perform servicing
other than contained in the operating instructions unlessyou are qualified to do so.
Remember that ac line voltage is present on
line voltage input circuits any time the instrument is plugged into an ac outlet, even if
turned off. Always unplug the unit before
perforning servicing procedures.
Then remove the entire assembly,including the fuse. If this fLse is
