SAFETY
Please read the safety instructions provided in
the separate booklet provided with the device.
Risk of electrocution. High voltage circuits, both
AC and DC, are very dangerous and should be
measured with great care.
Turn function switch OFF when meter is not in
use. “OL“ appears when a measurement exceeds
the selected range.
BATTERY
To avoid electric shock, remove test leads from
the meter before removing battery/fuse cover.
This appliance should only be used with the
supplied 4x AAA alkaline batteries or similar AAA
batteries.
FIRST TIME USAGE
Remove all protection foils.
Open the battery compartment and insert the
4x AAA alkaline batteries. Please take care to
respect indicated polarities.
USE
RANGE-BUTTON
The autorange mode automatically selects the
proper range for the measurement being made
and is generally best for most applications.
For measurement situatons requiring that a range
be manually selected, perform the following:
· Press the RANGE-button [03]. The “AUTO”
indicator [U] will no longer be shown on the
display.
· Press the RANGE-button [03] to step through
the available ranges until the desired range is
selected.
· To exit the Manual Ranging mode, press and
hold the RANGE-button [03] until the “AUTO”
indicator [U] reappears.
NOTE
The RANGE-button [03] does not work on
Frequency Duty Cycle, Capacitance or Temper-
ature.

5
MODE-BUTTON
Press the MODE-Button [04] to select AC or DC,
Frequency or Duty Cycle, Resistance, Continuity
or Diode test and °C or °F.
REL-BUTTON
The RELATIVE function zeros out the reading on
the display and stores it as a reference.
Subsequent readings will be displayed as the
relative difference between the actual
measurement and the stored reference value.
· To activate, press the REL-button [02]. The “REL”
indicator [W] will appear on the display along
with the relative reading.
· Press the REL button [02] again to return to
normal operation.
NOTE
The meter does not AUTO-range when the
relative mode is active. The display will show
“OL”(Overload) [Z]ifthedifrenceexceedsthe
range. REL does not work on frequency, Duty
Cycle, Temperature or Low Z.
MAX/MIN/AVG-BUTTON
Press the MAX/MIN/AVG-button [12] to activate
the MAX/MIN mode. The “MAX” [Y] indicator will
appear on the LCD display. The meter will display
and hold the maximum reading and will update
when a higher “MAX” occurs.
· Press the MAX/MIN/AVG-button [12] again to
view the lowest reading. The “MIN” [Y] will ap-
pear on the LCD display. The meter will display
and hold the minimum reading and will update
when a lower “MIN” occurs.
· Press the MAX/MIN/AVG-button [12] again to
view the average reading. The “AVG“ [Y] symbol
will appear on the LCD display. The meter will
display the running average and will update

6
when the average value changes.
· Press and hold the MAX/MIN/AVG-button [12]
to end MAX/MIN/AVG and return to normal
operations.
NOTE
MAX/MIN does not work on Frequency, Duty
Cycle, Capacitance or Temperature.
BACKLIGHT/HOLD-BUTTON
To freeze the reading on the LCD display, press
the HOLD-button [10]. The “HOLD” indicator [V]
will be displayed while the reading is being held.
Press the HOLD-button [10] again to exit HOLD
and return to normal operation.
· To turn the backlight in the display on, press
and hold the HOLD button until the backlight
turns on. To turn the backlight off, press and
hold the HOLD buttton until the backlight turns
off.
AUTO BACKLIGHT
When the meter is in the darkness, the backlight
can be automatically opened, not controlled by
the button.
FLASHLIGHT/PEAK-BUTTON
Press the PEAK-button [11]toturntheashlight
on or off. The PEAK function is accessible when
measuring AC voltage or Current. It captures and
displays the highest positive peak and the high-
est negative peak of the AC waveform.
· Press and hold the PEAK-button [11] untill “Peak
MAX” [X] appears on the display. The meter
will display the highest reading and will update
the reading when a higher positive peak occurs.
· To view highest negative peak, press and hold
the PEAK-button [11] until “Peak MIN” [X]
apears on the display. The meter will display
and hold the largest negative reading. The
meter will update the reading when a larger
negative peak occurs.
· Press the PEAK-button [11] for approximately
one second to switch between Peak MAX and
Peak MIN readings.

7
· Press and hold the PEAK-button [11] to exit
PEAK and return to normal operation.
NOTE
The meter does not Autorange when the Peak
mode is active. The display will read “OL” (over-
load) [Z] if the range is exceeded. When this
occurs, exit Peak and use the RANGE-button [3]
to select a higher range. Peak does not work on
DCV, DCA, Frequency, Duty Cycle, Capacitan-
ceor Low Z.

NOTE
Observe all safety precautions when working
on live voltages!
· Set the rotary function switch [05] to the V
~Hz% position.
· Press the MODE-button [04] to select AC or DC
voltage. The AC “~” [S] or DC “ ” [Q] symbol
will appear on the display.
· Insert the black test lead into the COM input
jack [08] and the red test lead into the V input
jack [09].
· Touch the test lead probes to the circuit under
test. If measuring DC voltage, touch the red
test lead to the positive side of the circuit and
the black test lead to the negative side of the
circuit.
· Read the voltage on the display.

· To select Frequency, press and hold the
MODE-button [04] until the “Hz” symbol [K]
appears on the display. To select % Duty Cycle,

when the meter is set to AC voltage.
LOW Z VOLTAGE
— +

9
NOTE
Observe all safety precautions when working
on live voltages!
Do not connect to circuits that exceed 600V
AC/DC when the meter is set to Low Z!
Low Z is used when there is a suspicion of a
“ghost” voltage. Ghost voltages are present when
non-powered wires are in close proximity to wires
powered by AC voltages. Capacitive coupling
between wires make it appear that non-powered
wires are connected to a real source of voltage.
The low Z setting places a load on the circuit,
which dissipates and greatly reduces ghost
voltage.
· Set the rotary function switch [05] to the Low Z
position.
· Press the MODE-button [04] to select AC or DC
voltage. The AC “~” [S] or DC “ ” [Q] symbol
will appear on the display.
· Insert the black test lead into the COM input
jack [08] and the red test lead into the V input
jack [09]. If measuring DC voltage, touch the
red test lead to the positive side of the circuit
and the black test lead to the negative side of
the circuit.
· Read the voltage on the display.

1000V. Measurements in the 10A range should
be limited to 30 seconds maximum every 15
minutes.
· Insert the black test lead into the negative COM
input jack [08]
· For current measurements up to 600mA, set the
rotary function switch [05] to the mA position

the rotary function switch [05] to the µA posi-
tion and insert the red test lead into the µA/mA
input jack [07].
· For current measurements up to 10A, set the
rotary fucntion switch [05] to the 10A position
and insert the red test lead into the 10A input
jack [06].
· Press the MODE-button [04] to select AC or DC
current. The AC “~” [S] or DC “ ” [Q] symbol will
appear on the display.
· Remove power from the circuit under test, then
open up the circuit at the point where you wish
to measure current.
· Touch the test lead probes in series with the
circuit being measured. For DC current, touch
the red probe to the positive side of the circuit
and touch the black probe to the negative side
of the circuit.
