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-
ate instrument in an explosive atmosphere.
