1.5 Impaired Safety

Whenever it is likely that safety has been impaired, the Analyzer must be turned off and disconnected from line power. The matter should then be referred to qualified technicians. Safety is likely to be impaired if, for example, the Analyzer fails to perform the intended measurements or shows visible damage.

1.6 General Safety Information

Warning

Removing the Analyzer covers or removing parts, except those to which access can be gained by hand, is likely to expose live parts and accessible terminals which can be dangerous to life.

The Analyzer shall be disconnected from all voltage sources before it is opened.

Capacitors inside the Analyzer can hold their charge even if the Analyzer has been separated from all voltage sources.

When servicing the Analyzer, use only specified replacement parts.

1.7 Safe Handling and Use of Li-ion battery pack

The Analyzer uses a rechargeable Li-ion battery pack model BP290 (26 Wh, standard) or BP291 (52 Wh, optional).

For instructions how to safely handle and use this battery pack refer to Chapter 1, General Aspects, Paragraph ‘Safe Use of Li-ion Battery Pack’ in the Users Manual of Fluke 434-II/435-II/437-II.

The Users Manual can be downloaded from Fluke’s website.
