Page 11: Description
1.4 DESCRIPTION The Megohmmeters Models 6526 and 6534 are portable measuring instruments with digital displays. They are powered by batteries. These instruments can check the safety of electrical installations. For example, they can be used to test new installations before they are powered up, check an existing installation in a power-off condition, or troubleshoot an installation. -
