• Use extreme caution when working with high voltages.
• Do not measure voltage if the voltage on the “COM” input jack exceeds
1000V above earth ground.
• Never connect the meter leads across a voltage source while the function
switch is in the current, resistance or diode mode, doing so can damage
the meter.
• Always discharge filter capacitors in power supplies and disconnect the
power when making resistance or diode tests.
• Always turn off the power and disconnect the test leads before opening
the covers to replace the fuse or batteries.
• Never operate the meter unless the back cover and the battery and fuse
covers are in place and fastened securely.
• If the equipment is used in a manner not specified by the manufacturer,
the protection provided by the equipment may be impaired.
