1.Safety

1-1. 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:
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 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.
8.If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.

1-2. 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.
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) 600 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 insu-
lation or reinforced insulation.
