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.

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.
