3. Inspect the Multimeter before
use. In addition to a general
inspection, look specifically for:
a. Pay special attention to the
insulation protecting the connectors.
b. Check the leads for exposed metal,
damaged insulation, and continuity.
c. Replace damaged test lead
immediately, before use.
4. Do not use the Multimeter if:
a. Either of the test leads are
damaged in any way.
b. Test leads are dirty or
have residue on them.
c. The battery is low.
d. Near any explosive
gasses or fumes.
e. Any abnormal operation is
detected.
(If in doubt about the
condition of the Meter, have
it serviced before use.)
f. The battery cover is open.
5. Power this Meter using only
the battery(ies) referenced in
the Specifications Chart.
6. Use caution when working near
voltages above 30 VAC rms, 42 VAC
peak, or 60 VDC. Voltages this high
present a risk of electric shock.
7. Disconnect the circuit’s power
before connecting the Meter in
series, when measuring current.
8. Connect the common (COM) test
lead first and disconnect it last.
9. Hold the probes with fingers
behind guards.
10. Avoid electrical shock. Use extreme
caution when working near uninsulated
conductors or bus bars. Prevent body
contact with grounded surfaces such
as pipes, radiators, ranges, and cabinet
enclosures when testing voltages.
11. Observe work area conditions. Do
not test voltages in damp or wet
locations. Don’t expose to rain.
Keep work area clean and well lit.
12. Keep children away. Children must
never be allowed in the work area.
13. Stay alert. Watch what you are doing,
use common sense. Do not operate
any meter when you are tired.
14. Do not operate meter if under the
influence of alcohol or drugs. Read
warning labels on prescriptions to
determine if your judgment or reflexes
are impaired while taking drugs. If there
is any doubt, do not operate the meter.

15. People with pacemakers should
consult their physician(s) before use.
Electromagnetic fields in close
proximity to heart pacemaker could
cause pacemaker interference
or pacemaker failure.
16. Do not test voltage on circuits
higher than 1000 volts.
17. Do not test current on circuits
higher than 10 amps.
18. Dress properly. Protective,
electrically nonconductive
clothes and nonskid footwear are
recommended when working.
19. Wear ANSI-approved safety
goggles during use.
20. Only use accessories intended
for use with this meter.
21. Avoid damaging meter. Use only
as specified in this manual.
22. Prior to testing resistance, diodes,
or continuity; disconnect all power
to the circuit and discharge all
high-voltage capacitors.
23. Performance of this meter may vary
depending on battery condition.
24. Use the proper settings, terminals,
techniques, and range for the
tests performed. Start with the
range stated in the instructions.
25. Do not apply voltage to the
Test Leads when the Multimeter
is in the Ohms testing setting.
Damage can occur to the Meter.
26. Do not switch between testing
modes with the multimeter
connected to a circuit.
27. Do not use the meter at a setting
marked as blank on the scale.
28. Have the Multimeter calibrated by
a qualified technician every year
to maintain accurate results.
29. Do not disassemble charger;
take it to a qualified technician
when service or repair is required.
Incorrect reassembly may result
in a risk of electric shock or fire.
30. The warnings, cautions, and
instructions discussed in this
instruction manual cannot cover all
possible conditions and situations
that may occur. It must be understood
by the operator that common sense
and caution are factors which cannot
be built into this product, but must
be supplied by the operator.

KFMR6%S'$$&8
The KFMR6 Button enables manual selection of available ranges for the selected
function. The Meter’s default is F'$&(,83*%]FPGI^%where the Meter selects for you1
1. To select manual ranging mode, hold
down KFMR6%Button until the Meter
beeps. The Meter is in manual mode
when NFMP is seen on the Display.
2. Each press of the KFMR6 Button
steps through the ranges available
for the selected function.
3. To return to Autorange, hold down
the KFMR6 Button for about 2
seconds or until the Meter beeps.
The Meter is in Autorange when
FPGI is seen on the Display.
NF`%NLM%S'$$&8
The NF`%NLM Button allows you to record, temporarily store and
view signal events as you monitor them. You may record while in
any range or mode except Hz% (frequency/duty cycle).
1. Press the NF`%NLM (maximum/
minimum) Button to begin
recording. Note that the Meter
automatically resets to manual
range mode when measuring
minimum / maximum values.
2. When you are finished recording,
press the NF`%NLM Button to scroll
through the high (maximum) and low
(minimum) recorded readings. The
readings will be seen on the Display.
3. To return to normal operating
mode, hold down the NF`%NLM
Button for about 2 seconds.
K6T% %S'$$&8
The K6T (relative mode) Button can be used in all modes except Hz%
(frequency/duty cycle). Relative mode subtracts a stored value from the present
measurement and displays the result. For example, if the stored value is 20.0V
and the present measurement is 22.0V then the Meter will display 2.0V.
1. To enter relative mode, press the
K6T Button. The present
measurement will lock and
the Meter will display “0”.
2. Take a new measurement and the
Meter will display the relative value.
3. Press the K6T Button again to reset
the stored value and exit relative mode.

X\a%S'$$&8
The X\a (frequency/duty cycle) Button allows you to measure the frequency
and duty cycle (the ratio of time a load or circuit is on verses off) of a signal.
1. To measure the frequency/duty cycle,
press the X\a Button. Frequency (Hz)
is the default measurement mode.
2. To measure U'$V%OV47*,
press the X\a Button again
to select a measurement.
3. To exit the frequency/duty
cycle measuring mode,
press the X\a Button.
XITU%0%TLRXG%S'$$&8
The XITU0TLRXG Button has two functions: To hold the present
reading on the Display and to turn on the Display’s backlight.
1. To activate XITU, hold down the
XITU0TLRXG Button until the
meter beeps and the %symbol
appears on the Display.
2. When in XITU mode, the present
reading will be held on the Display.
3. To exit HOLD, hold down the
XITU0TLRXG Button until the
meter beeps and the %symbol
disappears from the Display.
M&$*- The Hold mode will not capture
unstable or noisy readings.
4. To turn on the Display’s backlight,
hold down the XITU0TLRXG
Button for about 2 seconds.
5. The backlight will automatically
turn off after about 10 seconds.
M&$*- Frequent use of the backlight
shortens the life of the battery(ies). Only
use the backlight when necessary.
S7'*%S'$$&8
The Blue Button is used to enable available modes for a selection on the Rotary Switch.
F'$&%J&)*(?I22% %,89%E7**/%N&9*%
If the Meter is not used for approximately 15 minutes, it automatically
turns itself off to conserve battery power. The Meter’s default is enabled
F'$&%J&)*(?I22%which is indicated by appearing on the Display.
1. E7**/%N&9* is active when
is seen on the display.
2. To turn the Meter back on after
auto power-off, press any Button
or turn the Rotary Switch.
3. To disable F'$&%J&)*(?I22, hold down
the S7'* Button while turning on the
Meter. The symbol will not display
when Auto Power-Off is disabled.
S,(%R(,/.
The bar graph updates faster than the digital display. This can be used
for monitoring changes in measurements at a higher sampling rate.
The bar graph indicates polarity (?) and overload ( IT).
