SAFETY INSTRUCTIONS

This meter has been designed for safe use, but must be operated with
caution. The rules listed below must be carefully followed for safe operation.
1. NEVER apply voltage or current to the meter that exceeds the
specified maximum:
Function
VAC
V DC or V AC
mA DC
A DC
Resistance, Continuity
2. USE EXTREME CAUTION when working with high voltages.
3. DO NOT measure voltage if the voltage on the "COM" input jack
exceeds 500V above earth ground.
4. 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.
5. ALWAYS discharge filter capacitors in power supplies and disconnect
the power when making resistance or diode tests.
6. ALWAYS turn off the power and disconnect the test leads before
opening the doors to replace the fuse or batteries.
7. NEVER operate the meter unless the back cover and the battery and
fuse doors are in place and fastened securely.
