2.3 Sensor Installation
2.3.1 Installing Uniaxial Tiltmeters
Attach the tiltmeter to the mounting bracket using the supplied 10-32 cap screws,
washers, and nuts.
Remove the slotted head locking clamp screw completely and
replace with the Phillips head seal screw (provided). This is very important if the
sensor is to remain waterproof.
Do not tighten the cap screws yet. Attach a portable
readout such as the GK-404 or GK-405 (see Section 3 for readout instructions) and
observe the reading. Adjust the sensor in the slot of the mounting bracket while observing
the readout until the tiltmeter reads within
±
50 digits of the zero reading as shown on the
calibration report supplied with the sensor. (See Appendix A for a sample calibration
report.) When the desired reading is reached, tighten the cap screws to secure the
tiltmeter in place. Check the reading again after tightening to make sure it still reads
within
±
50 digits of the zero reading. Figure 6 shows the completed installation.
If the tiltmeter is installed in an exposed location in a construction area, and/or if the
installation is in direct sunlight, it should be covered with a protective enclosure and/or
insulation.
