B00A AC/DC Clamp Meter with inrush current capture.
Safety information
AWarn'ngs: Read First
To avoid possible electric shock or personal injury, please obey the following instructions:
« Please read this manual carefully before using the instrument, and pay attention to safety
warning information.
« Avoid using the instrument alone.
* Never measure AC current while the test leads are still insert into the input jacks.
* Do not use the meter in wet or dirty environments.
* Inspect the test leads before use. Do not use them if insulation is damaged or metal is exposed.
« Check the test leads for continuity. Replace damaged test leads before using.
* Use extreme caution when working around bare conductors or bus bars. Contact with the
conductor could result in electric shock.
« Do not apply more than the rated voltage, as marked on the meter, between the terminals or
between any terminal and earth ground.
* Remove test leads from the Meter before opening the Meter case.
1

Never operate the Meter with the back cover removed or the case open.
Never remove the back cover or open the case of an instrument without first removing the test
leads or the jaws from a live conductor.
Use caution when working with voltages above 30V ac RMS, 42V ac peak, or 60V dc. These
voltages pose a shock hazard.
Do not attempt to measure any voltage that might exceed the maximum range of the Meter-
600V RMS.
Do not operate the Meter around explosive gas, vapor, or dust.
When using probes, keep fingers behind the finger guards.
When making electrical connections, connect the common test lead before connecting the live
test lead; when disconnecting, disconnect the live test lead before disconnecting the common
test lead.
Disconnect circuit power and discharge all high-voltage capacitors before testing resistance,
continuity, or diodes.
Check the operation of the meter at a known source before and after use.

Advanced Functions
AC current measurement with “Inrush” function
Gurent
Inrush current is the instantaneous high input
current drawn by a power supply or electrical
equipment at turn-on. This arises due to the [iush curent magnitude ]
Sieady-saio curentvalus
high initial currents required to charge the capacitors
and inductors or transformers.
Time
Puise width
Note: The measuring time of inrush current is about 100ms.
When an electrical device powers is on, inrush current is the surge or momentary burst of current
that flows into it.

Operating Instructions

Calibration
1. The meter automatically performs a self-test when switched on and displays "CAL" in the screen,
do not press the Jaw release to open the clamp at this time.
2. The buzzer beeps "beep, beep, beep” indicate the completion of the self-test.

Auto-ranging
button to turn on the power supply of the meter. After the self-test is completed, the
meter will display “Auto” and enter the smart measurement mode.
2. Don't need to select the measurement function, the instrument will automatically identify and
measure the AC/DC voltage, AC/DC current, resistance, continuity. Current is measured by the
clamp, and the other measurements will need to use the pen input.
3. Read the measurement results from the display screen. The frequency is displayed when the AC
signal is measured
Note1:Minimum identifiable DC current 0.8A
Minimum identifiable AC current 0.5A.
Minimum identifiable AC/DC voltage 0.8V.
Note2: Automatic identification priority: resistance, DC voltage, AC voltage, DC current, AC current.
Connecting test leads
Do not test if leads are improperly seated.
Results could cause intermittent display readings.
To ensure proper connection, firmly press leads
into the input jack completely.

measurement function.
3. In the DC current measurement, if the display number is not zero when the instrument is not
measuring, please press and hold the (&) button, then the meter will display "ZERO" and then you
can measure.
4. Press the jaw release to open the clamp, clamp the conductor and release it until the clamp are
completely closed. If the conductor is not in the center of the pliers, errors will occur.
5. Read the measurement results from the display screen. The frequency is also shown on the
display when measuring AC current
Note
» Use the current clamp to surround one conductor.
» If the supply and return conductors (.. L and N) are measured, the current will cancel each
other out and no measurement will be displayed. The cables of household appliances usually
contain L and N conductors. A cable separator is required to measure with the current probe.
» If several supply conductors (e.g. L1 and L2) are measured, the currents add up.
