direct voltage output from the iLoad Analog, use the stabilized voltage at no load at any
new temperature as your new zero load voltage.

Sensor Noise:

Using the average of 5 - 10 readings will ensure smoothing of any noise in the output of
the sensor.

Direction of Loading:

For best results, please ensure that the force is applied in a direction normal to the top
surface of the sensor. Any angular force vector or moment may lead to inaccuracy. If
your configuration allows it, we recommend that you use a steel ball of 3/8”—3/4”
diameter placed directly on the hole in the center of the top dome for compression-only
iLoad sensors. The ball will help properly concentrate and direct the force to optimize
accuracy. If you are using the sensor in tension, ensure that you are minimizing any side
loads to the screw threads to which the load is applied. Do not insert a screw into the
hole at the top of the dome on a compression-only iLoad Sensor; this will affect the
accuracy of the device.

If you are using a sensor in both compression and tension, we recommend for best
accuracy that you tare the sensor when the direction of the applied force changes
direction. Ideally, this tare should be taken with a small (~1% capacity) pre-load in the
direction (compression or tension) of loading to be measured.

Mounting:

If used horizontally, the sensor may be placed on a flat hard surface. The three small legs
on the bottom will support the sensor correctly. If the location is not horizontal or if the
sensor needs to be secured to a fixed location, use three screws to mount the sensor.

Following the dimensions on the iLoad Series specification sheet, ensure that the
mounting holes are precisely located so that tightening the screws does not add any pre-
stress to the case of the sensor.

Over tightening of the mounting screws may also pre-stress the case and reduce accuracy.

Of course, if you are using the sensors with the TX-300 or TX-325 tension adapters, use
the screw threads provided to mount the sensor.

In all cases, ensure that there is no contact or force applied to the center disc on the base
of the sensor.

If you are building a scale with multiple sensors – place the weighing platform on top of
the sensors making sure that the top of the dome is in contact with the platform. Shim as
required to ensure contact.
