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 

VAC 

600V DC/AC 

V DC or V 
AC 

600V 

DC/AC, 

200Vrms 

on 

200mV range 

mA DC 

200mA 250V fast acting fuse 

A DC 

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.
