3. 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:

Input Protection Limits

Function

V DC or V AC

mA AC/DC

A AC/DC

Frequency, Resistance,

Capacitance, Duty Cycle, 250VDC/AC RMS

Diode Test, Continuity

Temperature

2. USE EXTREME CAUTION when working with high voltages.

3. DO NOT measure voltage if the voltage on the "COM" input jack

exceeds 1000V above earth.

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 covers to replace the fuse or batteries.

7. 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.
