Safety Information
To Avoid possible electric shock, personal injury, damage to the meter or the
equipment under test, adhere to the following practices:
•
Do not exceed the maximum overload limits per function (see specifications)
nor the limits marked on the instrument itself. Never apply more than 600VDC
between the test lead and earth ground.
•
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.
•
Do not operate the instrument in an explosive atmosphere.
•
Exercise extreme caution when measuring voltage >20V // current >10mA // AC
power line with inductive loads // AC power line during electrical storms //
current, when the fuse blows in a circuit with open circuit voltage >600 V //
servicing CRT equipment.
•
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 change the position of the Function/Range Switch while the MIN MAX or
the HOLD feature is enabled. Erroneous readings will result.
•
Remove test leads before opening battery or case to change battery or fuses.
