Section 5 Scanner ® 2000 microEFM MVT Replacement Important Press the ENTER/SAVE key on the keypad before disconnecting the battery to save accumulated flow run and turbine volume totals (grand total and current day total), and energy and mass totals to memory. To replace the MVT of the Scanner 2000, perform the following steps: 1. Unscrew the cover of the enclosure counter-clockwise until it separates from the main body of the enclosure. 2. Using a small standard blade screwdriver, remove the two #4-40 × 7/8” screws located to the right and leftside of the display (Figure 5.1, page 76). 3. Lift the display/keypad assembly from the enclosure. 4. Unplug the battery cable from connector J1 on the circuit board. 5. Disconnect the sensor ribbon cable from the J5 connector on the circuit board as follows: 80 a. Lift the latch from the black clip securing the ribbon cable (Figure 5.2, page 77). b. When the latch is fully open, the ribbon cable will release freely. 6. Loosen the set screw in the side of the MVT adapter. 7. Rotate the adapter counterclockwise to break the connection with the MVT sensor body. 8. Detach the MVT sensor from the adapter, pulling the ribbon cable free. 9. Remove the replacement MVT from its packaging and route the ribbon cable through the adapter and up into the Scanner 2000 enclosure. 10. Screw the MVT into the adapter until it meets with resistance. 11. Slowly unscrew the MVT sensor until the vents on the sides of the MVT are oriented to the back of the enclosure. 12. Replace the set screw in the adapter and tighten. 13. Connect the ribbon cable from the sensor to the MVT connector (J5) on the main circuit board. 14. Reconnect the battery cable to connector J1 on the main board. 15. Reinstall the display/keypad assembly in the enclosure, using the screws that were removed in step 2. 16. Recalibrate the Scanner 2000 and replace the cover on the enclosure. Important Do not overlook the need to recalibrate the Scanner 2000. MVTs that are shipped independently of a Scanner 2000 are not calibrated to compensate for atmospheric pressure; therefore, a Scanner 2000 will not display accurate pressure readings until it is recalibrated.
