and then the “TEST” button, if there is any static electricity present
in the item being tested and its voltage is over 30V, it will fail and no
high-voltage testing will occur, “>30V” will display on the LCD, the
symbol “ ” flashes, and the buzzer will sound. Otherwise it will
enter into the formal testing process and the high-voltage will show
on the primary display, the insulation resistance in MΩ is indicated
in-phase with the analog bar; on the top right corner display, the
tested insulation voltage in V (DC) is indicated, the symbol “ ”
flashes and the buzzer will sound.

the “LOCK “ status will exit from the “LOCK” status and shut-off the
testing voltage, simultaneously the resistance value indicated in the
primary display will be held, and the top right corner display will still
show the status of the insulation voltage for the item tested.
Turning the function switch to off or pressing the EXIT button
will exit from the testing procedure during the process.
POWER TOOLS AND SMALL APPLIANCES
This test would also apply to other similar equipment that has a line
cord. For double insulated power tools, the megohmmeter lead shown
connected to the housing would be connected to some metal part lf
the tool(e.g. chuck, blade).
Note: The switch of the device must be in the “ON” position and the
main power should be disconnected.
MOTORS
AC-Disconnect the motor from the line by disconnecting the wires at
the motor terminals or by opening the main switch. If the main switch
is used and the motor also has a starter then the starter must be held,
by some means, in the “ON” position. In the latter case, the measured
resistance will include the resistance of the motor, wire and all other
components between the motor and the main switch. If a weakness is
indicated, the motor and other components should be checked
individually. If the motor is disconnected at the motor terminals,
connect one megohmmeter lead to the grounded motor housing and
the other lead to one of the motor leads. DC - Disconnect the motor
from the line. To test the brush rigging, field coils and armature
connect one megohmmeter lead to the grounded motor housing and
the other lead to the brush on the commutator. If the resistance
measurement indicates a weakness, raise the brushes off the
commutator and separately test the armature, field coils and brush
rigging by connecting one megohmmeter lead to each of them
individually, leaving the other connected to the grounded motor
housing. The above also applies to DC Generators.
CABLES
Disconnect the cable from the line. Also disconnect opposite end to
avoid errors due to leakage from other equipment. Check each
conductor to ground and /or lead sheath by connecting one
megohmmeter lead to a ground and /or lead sheather and the other
megohmmeter lead to each of the conductors in turn. Check insulation
resistance between conductors by connecting megohmmeter leads to
conductors in pairs.
AUTORANGING/MANUAL RANGE SELECTION
When the meter is first turned on, it automatically goes into
AutoRanging. This automatically selects the best range for the
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 RANGE key. The “AUTO” display indicator will turn off.
2. Press the RANGE key to step through the available ranges until

The right auxiliary display meter will display and hold the
minimum reading and will update only when a new “min” occurs.
2.To exit MAX/MIN mode press EXIT
RELATIVE MODE
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. Note:

current. The meter can capture negative or positive peaks as fast
as 1 millisecond in duration. Momentarily press the PEAK button,
“PEAK” and “MAX” will display in left auxiliary display. MIN” will
display in right auxiliary display. The meter will update the display
each time a lower negative peak occurs. Press the EXIT button to
exit the PEAK HOLD mode. Auto Power Off feature will be
disabled automatically in this mode.

can damage the electronic parts or the case.
4. KEEP THE METER CLEAN. Wipe the case occasionally with a
damp cloth. DO NOT use chemicals, cleaning solvents, or
detergents.
5. USE ONLY NEW BATTERIES OF THE RECOMMENDED SIZE
AND TYPE. Remove old batteries so they do not leak and
damage the unit.
6. IF THE METER IS TO BE STORED FOR A LONG PERIOD OF
TIME, the batteries should be removed to prevent damage to the
unit.
BATTERY INSTALLATION
WARNING: To avoid electric shock, disconnect the test leads from
any source of voltage before removing the battery cover.
1. Turn power off and disconnect the test leads from the meter.
2. Open the rear battery cover by removing 4 screws using a cross
head screwdriver.
3. Insert the batteries into battery holder, observing the correct
polarity.
4. Put the battery cover back in place. Secure with the screws.
WARNING: To avoid electric shock, do not operate the meter until
the battery cover is in place and fastened securely.
NOTE: If your meter does not work properly, check the fuses and
batteries to make sure that they are still good and that they are
properly inserted.
REPLACING THE FUSES
WARNING: To avoid electric shock, disconnect the test leads from
any source of voltage before removing the meter cover.
1. Disconnect the test leads from the meter.
2. Remove the protective rubber holster.
3. Remove the battery cover (4 screws) and the batteries.
4. Remove the six screws securing the rear cover.
5. Gently remove the old fuse and install the new fuse into the
holder.
6. Always use a fuse of the proper size and value (0.5A/1000V fast
blow for the 400mA range, 10A/1000V fast blow for the 20A range.
7. Replace and secure the rear cover, battery and battery cover.
WARNING: To avoid electric shock, do not operate your meter until
the fuse cover is in place and fastened securely.

AC Response True rms
AC True RMS: The term stands for “Root-Mean-Square,”
which represents the method of calculation
of the voltage or current value. Average
responding multimeters are calibrated to
read correctly only on sine waves and they
will read inaccurately on non-sine wave or
distorted signals. True rms meters read
accurately on either type of signal.
