WARNING AND PRECAUTIONS

The DM2 is not recommended for high voltage industrial use appli-

cations, but for use with low energy circuits to 500VAC or 1000VDC,

or high energy circuits only to 250 VAC or VDC. ■ Do not exceed the

maximum overload limits per function (see specifications) nor the

limits marked on the instrument itself. ■ Exercise extreme caution

when: measuring voltage >20 V / / current >10mA / / AC power line

with inductive loads / / AC power line during electrical storms / / cur-

rent, when the fuse blows in a circuit with open circuit voltage > 600

V / / servicing CRT equipment. ■ Inspect DMM, test leads and

accessories before every use. Do not use any damaged part. ■ Never

ground yourself when taking measurements. Do not touch exposed

circuit elements or probe tips. ■ Always measure current in series

with the load – NEVER ACROSS a voltage source. Check fuse first.

■ Never replace a fuse with one of a different rating. ■ Do not oper-
