Safety

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 Limits

Function

Maximum Input

V DC, V AC

600V DC/AC, 200Vrms on 200mV range

mA DC

200mA 250V fast acting fuse

A DC, A AC

10A 250V fast acting fuse(30 seconds

max every 15 minutes)

Resistance,

Continuity

250Vrms for 15sec max

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.
