INSTRUCTION MANUAL
SAFETY INFORMATION
The following safety information must be observed to insure
maximum personal safety during the operation of this meter:
Do not use the meter if the meter or test leads look
damaged, or if you suspect that the meter is not operating
properly.
ever ground yourself when taking electrical measurements.
Do not touch exposed metal pipes, outlets, fixtures, etc.,
which might be at ground potential. Keep your body isolated
from ground by using dry clothing, rubber shoes, rubber
mats, or any approved insulating material.
Turn off power to the circuit under test before cutting,
unsoldering, or breaking the circuit. Small amounts of
current can be dangerous.
Use caution when working above 60V dc or 30V ac rms.
Such voltages pose a shock hazard.
When using the probes, keep your fingers behind the finger
guards on the probes.
Measuring voltages which exceed the limits of the
multimeter may damage the meter and expose the operator
to a shock hazard. Always recognize the meter voltage
limits as stated on the front of the meter.

the Operating Instructions to avoid personal
injury or damage to the meter.
This WARNING symbol indicates a
potentially hazardous situation, which if not
avoided, could result in death or serious
injury.
This CAUTION symbol indicates a potentially
hazardous situation, which if not avoided,
may result in damage to the product.
This symbol advises the user that the
terminal(s) so marked must not be connected
to a circuit point at which the voltage with
respect to earth ground exceeds (in this
case) 500 VAC or VDC.
This symbol adjacent to one or more
terminals identifies them as being associated
with ranges that may, in normal use, be
subjected to particularly hazardous voltages.
For maximum safety, the meter and its test
leads should not be handled when these
terminals are energized.

OPERATION
WARNING: Risk of electrocution. High-voltage circuits,
both AC and DC, are very dangerous and should be
measured with great care.
1. ALWAYS turn the function switch to the OFF position
when the meter is not in use. This meter has Auto OFF that
automatically shuts the meter OFF if 15 minutes elapse
between uses.
2. If “OL” appears in the display during a measurement,
the value exceeds the range you have selected. Change to a
higher range.
NOTE: On some low AC and DC voltage ranges, with the test
leads not connected to a device, the display may show a
random, changing reading. This is normal and is caused by
the high-input sensitivity. The reading will stabilize and give
a proper measurement when connected to a circuit.
MODE BUTTON
To select DC/AC Voltage, DC/AC Current, Resistance, Diode,
continuity and Capacitance check.
RANGE BUTTON
When the meter is first turned on, it automatically goes into Auto-
Ranging. This automatically selects the best range for the
17 18

measurements being made and is generally the best mode for
most measurements. For measurement situations requiring that
a range be manually selected, perform the following:
1. Press the RA GE button. The “AUTO” display
indicator will turn off.
2. Press the RA GE button to step through the available ranges
until you select the range you want.
3. Press and hold the RA GE button for 2 seconds to
exit the Manual Ranging mode and return to Auto-Ranging.
(If backlight turns on, please press BACKLIGHT button again
and it will turn off)
DATA HOLD / BACKLIGHT BUTTON
The Data Hold function allows the meter to "freeze" a
measurement for later reference.
1. Press the DATA HOLD button to “freeze” the reading on the
display. The indicator “HOLD” will be appear in the display.
2. Press the DATA HOLD button to return to normal
operation.
If you Press and hold the BACKLIGHT button for 2 seconds,
the d splay back l ght w ll turn ON.
Press BACKLIGHT button 2 seconds aga n to ex t the l ght
mode.
RELATIVE BUTTON
The relative measurement feature allows you to make
measurements relative to a stored reference value. A reference
voltage, current, etc. can be stored and measurements made in
comparison to that value. The displayed value is the difference
between the reference value and the measured value.
1. Perform any measurement as described in the operating
instructions.
2. Press the RELATIVE button to store the reading on the
display and the "REL" indicator will appear on the display.
3. The display will now indicate the difference between the
stored value and the measured value.
4. Press the RELATIVE button to return to normal
operation.
Hz/% BUTTON
Press the Hz/% Button to alternate between Hz and % Duty Cycle
while in the Hz/%duty test function. Please see the
Voltage/Current requirement and range of Frequency table below.
Range ( DC/AC ) Sensitivity Frequency width
4V ≥1.5V rms 5Hz~10kHz
17 18

40V, 400V ≥6.5V rms 5Hz~20kHz
≥12V rms 5Hz~200kHz
1000V/750V ≥420V rms 50Hz~1kHz
400mA ≥45mA rms 5Hz~5kHz
10A ≥4A rms 5Hz~1kHz
ote: The above data is only for reference.
/℃ ℉ BUTTON
The /℃ ℉ Button is used to select between ℃ and ℉ when
making temperature measurements. Set the rotary switch at the
TEMP position and “℃” will be displayed. The LCD display will
show temperature in degrees ℃. Push the / ℃ ℉ SWITCH again,
then “℉” will be displayed. At the same time the LCD display will
show temperature in degrees ℉. If pushed again , it will return to
.℃
AC OR DC VOLTAGE MEASUREMENTS
1. Insert the black test lead banana plug into the
Negative COM jack and the red test lead banana plug into
the Positive + jack.
2. Turn the rotary switch to the VDC/AC position.
3. Press the MODE button to select AC or DC Voltage
4. Touch the test probes to the circuit under test and read
the voltage on the display.
Note: Pressing the Hz/% button while in the voltage function will
switch the display to frequency or duty cycle
AC OR DC CURRENT MEASUREMENTS
CAUTION: Do not make current measurements on the
10A scale for longer than 30 seconds every 15 minutes.
Exceeding 30 seconds may cause damage to the meter
and/or the test leads.
1. Insert the black test lead banana plug into the Negative COM
jack and the red test lead banana plug into the…
a. Positive + jack for currents to 400mA OR
b. 10A jack for currents to 10A
2. Turn the rotary switch to the uA, mA or A position.
3. Press the MODE button to select AC or DC current
4. Touch the test probes in series with the circuit under test and
read the current on the display.
Note: Pressing the Hz/% button while in the current function will
switch the display to frequency or duty cycle.
Resista ce, Diode, Co ti uity, OR Capacita ce
Measureme ts
WARNING: To avoid electric shock, disconnect power to
the unit under test and discharge all capacitors before
taking any resistance or capacitance measurements.
1. Insert the black test lead banana plug into the Negative COM
17 18

jack and the red test lead banana plug into the Positive +

6. When on the continuity range, a beeping sound shall be heard
if the resistance is lower than 30Ω
7. When measuring the forward voltage across diode a normal
diode will indicate 0.4V or 0.7V and the reverse voltage will
indicate “OL” (same as on open condition ). For a short-
circuited diode, a value 0 mV will be display.
