2. INSTALLATION
2.1 Preliminary Tests
Prior to installation, each tilt beam should be checked for proper operation by completing the
following:
1)
Connect the beam to a readout or datalogger. (See Section 3 for readout and datalogger
instructions.)
2)
Depending upon which version of the tilt beam was purchased, hold the beam in a strictly
horizontal or vertical position. The beam must be held in a steady position while taking
readings. The observed reading should be close to the factory zero reading provided on the
calibration report.
(Note that the RB-500 Readout Box uses a 2:1 voltage divider to halve
the full-scale output of the MEMS sensor, which is ±4 volts. This is done so that the ±2
volt DVM in the RB-500 readout box can display the full output range of the MEMS
sensor.)
3)
At one end of the beam there is a label that shows the sign of the change in readout voltage
when that end of the beam is tilted in the direction shown. Tilts in a positive direction (+)
should yield increasing readings. Tilts in a negative direction (-) should yield decreasing
readings. The temperature indicated on the readout should be close to ambient.
4)
Repeat this process with the remaining beams.
Should any of these preliminary tests fail, see Section 5 for troubleshooting.
2.2 Attaching Mounting Brackets
Each beam is supplied with mounting brackets and associated hardware (Figure 2). To mount the
brackets to the beam: Slide the external tooth lock washers (D) onto the bolts (C), followed by
the flat washers (E). Use the bolts to attach the mounting brackets to the ends of the beam. Figure
3 shows the completed assembly.
