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.
