    Then energised, moving parts remain in their current position. Operational environment All DTM7000 modules should be installed in a clean, dry location, free of dust, water vapour and combustion fumes. The equipment requires a lighting level of approximately 400 to 500 Lux.

  • Page 4: The Basics Of Electricity

    DTM7000 2. THE BASICS OF ELECTRICITY Reminder of the Basics of Electricity Voltage. The Volt is used to measure Voltage (also known as 'potential difference' or 'pd), which is defined as the work done per unit charge in order to move that charge from one point to another. The symbol used for voltage is V, and its unit is the Volt.
  • Page 5 The device should never be connected to an external power supply.  Components to be measured must be disconnected from the circuit and powered-down.  Avoid disrupting readings by touching the circuit with any part of your body (which is a conductor). Site: exxotest.com...

  • Page 6: Vehicle Power Supply

    DTM7000 Vehicle power supply Vehicles are fitted with batteries, which work as chemical storage devices for the electrical energy produced by the vehicle's generator (alternator). The batteries must be capable of providing rapid high current supplies (above all, at low temperatures) when starting the vehicle cold and providing partial or total supply to the other major loads throughout the vehicle's electrical system for a limited period, above all when the vehicle's engine is running at idle or has been stopped.
