SAFETY NOTES

• Do not exceed the maximum allowable input range of any function.

• Do not apply voltage to meter when resistance function is selected.

• Set the function switch OFF when the meter is not in use.

• Remove the battery if meter is to be stored for longer than 60 days.

WARNINGS

• Set function switch to the appropriate position before measuring.

• When measuring volts do not switch to current/resistance modes.

• Do not measure current on a circuit whose voltage exceeds 600V.

• When changing ranges always disconnect the test leads from the circuit under test.

• Changes or modifications to this unit not expressly approved by the party

responsible for compliance could void the user's authority to operate the
equipment.
Note: This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide
reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if
not installed and used in
accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in
a particular installation. If this equipment does cause harmful interference to redio
or television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct
the interference by one or more of the following measures:

Reorient or relocate the receiving antenna
Increase the separation between the equipment and receiver
Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected
Consult the dealer or an experienced radio/TV technician for help.

The device must not be co-located or operating in conjunction with any other

antenna or transmitter.

CAUTIONS

• Improper use of this meter can cause damage, shock, injury or death. Read and
understand this user manual before operating the meter.

• Always remove the test leads before replacing the battery or fuses.

• Inspect the condition of the test leads and the meter itself for any damage before

operating the meter. Repair or replace any damage before use.

• Use great care when making measurements if the voltages are greater than 25VAC
rms or 35VDC. These voltages are considered a shock hazard.

• Always discharge capacitors and remove power from the device under test before
performing Diode, Resistance or Continuity tests.

• Voltage checks on electrical outlets can be difficult and misleading because of the
uncertainty of connection to the recessed electrical contacts. Other means should
be used to ensure that the terminals are not "live".

• If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
