4.1 Cleaning
If foreign matter gets stuck between the tips of the clamp sen-
sor, do not forcibly open or close the clamp sensor, but rather
use a soft brush or similar implement to carefully remove the
foreign matter. Accurate measurements 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 instrument
inspected and calibrated by your dealer.
• Wipe the LCD gently with a soft, dry cloth.
• To clean the instrument, wipe it gently with a soft cloth
moistened with water or mild detergent. Never use sol-
vents such as benzene, alcohol, acetone, ether,
ketones, thinners or gasoline, as they can deform and
discolor the case.
