The selection, arrangement and presentation of all materials on this document and the overall design of this document is the exclusive
property of Sapcon Instruments Pvt. Ltd.

The images shown in this manual may differ from the actual instrument / housing in terms of dimensions, color and design. Please refer
to GA drawings for dimensional details.

Values (of performance) described in this manual were obtained under ideal testing conditions. Hence, they may differ under industrial
environment and settings.

General Instructions

Instrument shouldn’t block the material filling inlet.

Secure the cover of housing tightly. Tighten the cable glands. For side mounting, the cable glands should point downwards.

For side mounting, provide a baffle to prevent the material from falling on the probe.

When handling forks, do not lift them using their tines. While using them with solids, ensure that material size is less than 10mm.

Deforming the shape of the tines may interfere with the fork’s operating frequency.

Make all electrical connections as instructed in the manual. Don’t power on the device before verifying the connections.
