Measurement Procedure

• To avoid electric shock, do not touch the por-
tion beyond the protective barrier during use.
• When the clamp sensor is opened, do not
allow the metal part of the clamp to touch
any exposed metal, or to short between two
lines, and do not use over bare conductors.
• The maximum allowable current is 100 A AC
continuous or 200 A AC for 2 minutes (50/60 Hz). Currents
in excess of these values must be avoided as they may
damage the instrument or cause bodily injury.
• The tips of the clamp sensor are precisely manufac-
tured in order to provide a high level of precision. Exer-
cise caution when handling the clamp so as to avoid
subjecting it to excessive vibration, mechanical shock,
or force.
• If foreign matter gets stuck between the tips of the
clamp sensor, do not forcibly open or close the sensor,
but rather use a soft brush or similar implement to
carefully remove the foreign matter. Accurate mea-
surements cannot be made while foreign matter is
stuck between the tips of the clamp sensor or while the
shape of the clamp sensor is deformed. If the tips of
the clamp sensor become deformed, have the instru-
ment inspected and calibrated by your dealer.
