NSTALLATION NOTES
:
Do not open the gauge or loosen the cover screws.
Do not overtighten the fixing screws.
Do not use fixing screws that are too short or long. The correct screws [M5 by 16] are supplied
with the gauge head for mounting it to the HST3 height stand which has a thickness of 8mm. If a
stand of different thickness is used then the screw length supplied may not be suitable.
Do not place in a position close to a hot surface.
Do not allow the cable being measured to touch the gauge head.
If a large cable is being measured then ensure that it is supported so that the cable end does not
catch on the gauge.
Ensure that the cable alignment is perpendicular to the face of the gauge with the least error
practically possible, an angle error of one degree gives a measurement error of 0.013%, at two
degrees this becomes 0.05%.

Earth connection
Connector type: M5 bolt
An earth wire of at least 6mm
2
must be attached via a crimp on ring terminal to the dedicated
M5 earth bolt on the case of the gauge.
Do not rely on the mounting bolts to provide a reliable earth path.
If a height stand is used then it must also be earthed via its own dedicated earth wire.
All earth wires should be kept as short as practical.
Shielded Cables
Use shielded cable for all signal connections.
Ensure that all cable shields are correctly clamped and electrically connected to their
connectors and metal connector shells at both ends.
