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

Maximum Input

V DC or V AC

1000 VDC/AC rms

mA AC/DC

500 mA 1000V fast acting fuse

A AC/DC

10A 1000V fast acting fuse (20A for 30 seconds

max every 15 minutes)

Frequency, Resistance, Capacitance,

Duty Cycle, Diode Test, Continuity

1000 VDC/AC rms

Temperature

1000 VDC/AC rms

2.

USE EXTREME CAUTION when working with high voltages.

3.

DO NOT measure voltage if the voltage on the "COM" input jack exceeds 600V 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 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.
