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 Protection Limits
Function Maximum
Input
V DC or V AC
1000 VDC/AC rms
mA AC/DC
500 mA 1000V fast acting fuse
A AC/DC
10A 1000V fast acting fuse (20A for 30 seconds
max every 15 minutes)
Frequency, Resistance, Capacitance,
Duty Cycle, Diode Test, Continuity
1000 VDC/AC rms
Temperature 1000
VDC/AC
rms
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.
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 covers to
replace the fuse or batteries.
7.
NEVER
