OPERATING GUIDANCE

Reading Hold
In the process of measurement, if reading hold is required, press “HOLD/B.L” key, the value on the display will be locked. Press “HOLD/B.L” key again to cancel reading hold state.

Manual Measuring Range
RAN key is automatic/manual measuring range key to trigger mode. The preset one is automatic measuring range. Press to switch to manual measuring range. In the manual measuring range mode, click once to change to upper range. Continue to the top range, then continue to press this key to change to the bottom range. If this key is pressed more than 2 sec, it will switch back to automatic measuring range state.

Max/Min Measurement Choice

Press “MAX/MIN” key to enter MAX mode, and always keep measurement maximum value; press “MAX/MIN” key again, the meter will enter minimum value measurement state; press “MAX/MIN” key for the third time, the meter will display the difference of máximum and minimum value; press “MAX/MIN” key to repeat the above operations by recycling.
After entering MAX or MIN mode, it will automatically save the measured maximum or minimum value.
If the user presses “MAX/MIN” key more than 2 sec, the meter will restore normal measuring range.
Note : For using the maximum/minimum value measurement mode, the manual range mode must be active.

Function Switch
In the voltage mode, press “FUNC” button for changing to DC or AC current type.

REL Measurement

REL button is relative value Measurement button. The current display value can be stored in the memory as reference value. When the user measures later, the display value is the difference for input value minus reference value. ie. RELΔ(current reading)= Input value – Reference value.

Back Light And Clamp Head Light

In the process of measurement, if ambient light is too dark to read, press “B.L/HOLD” key for two seconds to turn on the display backlight and the clamp head light. Both lights will automatically turn off after about 30 seconds.
During this period, pressing “B.L/ HOLD” key for two seconds will turn off the display backlight and the clamp head light.
Note: When battery voltage ≤ 3.6V, the LCD displays “ “ (undervoltage) symbol.When the user uses the backlight, the battery voltage drops below 3.6V, due to high working current. The “ “ symbol may appear, and Measurement accuracy is not guaranteed. Continue to use the meter normally without using backlight. Do not replace the battery until “ “ symbol shows under normal conditions.

Automatic Power-Off

If there is no operation during any 30 minutes after turning the machine on, the meter will enter suspended stated, automatically powering off to save the battery.
After automatic power-off, press any key, the meter will turn on again.
If the user holds “FUNC” key when powering on, it will cancel automatic power-off function.

Measurement preparation

Turn the transfer switch to turn on the power. When battery voltage is low (about ≤ 3.6V, LCD displays “ “ symbol, replace the battery.
symbol means that input voltage or current should not be more than the specified value, which is to protect the internal line from damage.
Place transfer switch to required measuring function and range.
When connecting line, first connect the common test line, then connect charged test line. When removing line, remove charged test line first.

Current measurement
WARNING
Electric shock Hazard.
Remove the probe from the meter before mesuring with current clamp

Measuring switch is placed to position A. At this time, the meter is in AC current measurement state. Choose appropriate measuring range.
Hold the trigger, open clamp head, clip one lead of measurement circuit to be tested in the clamp.
Read the current value on the LCD display.

Note:

Clamping two or more lines of circuit to be tested simultaneously will not get the correct easuring results
To get accurate Reading, connect the wire to be tested at the center of current clamp
“ ” symbol indicates that máximum input AC current is 1000A.

Voltage measurement
WARNING: Electric shock hazard.
Pay special attention to avoid shock when measuring high voltage. Don’t input voltage more than 750Vac T-RMS.

Insert black probe to COM jack, insert red probe to INPUT jack, choose appropiated measuring range.
Place transfer switch to AC voltage or position. At this time, the meter is in the DC voltage measurement state. To measure AC voltage, press FUNC button to enter AC voltage measurement state
Connect the probe with voltage source or both ends of load in parallel for measurement.
Read the voltage on the LCD.

Note:

In the small voltage measuring range, if the probe is not connected with the circuit to be tested, the meter may have fluctuating readings, which is normal and caused by the meter´s high sensitivity. When the meter is connected with the circuit under test, you will get actual measured value
On the relative measurement mode, automatic measuring range is invalid. Manual measuring range must be selected.
“ ” symbol indicates that máximum input voltage is 1000VDC / 750VAC. Maximum input voltage at mV is 600mVac/dc
If the readings measured by the meter is more than 600VAC(RMS), it will be send out “beep” alarm.

Resistance Test
WARNING: Electric shock hazard.

When measuring circuit impedance, determine that the power supply is disconnected and the capacitor in the circuit is completely discharged.

Insert black probe to COM jack, insert red probe to INPUT jack.
Place measuring range switch to position “Ω”. At this time, the meter is in the measurement state.
Connect the probe to the both ends of resistor or circuit to be tested for measurement.
LCD will show readings.

Note:

When the input end is open, LCD shows “OL” outrange state. .
When the resistance to be tested > 1M, the meter reading will stabilize after a few seconds, which is normal for high resistance readings

Diode Test

Insert black probe to COM Jack, insert red probe to INPUT Jack
Measuring switch is placed to position
Connect the red probe to diode anode and connect the black probe to diode cathode to make test.
Read on the LCD

Note:

What the meter shows is approximation of diode forward voltage drop.
If the probe has reverse connection or the probe is open, the LCD will show “OL”.

Circuit Continuty Test

WARNING: Electric shock hazard.

When measuring circuit continuity, determine that the power supply is disconnected and the capacitor in the circuit is completely discharges.

Insert black probe to COM Jack, insert the red probe to INPUT Jack
Measuring switch is placed to position
Connect the probe to the both ends of circuit to be tested for the Measurement
If the resistance of circuit under test is less than 50Ω, the meter´s built-in buzzer may sound.
Read the circuit resistance value on the LCD.

NCV Measurement

Turn the meter to NCV mode
Place the meter top close to the conductor. When test voltage is greater than 110Vac (T-RMS), the meter´s LED indicator will blink and the buzzer will give an alternating high-low alarm sound.

Note:

Even there is no indication, voltage may exist still. Don’t use non-contact voltage detector to judge whether there is voltage in the wire. Detection operation could be affected by socket design, insulation thickness, type and other factors.
When inputting voltage on the meter input terminal, due to the existence of the induced voltage, voltage induction indicator also may light.
External sources of interference (such as flashlight, motor, etc.) may incorrectly trigger noncontact voltage detection.

MAINTENANCE

Replace Battery

WARNING
To avoid electric shock, make sure that the test leads have been clearly move away from the circuit under measurement before opening the battery cover.

If the symbol “ “ appears, it means that the batteriers should be replaced.
Loosen the screw of the battery cover and remove it.
Replace the used battery with a new one.
Return the battery cover and tighten the screw.
Note: The battery polarity can´t be reversed

Replace probe
Replace test lead if leads become damaged or worn.

WARNING: Use meet EN 61010-031 standard, rated CAT IV600V, or better test leads
WARNING: To avoid electric shock, make sure the probes are disconnected from the measured circuit before removing the rear cover. Make sure the rear cover is tightly screwed before using the instrument.
