c. After adjustment, tighten the sensor jam nut to the specified torque
value (see table on page 30 ).

Specifications for the
Monitor Cable Use a commercially sold cable to connect the probe driver to the monitor. A
CVVS 3 core shielded cable (straight) is recommended, but if it is not available, a
3 line multiple core cable for light electrical instruments (individually shielded)
can be used. Use 0.75 mm
2
…1.25 mm
2
(18…16 AWG) cables.
ATTENTION: Always tighten the lock nut at the specified torque.
TIP The measurement precision described in the specifications will be satisfied
approximately five minutes after turning on the power.
Cable Name Note
CVVS 3 core shielded cable (straight) The CVVS 3 core shield is also recommended in the API Standard 670.
Recommendation: Copper tape shield (core wire; soft copper wire); (Normally,
silver plated braid)
Use conduit pipe (cable rack) for wiring.
3 line multiple core cable for light electrical instruments
(individually shielded) Recommendation: Outer shield is aluminum tape, copper tape shield
The multipair cable can contain a mixture of vibration signals and displacement
signals. However, vibration signals for a high amplitude vibration can affect other
vibration signals and displacement signals negatively; and these need to be
wired on a separate cable.
