Comparators
The device supports a total of three comparators. One, two or all three
comparators may be used. The limit of each comparator may be modified by
accessing the Comparator menu in the setup menu. Comparator values are
limited to 7 digits.
2.4.3.1. Setting Comparators
Access the Comparator menu by pressing the ENTER key when the
transmitter’s device menu is visible and the icon is displayed on the
device.
The ACT100 only supports a logical comparison of “>=”, greater than or equal
to, for each comparator. For example, if the limit is set to “24.00” kg, the
output configured to use this comparator will be set to true only if the live
weight is greater than or equal to 24.00 kg. Please note that inputs and
outputs can be configured using the webserver.
The operator of range and other comparisons are NOT supported by the
ACT100.

Calibration
Calibration is the process of adjusting the display of the transmitter so that
when the scale is empty, the display shows zero gross weight. With a
specific amount of weight on the scale, it also shows an accurate weight
value.
The ACT100 transmitter calibration menu enables entry of an adjustment
value, selection of linearity adjustment (
point), traditional zero calibration and three different types of span
calibration:
•
Traditional span calibration – This uses test weights.
•
Step adjust calibration - Using a build-up or substitution method of
calibration, this method is used for large vessels where only a portion of
the required test weights can be placed on the scale.
[default], three, four or five
none
•

manually, the transmitter will automatically calculate the span; no test
weights are required.

30303895 | 00 | 08/2019
Figure 2-7: Zero Calibration
If the transmitter detects scale motion during the calibration process, it will
retry the start of calibration several times and then proceed, displaying a
motion indication. In this case, when calibration is complete, the transmitter
will present two options – accept or reject the value.
METTLER TOLEDO
ACT350 Transmitter User's Guide 16
Operation
NOTICE
Figure 2-8: Zero Calibration with Motion
Blanking of the display is used to indicate an under-zero condition when the
weight on the scale falls below the current zero reference. Set the under zero
blanking for the number of divisions (d) that the transmitter is permitted to
go under zero before blanking.
A setting value of 0-98 blanks the display at the specified number of divisions below gross
zero. A value of 99 makes the transmitter blanks at 50% of the capacity value in the negative
direction.
2.4.4.5. Span Calibration
The scale’s span calibration can be determined either with or without a
linearity adjustment. With linearity disabled, a single reference point is used
to calibrate the scale. This is the normal method of span calibration. With
linearity enabled, the transmitter is configured with up to three-point linearity
– low, mid and high.
The low point is set during zero calibration, and the mid and high points are
set during this procedure.

Operation
Figure 2-9: Span Calibration
If linearity is enabled, additional mid-range weight reference points are added
to the adjustment procedure. Linearity can be enabled or disabled in the
Calibration branch of the device menu. Refer to ACT100 Device Main Menu
section for the method used to modify numerical values.
2.4.4.6. Step Adjust
Step adjustment is an iterative process in which a build-up or material
substitution method of calibration is used to calibrate the span. Each step
calibrates a portion of the full span.
This method is typically used with large vessels where only a portion of the
required calibration test weights can be placed on the scale at one time. Figure
2-10 shows the logic of the procedure using a simple, two-step example.
When sufficient steps have been calibrated, pressing the LEFT button returns
the view to the calibration menu.
