This symbol, adjacent to another symbol or
terminal, indicates the user must refer to the
manual for further information.

This symbol, adjacent to a terminal, indicates that,
under normal use, hazardous voltages may be
present

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.

WARNINGS

Set function switch to the appropriate position before

measuring.

When measuring volts do not switch to

current/resistance modes.

When changing ranges using the selector switch always

disconnect the test leads from the circuit under test.

Do not exceed the maximum rated input limits.

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.
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.
Remove the battery if the meter is to be stored for long
periods.
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.
