Applications
The instrument is capable of measuring
direct and alternating current, and is
equipped with a connectable current clamp.
In the case of direct current measurement,
conventional current clamps are not capable
of performing accurate measurement in the
light current range due to influences resulting
from magnetization and geomagnetism. This
device is a current clamp measuring
instrument which is capable of very accurate
measurement of direct and alternating
current thanks to the use of highly sensitive
materials and a magnetization method.
Attention!
!
The specified maximum input
quantities may not be exceeded in
order to prevent damage to the
instrument and injury to the user:
voltage range: 600 V AC/DC,
current range: 10 A AC/DC.

Initial Start-Up
Batteries
Your instrument requires four 1.5 V batteries
(size AA) in accordance with IEC LR6.
Make sure that no battery leakage has
occurred before initial start-up, as well as
after long periods of storage. Continue to
inspect the batteries for leakage at short,
regular intervals.
If battery leakage has occurred, carefully and
completely clean the electrolyte from the
instrument with a damp cloth, and replace
the batteries before using the instrument.
If the “
B
” symbol appears at the LCD panel,
the batteries should be replaced as soon as
possible.
Battery Replacement
Attention!
!
Disconnect the current clamp from
the measuring circuit before opening
the device in order to replace the
batteries!
Remove the screw from the battery
compartment lid with a screwdriver. Push
the battery compartment lid in the direction
indicated by the arrow and remove it.
Remove the 4 batteries and replace them.
Return the battery compartment lid to its
original position and tighten the screw.
Do not use battery sets consisting of old and
new batteries, or batteries with different
brand names.
