Do not operate the DLM PRO with the battery cover off as this will compromise the insulated safety barrier. To maintain safety, check the tester on a known source or a proving unit such as the Socket & See SP400 before and after use. To ensure serviceability and to monitor accuracy of the DLM PRO, a checkbox such as the Socket &...

The tester will not allow a loop test to be carried out if the socket test function detects a fault or if the incoming voltage is not between 195V and 253V AC. Once the Earth Loop Impedance has been measured the DLM PRO backscreen will illuminate and clear written indication of GOOD, CHECK or FAIL will accompany the numerical value displayed.
