• The 34XR-A Digital Multimeter is UL, cUL, and EN61010-1 certified for
Installation Category III – 600V and Category II – 1000V. It is recommended for
use with local level power distribution, appliances, portable equipment, etc,
where only smaller transient overvoltages may occur, and not for primary
supply lines, overhead lines and cable systems.
• Do not exceed the maximum overload limits per function (see specifications)
nor the limits marked on the instrument itself. Never apply more than 1000V
dc/750 V ac rms between the test lead and earth ground.
• Inspect the 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 test 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 >1000 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.
•
Remove test leads before opening the Battery Cover or case.
