 Do not use the meter in the presence of explosive gas or vapor.
 To reduce risk of fire or electric shock, do not use the meter if it is wet and do not expose the meter to
moisture.
 Individual protective equipment should be used if HAZARDOUS LIVE parts in the installation where
measurements are to be carried out could be accessible.
CAUTIONS
CAUTIONS identify conditions and actions that could cause DAMAGE to the meter or equipment
under test. Do not expose the meter to extremes in temperature or high humidity.
 Disconnect the test leads from the test points before changing the position of the function (rotary)
switch.
 Do not expose the meter to extremes in temperature or to high humidity.
 Never set the meter to the resistance, diode, capacitance, or amp functions when measuring the
voltage of a power supply circuit; this could result in meter damage and damage to the equipment
under test.
