The new safety standard for 2 pole voltage indicators has just come into force and the updated Martindale VI-13800 is fully compliant.
Safe electrical work requires the use of a voltage indicator that has been proved with a proving unit. Voltage indicators should always be tested with a proving unit or known live source before and after use. This combined unit guarantees a proving device is always available.
