table 13: GK-604D Specifications

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 30 mm.

4 The probe is designed for use in all standard inclinometer casing up to a maximum diameter of 89 mm (3.5").

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.

table 15: Analog Probe System Specifications

NOTES:

1 The probe outputs ±4 volts at an inclination of ±30° to the vertical. These parameters are referred to as full scale. Operation beyond this inclination is not possible with a standard MEMS probe.

2 The resolution shown in Table 8 above is only true in the range of ± 5° from the vertical. Beyond this, the resolution is reduced by a factor equal to 1 / cosine of the angle from the vertical. For instance, the resolution at 0 degrees from vertical is 10.3 arc seconds and the resolution at 15 degrees from the vertical is 10.3 x 1 / 0.966 = 10.7 arc seconds. The figures given assume that the readout box can detect a change of output of 0.0005 VDC.

3 The figure shown applies to the use of a single probe used repeatedly over a short space of time in a single borehole.

4 In practice, system accuracy is controlled mainly by the precision with which the inclinometer can be positioned at exactly the same depth in the casing from survey to survey. Factors such as debris in the casing or casing damage also have an effect. The stated accuracy assumes that the surveys are conducted over a period of time, in a proper manner, and that the casing is within five degrees of vertical. Accuracy is improved by allowing the probe to reach equilibrium at each depth before taking a reading.

5 The probe is designed for use in all standard inclinometer casing up to a maximum diameter of 89 mm (3.5").

6 The wheel diameter is 30 mm. The cable connector adds 150 mm to the length of the probe.
