Safety Information
• The 38XR-A Digital Multimeter is UL, CSA, and EN61010-1 certified for
Installation Category III – 1000V and Category IV – 600V. It is recommended
for use with fixed equipment installations, such as, distribution panels, feeders
and short branch circuits and lighting systems in large buildings; and for the
primary supply level, such as, an electric meter or an overhead or underground
utility service.
• 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.
