Figure 2 - Model 6161 Tilt Sensor
2 INSTALLATION
2.1. Preliminary Tests
Prior to installation, the sensors need to be checked for proper operation. Each tilt sensor is
supplied with a calibration sheet, which shows the relationship between output voltage and
inclination. The tilt sensor electrical leads are connected to a Datalogger or the RB-500 readout
box (see section 3) and the current reading compared to the calibration readings. Carefully hold
the sensor in an approximately vertical position and observe the reading. The sensor must be
held in a steady position. The readings should be close to the factory vertical reading. The
temperature indicated by the thermistor should be close to ambient.
Checks of electrical continuity can also be made using an ohmmeter. Resistance between any
conductor and the shield or the case should exceed 2 megohm.
