• Do not measure a capacitor that is not fully
discharged. Connecting a charged or partially
charged capacitor to the input terminals will
damage the instrument.
• When measuring within a circuit, the circuit must be
de-energized before connecting the test leads.
• When used in a dusty environment, the instrument
should be wiped and cleaned regularly.
• Do not leave the instrument exposed to direct heat
from the sun for long periods of time.
• Before removing the cover, ensure that the
instrument is disconnected from any circuit and is
powered OFF.
