cUrrent MeasUreMent

1.: Set rotary switch to the „1000A, 400A” or
„40A” position then select the voltage type
(AC or DC) by pushing the „SELECT” button.
Press the trigger to open the transformer
jaws and clamp onto one conductor only.
NOTE: During current measurement, keep
the transformerjaws fully closed. Otherwise,
accurate measurement cannot be made.
Warning: Do not make current measurement
with the test leads connected to the instru­ment.

voltage MeasUreMent

Set the rotary switch to the „V” range then by
the „SELECT” button select the voltage type,
DC or AC voltage.
Connect the black and red test leads to the
„COM” and „VΩHz” terminals.

Connect the test leads to the circuit being
measured.
Read the displayed value on the instrument’s
screen.

resistance MeasUreMent

Set the rotary switch to the „Ω” range.
Connect the black and red test leads to the
„COM” and „VΩHz” terminals.
Connect the test leads to the circuit being
measured.
Read the displayed value on the instrument’s
screen.
WARNING: Always make sure that the circuit
under test is powered o.

capacitance MeasUreMent

Set the rotary switch to „- | | -” range.
Connect the black test leads to the „COM”

User Manual

and the red test leads to „VΩHz” terminals.
Connect the test leads to the capacitor being
measured and read the displayed value on
the screen

NOTE: The meter only do automatically capa­citance measurement.

WARNING: To avoid electrical shock and/or
damage to the instrument, disconnect circuit
power and discharge all high-voltage capaci­tors before measuring capacitance.

freqUency MeasUreMent

Set the rotary switch to „Hz” range.
Press the „Hz/DUTY” key to select the mea­surement function (frequency or duty cycle
measurement).
Connect the black test leads to the „COM”
and the red test leads to „VΩHz” terminals.
Connect the test leads to the circuit under
test and read the displayed value on the scre­en.
NOTE: The meter only do automatic frequ­ency measurement.

diode test

Set the rotary switch to “ ” range.
Press the „SELECT” key once to activate Diode
Test.
Connect the black test leads to the „COM”
and the red test leads to „VΩHz” terminals.
Connect the test leads to the diode terminals
of the circuit under test and read the displa­yed value on the screen.

continUity cHeck

Set the function switch to “ ” range. Push
the „SELECT” button to select the continuity
check mode.
Connect the black test leads to the „COM” and
the red test leads to „VΩHz” terminals.
Connect the test leads to the circuit under test
and read the displayed value on the screen.

If the resistance is less than approximately
50Ω, an audible signal will sound.

WARNING: Always make sure that the circuit
under test is powered o.
NOTE: To avoid electrical shock and damage
to the instrument or faulty measurement,
disconnect circuit power and discharge all
high-voltage capacitors before measuring
continuity

relative MeasUreMent Mode

The Relative mode permits the user to store a
reference reading and compare all subsequ­ent readings to the stored reference value by
pressing the „REL” button the instrument will
store the valued measure as 0. Subsequent
readings will display a value that is the die­rence between the actual reading and the
stored reference value.

1. Press the „REL” key when the desired va­lued is displayed on the meter. This becomes
the stored reference. The „REL” symbol will
appear on the LCD.

2. Take measurements and note that the me­ter displays the actual reading minus the re­ference reading.

3. Press the „REL” key to return to normal ope­ration. The „REL” symbol will switch o.

data Hold

To freeze the LCD meter reading, press the
„HOLD” button once during measurement
process. While data hold is active, the „HOLD”
signal appears on the LCD, an audible sound
can be heard and the instrument will store
the measured value. Press the „HOLD” button
again to return to normal operation.

sleep fUnction

This function causes the instrument to au­tomatically enter the sleep (powered down)
mode about 20 minutes after the last switch

or button operation. To exit the sleep mode,
turn the function selector switch back to any
position, or press any button. Befor activating
the istrument, make sure that the test leads
are not connected to any circuit in order to
avoid any damage or electrical shock.

Battery replaceMent

Replace the battery as soon as the battery in­dicator appears on the screen to avoid false
readings.

To replace the 9V (IEC 6F22) battery:

Turn the Meter o and remove all the con­nections from the input terminals.
Set the function selector to “OFF” position.
Turn the Meter’s front case down.
Remove the screw from the battery compart­ment, and separate the battery compartment
from the case bottom.
Take out the old battery and replace with a
new 9V battery (IEC 6F22).
Rejoin the case bottom and the battery com­partment, and reinstall the screw.

Maintenance

• Periodically wipe the case with a damp

cloth and mild detergent.

• Do not use abrasives or solvents.

• Dirt or moisture in the terminals can aect

readings.

To clean the terminals:

- Turn the meter o and remove all test
leads.

- Shake out any dirt that may be in the
terminals.

- Soak a new swab with a cleaning and oiling
agent.

- Work the swab around in each terminal.
The oiling agent insulates the terminals from
moisture-related contamination

Warnings

• The rotary switch should be placed in the

correct position to prevent the Clamp Meter
during measurement process.

• Pay attention when you apply more than

50V. If the value to be measured is unknown,
use the maximum measurement position
and reduce the range step by step until a sa­tisfactory reading is obtained.

• Use the proper terminals, functions, and

range for your measurements.

• When servicing the Clamp Meter, use only

the same model number or identical electri­cal specications replacement parts.

• Do not apply more than the rated voltage,

as marked on the Meter, between the termi­nals or between any terminal and ground. If
the value to be measured is unknown, use
the maximum measurement position and re­duce the range step by step until satisfactory
reading is obtained.
