SAFETY INSTRUCTION S
This m eter has been designed for saf e us e, but mus t 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, V AC 600V DC and 600V AC
mA AC/DC 200mA AC/DC
A AC/DC 10A AC/DC (for 15 seconds max.
every 15 minutes)
Resistan ce, Diode Test,
500V AC/DC
Continuity
Frequency 250V AC/DC
2. USE EXTREME CAUTION whe n working with h igh
voltages.
3. DO NOT measure voltage if the volt age 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 mod e. Doi ng so can damage the meter.
5. ALWAYS discharge filter capacitors in power supplies and
disc on nec t th e pow er when making resis ta nc e or d io de
tests.
6. ALWAYS turn off power and disconnect test leads before
opening the covers to replace the fuse or battery.
7. NEVER oper a te th e meter u nles s t he bac k cov er is in plac e
and fasten ed securel y.

This CAUTION symbol indicates a
poten tially hazardous si t u ati on , whic h if not
avoided, may result damage to the product.
This symbol advises the user that the
terminal(s) so marked must not be
connected to a circuit point at which the
voltage with respect to earth ground
exc eeds 60 0V .
This sy m bo l ad jac e nt to on e or mo re
terminals identifies them as being
associated with ranges that may, in normal
use, be sub jec t ed t o part icul arly haz ardous
voltages. For maximum safety, the meter
and its test leads should not be handled
when these terminals are energized.
This symbol indicates th at a device is
protected throughout by double insulation or
reinforced ins ul ati on.
