• For safety reasons, use the instrument under a low-voltage circuit of AC600V or less. Check the circuit voltage before measurement. • Do not clamp any bare wire. • Do not measure when the CT or the body is damaged nor the battery cover is removed. • Do not operate with wet hands, including when battery replacement. Also do not use in extremely humid places or when the instrument body is wet as well. • Do not disassemble or modify the instrument. CAUTION • Wipe the instrument gently with a soft cloth moistened with a small amount of water or neutral detergent, when it gets dirty. Do not use any abrasives ...

greatly improved convenience using the latest technology. Features • Since the influence from the external magnetic field is slight, a minute current can be measured accurately even near a motor or other wiring. • The iron core made of a special alloy that does not rust for a long time use provides less aging stable accuracy. • The filter function allows you to know the amount of high frequency content in the leakage current. • This instrument has a Bluetooth communication function. It communicates with a smartphone / tablet with the dedicated application "Mu ...
