Chapter 5 - Calibration

Chapter 5 provides the recommended calibration procedure for the HI1734-WS Weigh Scale Module. For the
module to work properly, it must be calibrated prior to operation, and it should be recalibrated periodically or
when not in use for extended periods of time. Be sure to follow all the procedures completely to insure that the
weights read by the module are accurate. Users and service personnel should be familiar with the procedures in
this chapter before installing or operating the Weigh Module.

Pre-Calibration Procedures

Verify that the load sensors have been properly installed.

Step 1. Determine if the load sensors have been properly installed. See your load sensor’s

installation manual for proper installation instructions.

Step 2. An arrow on some sensors and cells indicates the correct direction of the applied load, which

is facing down. If the arrow points in the wrong direction, reposition the load sensor so the
arrows are facing down.

Step 3. Check for Binding on the Load sensor, mount or other parts of the weighing system.

Load sensors must be mounted so that 100% of the
load (Vessel w/Contents) passes vertically through all
the sensors comprising the system.

Verify that nothing is binding the load sensors. This
means that nothing is draped  across the scale/vessel or
the load sensor,  such as a hose, electrical cord, tubes, or
other objects. Verify that nothing is in  contact with the
scale/vessel other than  service wires and piping that
have been  properly mounted with flexible  connections.
Flexible pipes are not to be  used in any other than the
horizontal plane and are not to be used to correct  pipe
alignment problems. Vertical or at  angles other than
horizontal will have a negative  effect on the scales
ability to repeat and provide accurate weight
readings.

WARNING -

BINDING ON A SCALE/VESSEL OR LOAD CELL DOES NOT ALLOW

THE LOAD SENSOR FREE VERTICAL MOVEMENT AND MAY PREVENT THE
INSTRUMENT FROM RETURNING TO THE ORIGINAL ZERO REFERENCE

ATTENTION –
