Safety information for this product
| Before opening the meter, always disconnect all electrical
power sources. Also make sure to discharge yourself since
static electricity could destroy internal components.
| Only qualified technicians who are familiar with these
instructions are permitted to adjust, service or repair the clamp
meter.
| A person is considered qualified when he understands the set-
up, design and functionality of the facility and comprehends
the associated risks. A qualified operator is an experienced
professional who is authorized to switch the power on or off to
circuits within the electrical facility.
| When working with opened devices, remember that internal
capacitors can retain life-threatening voltage levels even after
they have been switched off.
| Stop using the meter if you experience any errors or unusual
operations. Make sure that the meter cannot be used until it
has passed an inspection.
| Remove the batteries if you do not plan on using the meter for
an extended period of time. Do not store the meter in a room
that is overly humid or warm.
| Operate with extreme caution when working around
uninsulated wires and busbars. Touching such components
and wires can lead to electric shock! Make sure that you are
using the appropriate protective mechanisms!
