Notes:
1.
± 10 arc seconds. This resolution is true only in the range of ± 5 ° from
vertical.
Beyond this, the resolution is diminished by the cosine of the angle from vertical.
2. Within
3 ° of vertical. This takes into account the accumulation of the error
inherent with each reading and normal placement errors in positioning the
probe inside the casing; also the effect of debris in the casing or casing
damage.
3.
The cable connector adds 150 mm to the length of the probe.
The wheel
diameter is 30mm.
4.
The probe is designed for use in all standard inclinometer casing up to a
maximum diameter of 89 mm (3.5 inches).
5.
The Inclinometer Probe is a highly sensitive device and should be treated with
great care at all times in order to maintain calibration. In particular, the probe
should be prevented from impacting the bottom of the casing with any force.
