    INTRODUCTION Multimeter Tutorial MULTIMETER The Multimeter The multimeter is one of the most useful tools in the toolbox. It can be used to check wires, shorts, voltages, resistance, all manner of electrical circuits. This tutorial is designed to help clarify the symbols and socket op- tions found on various multimeters.

  • Page 9: Symbols

    INTRODUCTION Symbols This section describes the basic symbols used in a typical multimeter. This symbol means alternating current. Use this when you want to test something that has AC current running through it. Typically you’d want to test the voltage of an inverter (for cold cathodes or neons) or a similar device. This means Direct Current.

  • Page 106 SEATING SECTION Connect a meter to the 2 pins indicated in the Fig 3.99 photo (Fig 3.99). Check continuity through the switch by pressing in on the CRS plunger. Note, when the seat-back is in the full up position the switch should be open. When the seat lowers the switch should close.

  • Page 107: The Recline Actuator Will Not Run, Or Runs Erratically

    To test the current drain and operation of the en- coder switches of the Recline actuator, complete the Fault Isolation Procedures Using Quickie iQ or HHP located in this manual. Replace the Recline actuator if the procedure fails. To continue testing, complete the following procedures.

    To test the current drain and operation of the encoder switches of the Shear actuator, complete the Fault Isolation Procedures Using Quickie iQ or HHP. Replace the shear actuator if the procedure fails. To continue testing, complete the following procedures.
  • Page 109 SEATING SECTION Check armature resistance through the pins indi- Fig 3.107 cated in the photo (Fig 3.107). Nominal resistance is 6 to 8 ohms when the actuator is in mid-stroke and greater than 1 MΩ when at either extremity. If the resistance is open, follow the cable to an- Fig 3.108 other cable leading to the actuator.

  • Page 110: Adjustments

    Adjustments of the New Recline for the seat-pan are Fig 3.109 similar to the old Perfect Fit Recline. Refer to that por- tion of the Rhythm and Groove Tech Service Manual for those procedures. Adjustments for the seat-back are simpler than the old Perfect Fit Seating System.
  • Page 111 SEATING SECTION Seat-back depth is adjusted by moving the mount- Fig 3.112 ing brackets to the front or rear in the seat-pan track. Loosen the two mounting bolts (C) and slide the bracket to the desired location (Fig 3.112). To adjust the arm rest hanger, loosen the two Fig 3.113 mounting bolts (D) and slide the mount to the desired location (Fig 3.113).

  • Page 113 SEATING SECTION Once both screws are loosened, lift the QR-MAC Fig 3.118 mount up and place it to the side (Fig 3.18). WARNING During the next steps, you will be removing the Gas Strut. It is under pressure. Be sure to use caution when removing the Recline Actuator from the chair.
  • Page 114 SEATING SECTION Use a ¼” Hex wrench and a 9/16” open-end Fig 3.122 wrench and remove the top bolt that holds the Re- cline actuator to the back structure (Fig 3.122). Unplug the three connectors to the recline actua- Fig 3.123 tor (two spade connectors (G) with red and green wires, and one 6-pin connector (H)) (Fig 3.123).

  • Page 116: Recline Crs Replacement

    SEATING SECTION Recline CRS Replacement In order to eliminate the re-home switch (previously Fig 3.127 found on the Smart Seat), a separate Counter Reset Switch (CRS) is installed that allows the system to “re- home” during normal operation. This switch is located on the left side of the wheelchair next to the Recline pivot point (Fig 3.127).
