Congratulations! You are now the owner of an AMPROBE®
instrument. It has been quality crafted according to quality
standards and contains quality components and workman¬
ship. This instrument has been inspected for proper opera¬
tion of all of its functions. It has been tested by qualified
factory technicians according to the long-established

with or taken apart.
Should your Instrument fall due to defective materials, and/or
workmanship during the one-year warranty period, return it
along with a copy of your dated bill of sale which must iden¬
tify instrument by model number and Mfg. number.
For your protection, please use the instrument as soon as
possible. If damaged, or should the need arise to return
your instrument, it must be securely wrapped (to prevent

stated or implied.
PRECAUTIONS FOR PERSONAL
AND INSTRUMENT SAFETY
IMPORTANT:
1. Read these instructions thoroughly and follow
them carefully.
2. In many instances you will be working with
dangerous levels of voltage and/or current,
therefore, it is important you avoid direct contact
with any uninsulated, current-carrying surfaces.
Appropriate
insulating
gloves
and
clothing
should be worn.
3. Before connecting or disconnecting the voltmeter
to or from the circuit to be tested, turn off all
power to the circuit.
4. Before applying test leads to circuit under test,
make certain that leads are plugged into proper
jacks and switches are set to proper range and
function.
5. Before using any electrical instruments or tester
for actual testing, the unit should be checked on a
low energy high impedance source. Do not use
power distribution lines or any other high energy
sources.
6. Make certain no voltage is present in circuit,
before connecting ohmmeter to circuit.
7. The jaws of clamp-on instruments should not,
under any circumstances, be used as a device to
hold or hang the instrument. When using the
instrument as a voltmeter or ohmmeter, never
clamp the jaws around or on to a conductor box or
anything else — conducting or non-conducting.
Models FS-3, FS-3C are supplied with a set of test leads
(VL-11S) and an 0.5 Amp fuse. Temperature Probes and
other accessories are available separately.
The Flat Scale Clamp-Ons FS-3, FS-3C are capable of
measuring Volts, Amps, Ohms and Temperature. By turn¬
ing the rotary switch to the particular area, any one of these
functions can be selected. No separate attachment is
necessary for ohms. Temperature measurements can easi¬
ly be made by inserting probe in side of instrument housing.
Refer to individual instructions for each function.
The ohmmeter of the FS-3, FS-3C uses an "AA" battery
and an 0.5 amp 250 volt fuse. To replace either fuse or bat¬
tery remove two screws on back case, slide case horizon¬
tally toward you and lift off. See Fig. 2. Replace with cor¬
rect fuse. See page 6. Observe proper polarity when
replacing battery.

How to Take
CURRENT READINGS
1. Make certain meter lock is in off position. See Fig. 1.
Meter is free when button is pushed to the far right.
2. Make sure pointer is reading zero. For greater ac¬
curacy, the pointer should be set on the zero line. This
is done by manually moving the zero adjust screw. See
Fig. 1.
3. Turn rotary switch to highest current range if current to
be measured is unknown.
4. Press trigger to open jaws.
5. Encircle conductor with transformer jaws.
6. Release trigger and be sure that jaws close properly
before taking reading.
7. If reading is below half scale, move rotary switch to the
next lower range. Keep moving rotary switch to lower
ranges until pointer is indicating in the upper half of
the scale.
How to Take
VOLTAGE READINGS
IMPORTANT
Read "PRECAUTIONS FOR PERSONAL AND
INSTRUMENT SAFETY" before using instrument.
1. Insert bayonet type voltage test leads into voltage
receptacles at bottom of instrument. Push against
receptacle spring and twist to lock in place. See Fig. 3.
2. Turn rotary switch to highest voltage range if voltage
to be measured is unknown.
3. Connect one alligator clip to one side of voltage to be
measured. Then with meter in one hand touch the
other side of voltage source with other lead. If reading
is below half scale move rotary switch to the next
lower range. Keep moving rotary switch to lower
ranges until pointer is indicating in the upper half of
the scale.
