measurement error.
 Please comply with local and national safety code. Wear personal protection equipment
(such as approved rubber gloves, masks and flame retardant clothes, etc.) to prevent
being damaged by electric shock and electric arc due to exposed hazardous live
conductor.
 The voltage applied between input terminals or between each terminal and earth point
cannot exceed the specified ratings of the instrument.
 Measure a known voltage to determine whether the instrument works properly.
 When measuring, correct input terminal, function shift and range shift must be used.
 Do not use the instrument around explosive gas, steam or in wet environment.
 Do not use damaged probe. Check whether the insulation layer of the probe is damaged,
whether there’s any exposed metal or sign of wear. Check the continuity of the probe.
 When measuring, please connect the zero line or the ground line first, then connect the live
wire; but when disconnecting, please cut off the live wire first, then disconnect the zero line
and ground line.
 When measuring, please keep your fingers behind the finger protector of the probe.
 Before opening the back cover of the instrument, please disconnect the probe from the
measured object.
 Do not use the instrument in the environment of exceeding the measurement category
(CAT) rating of a single element with the lowest rating among the instrument, probe or
accessories.

measuring circuits directly connecting to the supply point
(socket and similarities) of low voltage power supply.
CAT III
CAT III measurement is applicable for testing and
measuring circuits connecting to the distribution section
of building low voltage power supply.
CAT IV
CAT IV measurement is applicable for testing and
measuring circuits connecting to the distribution section
of building low voltage power supply.
