NHS approval for Martindale voltage tester
Martindale’s VI137002 voltage tester is approved as a standard tester for its estates and facilities division, according to ‘Health technical memorandum 06-02:electrical safety guidance for low voltage systems’. The memorandum states that all work on low-voltage electrical equipment, including conductors, should be carried out while such electrical equipment and conductors are dead and isolated from all sources of supply — and after being proved dead at the point of work.
The VI137002 can be used to indicate a voltage range from 50 to 400 V. It automatically detects AC/DC and responds to voltage presence within 100 ms.
