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 Limits

Function

Maximum Input

V DC or V AC

1000V DC, 700V AC

mA DC/AC

200mA DC/AC

A DC/AC

20A DC/AC (30 seconds max every 

15 min.)

Resistance, Capacitance,  

Continuity, Diode

250V DC/AC rms

2.   USE EXTREME CAUTION

 when working with high voltages.

3.   

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.

4.   

ALWAYS

 discharge filter capacitors in power supplies and disconnect 

the power when making resistance or diode tests.

5.   

ALWAYS

 turn off the power and disconnect the test leads before open-

ing the covers to replace the fuse or batteries.

6.   

NEVER

 operate the meter unless the back cover and the battery and 

fuse covers are in place and fastened securely.
