• Remaining endangerment: When an input terminal is connected

to dangerous live potential it is to be noted that this potential at
all other terminals can occur!

• CATII - Measurement Category II is for measurements performed

on circuits directly connected to low voltage insta I lation. (Exam
pies are measurements on household appliances, portable tools
and similar equipments.) Do not use the meter for measurements
within Measurement Categories III and IV.

CAUTION

To avoid possible damage to the meter or to the equipment under

test, follow these guidelines:

• Disconnect circuit power and discharge all high-voltage

capacitors before testing resistance,diode and continuity.

• Use the proper function and range for your measurements.

• Before moving the rotary switch to change functions, disconnect

test leads from the circuit under test and remove the clamp jaws
from the clamped conductor.
