Introduction The Fluke 233 (hereafter the Meter) is a compact and easy to operate tool for electrical and electronic circuit measurements. XWWarning Read "Safety Information" before you use the Meter.
233 Getting Started Manual Safety Information The Meter complies with: • • • • • • • • • ISA-82.02.01 CAN/CSA C22.2 No. 61010-1-04 ANSI/UL 61010-1:2004 EN 61010-1:2001 EN 61326-1:2006 EN 61326-2-2:2006 ETSI EN 300 328 V1.7.1:2006 ETSI EN 300 489 V1.8.1:2008 FCC Part 15 Subpart C Sections 15.207, 15.209, 15.
True-rms Remote Display Digital Multimeter Safety Information • Remove the test leads from the Meter before the battery door on the Meter base is opened. • Examine the test leads for damaged insulation or exposed metal. Measure the test leads for continuity. Replace damaged test leads before you use the Meter. • Do not apply more than the rated voltage, shown on the Meter, between the terminals or between a terminal and earth ground.
233 Getting Started Manual • 4 Use only specified 1.5-V AA batteries (three in the Meter base and two in the display), correctly installed, for Meter power. • Comply with local and national safety requirements when in hazardous locations. • Only use test leads that have the same voltage, category, and amperage ratings as the Meter and that are approved by a safety Agency. • Measure a known voltage first to make sure that the Meter operates correctly. If you are unsure, have the Meter examined.
