1. Safety

1.1. Safety Instructions

• This meter has been designed for safe use, but must be operated with

caution.

• The instructions 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.

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 cover to replace the fuse or batteries.

7. Never operate the meter unless the back cover, 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.

which if not avoided, may result in damage to the product.

This symbol advises the user that the terminal(s) so marked must

MAX

not be connected to a circuit point at which the voltage exceeds

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 insulation or reinforced insulation. This symbol indicates

that a device is protected throughout by double insulation or
