Safety Information
- Use the instrument only as specified in this
manual or the protection by the instrument
might be impaired.
- Always use proper terminals, switch position,
and range for measurements.
- Verify the instrument’s operation by measure
ing a known voltage. If in doubt, have the
instrument serviced.
- Do not apply more than the rated voltage,
as marked on the instrument.
- To avoid false readings that can lead to
electric shock and injury, replace battery as
soon as low battery indicator.
- Do not use the instrument around explosive
gas or vapor.
- To reduce the risk of fire or electric shock
do not expose the instrument to rain or
moisture.
- Individual protective equipment should be
used if HAZARDOUS LIVE parts in the
installation where measurement is to be
carried out could be ACCESSIBLE.
- Do not allow fingers to protrude beyond
the Tactile Barrier when fitting or removing
the instrument from around a Hazardous
Live conductor, as this may cause a shock.

Auto ACA&DCA Detection / ACA&DCA
Due to the high sensitivity of the instrument,
perform DCA Zero in the same direction as
measurement to avoid interference by an
external magnetic field.
6
Data Hold
The display will flash continuously if the measured
signal is larger by 50counts than the display
reading. However, it cannot detect across the AC
and DC Current.

The instrument calculates the RMS value for
100ms as detecting a more than 5A current.
