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:
Function Maximum Input
VAC 600V DC/AC
V DC or V AC 600V DC/AC, 200Vrms on 200mV range
mA DC 200mA 250V fast acting fuse
A DC 10A 250V fast acting fuse(30 seconds max
Resistance, Continuity 250Vrms for 15sec max
2. USE EXTREME CAUTION when working with high voltages.
3. DO NOT measure voltage if the voltage on the "COM" input jack
exceeds 500V 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 doors to replace the fuse or batteries.
7. NEVER operate the meter unless the back cover and the battery and
fuse doors are in place and fastened securely.

SAFETY SYMBOLS
This symbol adjacent to another symbol, terminal or
operating device indicates that the operator must refer
to an explanation in the Operating Instructions to avoid
personal injury or damage to the meter.
WARNING
CAUTION
MAX
500V
This WARNING symbol indicates a potentially
hazardous situation, which if not avoided, could result
in death or serious injury.
This CAUTION symbol indicates a potentially
hazardous situation, which 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
exceeds (in this case) 500 VAC or VDC.
This symbol adjacent to one or more terminals
identifies them as being associated with ranges that
may, in normal use, be subjected to particularly
hazardous voltages. For maximum safety, the meter
and its test leads should not be handled when these
terminals are energized.
This symbol indicates that a device is protected
throughout by double insulation or reinforced insulation.
