W

Warning: Read Before Using

To avoid possible electric shock or personal injury:

• Use the Meter only as specified in this manual or the protection

provided by the Meter might be impaired.

• Avoid working alone so assistance can be rendered.

• Never measure AC current while the test leads are inserted into the

input jacks.

• Do not use the Meter in wet or dirty environments.

• Do not use the Meter if it appears damaged. Inspect the Meter before

use. Look for cracks or missing plastic. Pay particular attention to the

insulation around the connectors.

• 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 the Meter.

• Have the Meter serviced only by qualified service personnel.

• Use extreme caution when working around bare conductors or bus

bars. Contact with the conductor could result in electric shock.

• Do not hold the Meter anywhere beyond the tactile barrier.

• When measuring current, center the conductor in the clamp.

• 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 or

battery cover.

• Never operate the Meter with the battery cover removed or the case

open.

• Never remove the battery cover or open the case of the Meter without

first removing the test leads or the jaws from a live conductor.

• Use caution when working with voltages above 30 V ac rms, 42 V ac

peak, or 60 V dc. These voltages pose a shock hazard.

• Do not attempt to measure any voltage that might exceed the

maximum range of the Meter.

• Use the proper terminals, function, and range for your measurements.

• 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.

• Use only 1.5V AA batteries, properly installed in the Meter case, to

power the Meter.

• To avoid false readings that can lead to electrical shock and injury,

replace the battery as soon as the low battery indicator (N) appears.

Check Meter operation on a known source before and after use.

• When servicing, use only specified replacement parts.

• Adhere to local and national safety codes. Individual protective

equipment must be used to prevent shock and arc blast injury where

hazardous live conductors are exposed.

• Do not use the Meter if the wear indicator in the jaw opening is not

visible.

• Only use the test lead provided with the Meter or UL Listed Probe

Assembly rated CAT III 1000 V or better.

Warning

To avoid possible electric shock or personal injury:

• When measuring current, center the conductor in the clamp.

• When making current measurements, disconnect the test leads from

the Meter.

• Keep fingers behind Tactile Barrier.

• Use the proper function and range for measurements.

• Disconnect circuit power and discharge all high-voltage capacitors

before testing resistance and diode.

• When using probes, keep fingers behind the finger guards.

• Connecting test leads:

- Connect the common (COM) test lead to the circuit before connecting

the live lead;

- After measurement, remove live lead before removing the common

(COM) test lead from the circuit.

Button Description

SELECT Press SELECT button to select the alternative

measurement function on the rotary switch.

Press button to turn ON or to turn OFF LCD

backlight and flashlight. LCD backlight and flashlight

automatically turns off after approximately 32 seconds

HOLD /

ZERO

Press HOLD to freeze the display reading ( is

displayed) and releases the reading when pressed a

second time.

W Warning

To avoid possible electric shock or personal injury,

when Display HOLD is activated, be aware that the

display will not change when you apply a different

voltage.

Press ZERO (HOLD) > one second to clear last

reading from the display ( is displayed) and establish

a baseline for applicable selected functions.

DC-Zero mode for DC and AC+DC currents. Press

ZERO (HOLD) > one second to activate DC-Zero (display

shows “dc_0” for one second). When nulled value is

larger than +/- 5 DC A, an acoustic warning (3 short

beeps) will occur.

REC /

PEAK-RMS

Press REC button to activate maximum, minimum and

average reading memory mode ( MAX MIN AVG

is displayed). The meter beeps when MAX and MIN

reading is updated during measurement. Press REC

button again to read the MAX, MIN and AVG reading

in sequence. Press REC button > one second to exit

MAX/MIN/AVG reading memory mode.

Press REC / PEAK-RMS button > one second to enter

PEAK-RMS mode ( is displayed) to capture

inrush current or voltage RMS values (80 ms). Press a

second time > one second to exit.

Note: Auto Power Off is automatically disabled under

MAX/MIN/AVG and PEAK-RMS modes.

Hz / CREST Press Hz button to activate frequency measurement

mode. Press a second time to exit.

Press REC button > one second to activate CREST mode

(5 ms) to capture current or voltage peak values (

MAX is displayed). Press again to toggle between

MAX and MIN. The meter beeps when MAX or

MIN reading is updated during measurement. Press

CREST button > one second to exit CREST mode.

Note: Auto Power Off is automatically disabled under

CREST modes.

Measuring AC and DC Voltage

To measure ac or dc voltage:

1. Turn the rotary function switch to or

2. Press SELECT button to choose measurement function (AC V, DC V,

DC+AC V, Hz or EF - Non contact voltage detection). The display reflects

the chosen function mode.

3. Connect the black test lead to the COM terminal and the red test lead

to the V terminal. Before connecting the probes to the measurement

points, add any clips to the probes that are necessary.

4. Measure the voltage by touching the probes to the desired test points

of the circuit.

5. View the reading on the display.

6. When measuring AC voltage, press Hz button to view the frequency

reading on the display.

Note:

• AC V (and hence DC+AC V and Hz) function is equipped with digital

low-pass filter, and is capable of dealing with VFD (Variable Frequency

Drives) signals. It also improves AC V reading stability in noisy electrical

environments.

Voltage Detection (NCV)

Non-Contact Voltage Detection:

1. Turn the rotary switch to NCV (EF). Press SELECT button to toggle

NCV (EF) mode (“EF” is displayed).

2. The voltage detection antenna is located along the top-right

end of the stationary clamp jaw for detecting electric field surrounds

energized conductors

3. Detected electric field signal strength is indicated by a series of bar-

graph segments on the display and beeper. The stronger the electric

field detected, the more bar-graph segments are displayed and more

intense beep sounds.
