    (LCD), a power on/off switch, an A/B selector switch, a battery charger circuit, an AC adaptor connector, and a 10-pin Bendix connector and a terminal strip. The RB-500 instrument supplies +12V power to the MEMS sensor and displays the output in Volts which is proportional to the sine of the angle of inclination.

    2. INCLINATION MEASUREMENT Complete the following steps: 1) Connect the MEMS Sensor to the readout box by means of the 10-pin plug or, if bare leads, by means of the terminal strip on the face panel following the printed color code on the panel.

    G = The gauge factor, (sin θ/volt) or (degrees/volt) from the calibration report provided with the sensor. (A sample calibration report is provided in Appendix C.) = The initial reading in volts as displayed on the RB-500 = The current readings in volts as displayed on the RB-500.

    3. MAINTENANCE 3.1 General Maintenance Keep the following points in mind when using the RB-500 MEMS Sensor Readout to maximize reliability and accuracy of the unit. The readout box is splash proof, but it will not withstand complete immersion in water.

  • Page 9: Trouble Shooting

    4. TROUBLE SHOOTING If the readout box fails to put out any power, it may be because the 12-volt power lead was inadvertently shorted to ground. To check, remove the face plate and replace the 6/10 Amp fuse to be found in the fuse holder. Additional fuses are included with a new readout box. If the readout box fails to power up it may be that the internal two-amp fuse has blown.
