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
1000VDC/AC rms
mA AC/DC
800mA 1000V fast acting fuse
A AC/DC
10A 1000V fast acting fuse (10A for 30 seconds
max every 15 minutes)
Frequency, Resistance,
Capacitance, Diode Test,
Continuity
600VDC/AC rms
Temperature
600VDC/AC rms
Surge Protection: 8kV peak per IEC 61010
2.
USE EXTREME CAUTION
when working with high voltages.
3.
DO NOT
measure voltage if the voltage on the "COM" input jack exceeds 1000V 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
operate the meter unless the back cover and the battery and fuse covers are in
place and fastened securely.
8. If the equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
