XWSafety 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 600 VDC
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 >20 V // current >10 mA //
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.
