Cable errors

Usually external reference capacitors can be connected to the interface allowing an ultra-stable reference to be used if one is available. This also provides best matching of cable errors since the same type of connection cables can be used on the sample and on the reference. The reference technique is especially usefiil when using external amplifiers for high voltage tests, though the reference capacitor must be chosen with care to withstand the applied voltage level. 

Remote I/O sub systems reduce cabling and reduce risk of cabling errors. 

Combined Effect of Capacitance and Attenuation. When capacitance is high, the signal never reaches the 1 state before it starts declining to 0 again. This yields a signal in which the 1 and 0 states are nearly indistinguishable by the receiver and an error results. Since capacitance and attenuation are always present in telephone cables, for error-free transmissions the communications wire must have the lowest capacitance and attenuation possible. 

The switching-off method for 7/ -free potential measurement is, according to the data in Fig. 3-5, subject to error with lead-sheathed cables. For a rough survey, measurements of potential can be used to set up and control the cathodic protection. This means that no information can be gathered on the complete corrosion protection, but only on the protection current entry and the elimination of cell activity from contacts with foreign cathodic structures. The reverse switching method in Section 3.3.1 can be used to obtain an accurate potential measurement. Rest and protection potentials for buried cables are listed in Table 13-1 as an appendix to Section 2.4. The protection potential region lies within U[[Pg.326]

Fox s perfectionism is illustrated by an anecdote At a meeting held at ICI (his previous employer), Fox presented his final design for a two-mile cable transporter. Suddenly he clapped his hand to his head and exclaimed How could I have made such an error Then he explained to his alarmed colleagues I forgot to allow for the curvature of the Earth . 

In order to reduce sampling errors, during the preliminary tests, in the sampling process, the slurry was sampled with a device, consisting of a rigid tube, 3cm in diameter and 3m in height, into which a plasticcoated steel cable was placed, to which a rubber sphere, 6cm in diameter was anchored. The sphere closes the lower end of the tube itself. 

NOTE Several possibilities for the drawn circle not including the origin of the polar chart are operator error during balancing, a faulty balancing machine pickup or cable, or the balancing machine is not sensitive enough. 

The power generation of SC-SOFC is dependent on the resistance of the materials. The electrolyte itself, the chemical reactions, and the overpotential contribute to the impedance, which is measured with a load of half the short circuit current applied to the cell. Figure 3 shows the impedance spectra of a particular cell, fitted to an equivalent resistor/capacitor (RC) circuit. Usually, R1 is considered to be the electrolyte resistance with R2 and R3 as the overpotential of the electrodes. The inductance of the cables and the relaxation frequency of R2 and C2 tended to introduce error into the measurement of Rl. Therefore, R1 is usually measured together with R2 as R1 + R2 [31], Some cells may be significantly affected by the electrolyte resistance, which depends on thickness. 

Though the measurement uncertainty of each device has been checked, and care was taken to minimize measurement errors, inaccuracies of measurement cannot be ruled out. The higher peak loss factor for the resonant apparatus for example may be due to vibrational energy propagating into the dangling accelerometer cable.

Apparemly, (he proximity of the cabinet door provided the path lor interaction between the two circuits, resulting in recurring computer error. The exact mechanism involved is not known, but it is similar in some respects to imiltiple-groimded circuits that exhibit interactions because of the grounds. Such grounds can accidentally l e applied to sensitive circuitry through the third wire in a three-wire power cord to test instruments or through the shield of a shielded cable, to name just two. The point to note is that extreme care should be...

In addition to the cable position, you must also set the drive type and size of the floppy drive in the CMOS setup. This is done so that the computer will know what drives are attached. If this information is wrong, most computers will detect that the wrong drive type is selected and an error will occur during bootup. 

Floppy disk error. Either the floppy adapter or the floppy drive failed. Check to see that the floppy cable isn t on upside down and that the power to the floppy drive(s) is hooked up correctly. 

Reseat chips and cables. You can solve some of the strangest problems (random hang-ups or errors) by opening the case and pressing down on each socketed chip. This remedies the chip creep problem mentioned earlier in the book. In addition, you should also reseat any cables to make sure that they are making good contact.
