in this manual; otherwise, the protecon provided by the meter may be impaired.
WARNING
Idenes hazardous condions and acons that could cause BODILY HARM or DEATH.
CAUTION
Idenes condions and acons that could DAMAGE the meter or equipment under test
WARNING
• When using test leads, keep your ngers behind the nger guards.
• Always use proper test probes for measurements.
• Discharge all high-voltage capacitors before tesng.
• Do not use meter around explosive gas or vapor.
• To reduce the risk of re or electric shock do not expose this product to rain or moisture.
• Do not touch any circuits or parts of circuits if there may be 30VAC rms or 30 VDC on
them.
• Be careful of the test probes, which are sharp and dangerous.
• Never connect a source of voltage to the meter. That may be damage the meter.
• Discharge all capacitors before tesng.
• Do not expose meter to extremes in temperature or high humidity.
• Do not drop the meter. That maybe damage the meter or cause out of specicaon.
• Never use unspecied adaptor to charge meter.
• Do not connue to charge more than 8 hours to prevent the baery damage.

Parallel Measuring
Phase Drawing
The phasor is a constant complex number, usually expressed in exponenal form,
represenng the complex amplitude (magnitude and phase) of a sinusoidal funcon of me.
When θ (phase) > 0°
Then Z (impedance) is
Capacive reactance
When θ (phase) < 0°
Then Z (impedance) is
Inducve reactance
When θ (phase) = 0°
Then Z (impedance)
is Resistance

Making Basic Measurements
Discharge the DUT (Device Under Test) before connecng the test probes.
The gures on the following pages show how to make basic measurements.
Power On/O
Press the central power buon to turn on. Press and hold the power
buon > 2 sec to turn o.
Auto Power O
If there is no any acon in the meter, then the meter will
automacally turn o to save the power of baery. The default
APO me is 10 minutes.
Backlight
When the meter is turned on, the backlight will be turned on
automacally. Press the central power buon to turn on/o the
backlight.
Preparaon and Cauon Before Measurement
Observe the rules of Warnings and Cauons

Measuring L/C/R
Measuring D/Q/θ/DCR
Discharge the DUT (Device Under Test) before connecng the test probes.
The gures on the following pages show how to make basic measurements.
The auto test mode is the default mode when the meter is turned on. When the
meter in auto test mode, it will automacally detect the DUT and show the suitable
result on the dis play.
The meter can measure D (dissipaon factor), Q (quality factor), θ (phase) and
DCR (DC resistance) on the DUT.
• Press the D/Q/θ/DCR buon to enter D/Q/θ/DCR test mode.
• In D/Q/θ/DCR test mode, press the D/Q/θ/DCR buon to select measuring funcon.
• In auto test mode, press the AUTO L/C/R buon to enter manual test mode.
• In manual test mode, press the AUTO L/C/R buon to select measuring funcon.
• To return the auto test mode, press and hold the AUTO L/C/R buon > 2 sec.

10
Select Test Frequency
Open/Short Calibration
The default test frequency is 1kHz when the meter is turned on.
Press the Cal/Hz buon to select the test frequency.
In order to achieve the best measuring result, the calibraon has to be done
before measuring the DUT. To calibrate the meter, press and hold the Cal/Hz buon > 2 sec.
When “OPEn” appears on the display, make the test probes open, and press the Cal/
Hz buon to start open calibraon. During open calibraon, the “OPEn” blinks on
the display. About 15 seconds later, the result of the open calibraon appears on the
display. If the result shows "PASS", press the Cal/Hz buon to next step. If the result
shows "FAIL", press the Cal/Hz buon to exit calibraon mode.

11
When “Srt” appears on the display, make the test probes short closely, and press
the Cal/Hz buon to start short calibraon. During short calibraon, the “Srt” blinks on t
he display. About 15 seconds later, the result of the short calibraon appears on the
display. If the result shows "PASS", press the Cal/Hz buon to nish calibraon. If the result
shows "FAIL", press the Cal/Hz buon to exit calibraon mode.

12
Relative Δ
Hold
Press and hold the Δ/H buon > 2 sec to start the relave mode. The meter stores the last
reading as reference and shows the indicaon “Δ” on the display. In this mode, the meter
deducts the reference from each reading, and shows the result on the display. If the result is
negave, the “Er” appears on the display. Press the Δ/H buon > 2 sec to exit this mode.
Press the Δ/H buon to enter the hold mode. The meter holds the last reading and shows the
indicaon “H” on the display. Press the Δ/H buon again to exit the hold mode.

13
Charge
Connect to PC
There is a Li-ion baery as power source in the meter. When the baery indicator shows low
baery, charge the meter as soon as possible. When baery charge complete, the baery
indicator will show full level on the display.
• Always use the typical mini USB plug adaptor to charge.
• Do not connue to charge more than 8 hours to prevent the baery damage.
The meter can connect to PC by USB cable. Follow the below steps to setup.
1. Connect PC and meter by USB cable.
2. Turn on the meter power.
3. Insert the soware CD to CD-ROM of PC.
4. Install the driver and soware.
5. Start the soware and communicate with meter.
