Page 4: Introduction
The Model 800P Portable Tiltmeter is rugged and field-proven - intended for use outdoors, in the laboratory, and on the factory floor. High-reliability components and surge protection enhance performance under electrically noisy or transient-prone conditions. -
Page 5: Specifications
2.0 Specifications General specifications for the Model 800P Portable Tiltmeter are listed below. Appendix B presents the custom specifications for your instrument. MODEL 800P PORTABLE TILTMETER OUTPUT CHANNELS Inclination (tilt), temperature. ANGULAR RANGE ±5 degrees from null position. RESOLUTION 0.0001 degree (0.36 arc second). -
Page 6: Taking Readings With The Model 870 Readout Module & Multimeter
The Model 870 Readout Module (Figure 4), is designed for use with a hand-held multimeter or voltmeter containing banana plug sockets with standard 0.75 inch center-to- center spacing, such as the multimeter provided with your 800P system. The multimeter/voltmeter serves as the display for your readings. -
Page 7: Reading The Tiltmeter
This can be converted to temperature using the scale factor 100°C/volt. 4.0 Tilt Directions and Sign Convention The model 800P Portable Tiltmeter measures tilt angle in a vertical plane that parallels the tiltmeter handle. When the tiltmeter is viewed from above, labels indicating the (+) and (-) direction of tilt are visible (Figures 1 and 3). -
Page 8: Initial Check-Out Procedure
5.0 Initial Check-Out Procedures Before using your tiltmeter, verify that it is functioning properly by following the steps below: 1) Connect the tiltmeter to your Model 870 Readout Module, and the Readout module to a multimeter/voltmeter as described above. 2) Turn the 870 switch to TILT. 3) Rotate the tiltmeter in the (+) and (-) directions and verify that the sign of the displayed output conforms to this convention. -
Page 9: Obtaining Absolute Angles, Determining Instrument Bias
7.2 Vertical Surfaces The Model 800P is typically used for measuring differences in vertical angle from point to point and, vertical angle changes over time. These are relative measurements, meaning that all readings are referenced to one another rather than to the absolute vertical. -
Page 10: Using The Tilt Plate Option
8.0 Using the Tilt Plate Option 8.1 Installing and Orienting Tilt Plates The Model 800P precisely measures the angular position of tilt plates which have been bonded or fastened to any natural or manmade surface. Jewell Instruments ceramic tilt plates (part no. -

8.2 Taking Measurements from Horizontal Tilt Plates The tilt plate log sheet in Appendix C is designed to assist you in recording your readings, and applying the check-sum method. Copy the log sheet and prepare a log book of blank copies. -
Page 12: Readings In 2-4 Direction
Alternatively, you may use a Jewell Instruments Model 719 Universal Mounting Bracket. This bracket attaches to a vertical surface and has a horizontal shelf. A tilt plate mounted on the shelf enables you to make biaxial measurements. -
Page 13: Using The Metrology Option
Now rotate the tiltmeter 180 degrees so that the (-) tilt arrow points toward the plate. The position of the locator bars will again be as shown in Figure 5a. Wait until the displayed reading stabilizes, or note the average if the reading fluctuates. Record this value (volts) in the X column of the log sheet. -
Page 14: Taking Readings
9.1.2 Taking Readings The metrology option log sheet in Appendix C is a master. Make copies for recording data during your survey. To survey the angle of a surface, place the tiltmeter in the desired location and read the output (volts). Write this number in the X column of the log sheet. -
Page 15: Making Contour Maps
Using procedures outlined in Sections ____________________________________________________________________________ For a detailed discussion of the tilt vector, ask for a copy of Jewell Instruments report no. A-93-1005, "Understanding Tilt Vectors and Processing Tiltmeter Data. -
Page 16: Maintenance And Troubleshooting
12.2 Determining Cause of Malfunctions Apart from the procedures described in this manual, your tiltmeter and readout module are not field-serviceable. If you encounter problems not described here, please contact Jewell Instruments LLC at telephone (603) 669-6400, or fax (603) 622-2690. A sales representative will assist you in determining the cause of any problem. - Page 17 If the continuity check reveals no broken connections, the problem may be internal to the tiltmeter. Contact the factory to arrange for a repair. Model 800P tiltmeters cannot be opened without special tools. OPENING THE TILTMETER VOIDS THE WARRANTY!
