strength and electrical properties. Contact
additional cable splicing instructions.
Cables may be terminated by stripping and tinning the individual conductors and
then connecting them to the patch cord of a readout box. Alternatively, a
connector may be used which will plug directly into the readout box or to a
receptacle on a special patch cord.
2.4 ELECTRICAL NOISE
Care should be exercised when installing instrument cables to keep them as far
away as possible from sources of electrical interference such as power lines,
generators, motors, transformers, arc welders, etc. Cables should never be
buried or run with AC power lines. The instrument cables will pick up the 50 or
60 Hz (or other frequency) noise from the power cable and this will likely cause a
problem obtaining a stable reading. Contact the factory concerning filtering
options available for use with the
difficulties arise.
2.5 INITIAL READINGS
Initial readings must be taken and carefully recorded along with the
barometric pressure and temperature at the time of installation. Take the initial
readings while the cell is in position, prior to covering it with fill and pouring the
concrete. Again, it is imperative that initial readings at zero load are
taken!
