Safety Instructions
The design and manufacture of instruments strictly comply with the requirements of IEC61010-1 CAT.I 600V over-voltage safety
standards and pollution level 2.
Warning
/N In order to avoid possible electric shock or personal injury and other safety accidents, please abide by the following
Specifications:
@ Read this manual before using the instrument, and pay special attention to safety warning information.
@ Check whether the instrument case is damaged.
® Comply with local and national safety code.
Safety Operating Procedures
® Remove probe before opening the outer cabinet or battery cover.
@ Put your fingers behind the finger protector of the probe.
® Connect the neutral line or the ground line first, then connect the live wire.
@ Disconnect the live wire first, then disconnect the neutral line and ground
1

@ Replace the battery when it shows low battery indicator.
Cautions
@ Don't use the instrument around explosive gas, steam or in wet environment.
® The instrument is used with specified category, voltage or current rating
® Be careful if the measurement exceeds 60V DC. 30V AC true RMS or 42V peak.
ing the known voltage to check whether the meter work is normal, if it is not normal or damaged, do not use.

Backlight: Long press the button to tun on/off the backlight.
Data hold: Short press the button to tum on/off the data hold function.
Flashlight: Long press to tum on/off the flashlight.
Sleep Mode
‘The Meter automatically enters sleep mode if there is no operation in 15 minutes to save battery energy.
Press the “ (@), then press the “( (@ J' at the same time to tum on the meter. Auto-off function wil be canceled.

Measurement operation
Auto Mode
/i Don't use it to test voltage over 600V, the meter may be damaged. Always test known voltage with the meter before
using to confirm the instrument function is intact.
1) Long press the “(& " to power on, and the display shows “AUTO”, it defaults AUTO mode. Or Short press “(@A)”
to select AUTO mode.
2) Connect the test leads o the source or load to be measured.
3) The meter automatically recognizes voltage, resistance, and continuiy.
4) Read the measurement result from the display.
Note: If the resistance value of the measured resistor or circut is less than 5000, the buzzer will beep and the green
backlight will be lt.
NCV measurement,
1) Short press the (@) button to switch to NCV function.The meter will display “NCV”.
2) Then NCV probe gradually approaches the detected point.
3) When the meter senses weak AC signals, the green backlight lits and meter beeps slowly.The display shows
4) When the meter senses strong AC signals, the red backlight lits and meter beeps fast. The display shows “~

LIVE measurement
1) Short press the “@&)" button to switch to LIVE function.The meter will display “Live”.
2) Connect the red tst lead to the test point
3) When the meter senses weak AC signals, the green backlight lits and meter beeps slowly. The display shows “~
4) When the meter senses strong AC signals, the red backlight lits and meter beeps fast. The display shows “~
Phase Measurement
1) Short press the @ button to switch to Phase function. The meter will display “Phase”.
® The display flashes To show the “PA” symbol (“A” flashes), place the NCV sense probe against the first phase wire.
@ The display flashes to show the “PAB” symbol (“A” is fixed, “B” Is flashing), place the NCV sense probe against the
second phase wire.
@ The display flashes the “PABC” symbol (“A”and “B” fixed, “C” flashing), place the NCV sense probe against the third
phase wire.
2) The test is finished and the measurement result is shown on the display:
“P ——— L symbol s on the display indicates phase sequence left rotation;
R symbol is on the display indicates phase sequence right rotation
-
Note:
® Keep the sensing probe close to the wire.

@ Shielded wires/cables, thickness, type of insulation, or complete insulators have an effect on the detection
@ Ploase complete the test on the three lines within 1 minute, otherwise, a detection timeout error will occur, prompted
by the PABC symbol and the P letter flashing. When the timeout error occurs, please return to phase sequence
detection to re-test.
® When the three~phase lines are very close, as far as possible separate the lines to detect, otherwise it is easy to
misjudge.

Maintenance
Clean
AIf there's dust on the terminal or the terminal is wet, it may cause measurement error. Please clean the instrument
‘according to the steps below:
® Switch off the power supply.
® Wipe the outer cabinet with a dam cloth and mild detergent. Wipe contacts in each input terminal with a clean cotton
swab soaked in aicohol.
AN WARNING
Always keep the inside of the instrument clean and dry to avoid electric shock or instrument damage.
Remove and Replace the Battery
1) Tum off the power to the meter.
2) Remove the battery cover by unscrewing the screw that holds the battery cover with a screwdriver.
3) Remove the old battery and replace it with a new one of the same size, please pay attention to the battery polarity,
there are positive and negative polarity marks for each battery in the battery box.
4) Put the battery cover back to its original position and use the screws to fix the battery cover and lock it tightly.
WARNING
@ In order to avoid wrong reading which may lead to electric shock or personal injury, please replace the battery
1

immediately when the battery power is low.
@ Do not discharge the battery by short-circuiting It or reversing its polarity.
@ To ensure the safe operation and maintenance of this meter, remove the batteries when not in use for a long period of
ime to prevent damage to the product from battery leakage.
