Check your insulation according to the applicable standards
With its double digital display, two-colour backlighting, ditrect access to the functions and shockproof sheath, the ergonomic design of the CA 6528 insulation tester and multimeter makes it particularly easy to use. Not to mention the fact that the visual alarm indicates the test result simply by the colour of its backlighting. If the continuity measurement at 200 mA is OK, the screen is blue. If the result is > 2 Ω, the screen turns red.
