SAFETY INSTRUC TI ONS
This m eter has bee n des i gn ed for safe us e, bu t mus t be operated
with caution. The rules listed below must be carefully followed for
safe op eration.
1. NEVER apply voltage or current to the meter that exceeds the
spec ifi e d max imum :
Input Lim its
Function Maximum Input
V DC or V AC 600V DC/AC, 200Vrms on 200mV
range
mA AC/DC 200mA 250V fast acting fuse
A AC/DC 20A 250V fast acting fuse(30
sec onds m ax every 1 5 minutes )
Resistance, Diode Test,
Continuity
Temperature 60V DC/24V AC
2. USE EXTREME CAUTION when working with high voltages
250Vrms for 15 sec max
3. DO NOT measure voltage if the voltage on the "CO M" input
jack exceeds 600V above earth ground
4. DO NOT measure current of circuits whose voltage is greater
than 60 0V ab ov e ear t h ground
5. NEVER connect the meter leads across a voltage source
while the function switch is in the resistance or diode mode.
Doing so can damage the meter
6. ALWAYS turn off the power and dis c onnec t the tes t le ads
before opening the cover to replace the battery
7. NEVER oper a te th e meter unless the bac k cov er is in place
and fastened secure ly
