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
600V DC/AC, 200Vrms on 400mV
range
mA AC/DC
500mA 250V fast acting fuse
A AC/DC
20A 250V fast acting fuse(30
seconds max every 15 minutes)
Frequency, Resistance,
Capacitance, Duty Cycle,
Diode Test, Continuity
250Vrms for 15sec max
Temperature
60V DC/24V AC
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.
DO NOT measure current of circuits whose voltage is greater
than 500V above earth 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 disconnect the test leads
before opening the cover to replace the fuse or battery
7.
NEVER operate the meter unless the back cover is in place
and fastened securely
