Safety Notes

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

 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.

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

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

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.

 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.
