  • Page 19: Measuring

    AVL DiTEST DPM 800 Measuring Measuring Taking a reading Switch off the vehicle's engine. Unscrew the sparkplug (glow plug). Carefully feed the lead for the piezo-electric pressure-sensing sparkplug (glow plug pressure sensor adaptor) through the adaptor socket (A). In the adaptor socket there is a slot (B) through which the lead can pass through the socket without being damaged.
  • Page 20 Take care not to cross the thread when screwing on the lead. Fig. 3-2 Screw the lead from the AVL DiTEST DPM 800 power supply unit SIGNAL OUT connection (E) to the AVL DiTEST DPM 800 amplifier (D), see Fig. 3-3.
  • Page 21 Measuring Connect the CH1 connection on the AVL DiScope 802 to the SIGNAL OUT socket on the AVL DiTEST DPM 800 power supply unit using the connecting lead (F), see Fig. 3-4. Fig. 3-4 Connect the on-board engine speed/TDC sensor to connection CH2 (I) on the AVL DiScope 802.
