SAFETY INFORMATION
This meter is a hand-held, battery-operated instrument for testing and
troubleshooting power electronic systems. If this device is damaged or
something is missing, contact the purchasing place immediately.
A WARNING identifies conditions and actions that may cause hazard(s) to the
user; a CAUTION identifies conditions and actions that may damage this
Device. Following Table-1 explain international electrical symbols used on this
meter.

SAFETY INFORMATION
Warnings and Cautions
To avoid electric shock, injury, or damage to this instrument and ensure
that you use the meter safely, follow the safety guidelines listed below:
•Read this operation manual completely before using this device and follow all
safety instructions.
•This device is for indoor use, altitude up to 2,000 m.
•Avoid working alone.
•Use the device only as specified in this manual; otherwise, the protection
provided by the meter may be impaired.
•Never measure Voltage when the current measurement is selected.
•Do not use this device if it looks damaged.
•Inspect the leads for damaged insulation or exposed metal. Replace
damaged leads.
•Disconnect the power and discharge all high-voltage capacitors before
testing in the resistance, continuity, and diode function.
•Be cautions when working above 70V DC or 33VRMS and 46.7V peak, such
voltages may cause a shock hazard.
•Always keep your hands behind the protective guard of the probe as
measuring.
•Select the proper function and disconnect the test leads from test points
before changing functions.
•Always use specified battery.
•The meter is safety-certified in compliance with EN61010 (IEC 1010-1, IEC
1010-2-031) Installation Category ΙV 600V/ III 1000V Pollution Degree 2. In
order to maintain its insulation properties, please be sure to use with the
standard or compatible test probes.
•CE requirement: Under the influence of R.F field according to standard, the
supplied test leads will pick up induced noise. To have better shielding effect,
a short-twisted lead should be used.
