trained, weighing equipment experts. We make certain that your weighing equipment is
ready for production in a cost effective and timely fashion, and that personnel are trained
for success.

b. Initial Calibration Documentation: The installation environment and application

requirements are unique for every industrial scale, so performance must be tested and
certified. Our calibration services and certificates document accuracy to ensure production
quality and provide a quality system record of performance.

c. Periodic Calibration Maintenance: A Calibration Service Agreement provides on-going

confidence in your weighing process and documentation of compliance. We offer a variety
of service plans that meet your needs and fit your budget.

d. GWP

®

Verification: A risk-based approach for managing weighing equipment allows for
control and improvement of the entire measuring process, which ensures reproducible
product quality and minimizes process costs. GWP (Good Weighing Practice), the science­based standard for efficient life-cycle management of weighing equipment, gives clear
answers about how to specify, calibrate and ensure accuracy of weighing equipment,
independent of make or brand.

ENTER key to make a selection from the device menu and sub-menus.

When in a data entry field, press the ENTER key to accept the numeric value
entered.

When the display is in weighing mode, briefly press the ENTER key to
execute the zero operation if the scale weight is within the Pushbutton zero
range specified in Setup+.

UP

Press the UP key to scroll within the device menu and sub-menus. The UP
key is also used for incrementing numerals in the numeric data entry field.

DOWN

Press the DOWN key to scroll within the device menu and sub-menus. The
DOWN key is also used for decrementing numerals in the numeric data
entry field.

LEFT

Press the LEFT key to navigate up one step on the device menu tree. The
LEFT key is also used to scroll to the numeral to the left in a data entry field.
With the left most numeric character highlighted, the next key press will
wrap around to the right most numeral.

Operation

Once focus is in a value field, repeated presses of the UP, DOWN or LEFT keys will
cycle back to the beginning, so if the LEFT key is pressed when focus is in the left­most position, focus returns to the right-most position. In the case of the UP and
DOWN keys, the numerical value will cycle through numerical values and the
decimal point as follows:

0 > 1 > 2 > 3 > 4 > 5 > 6 > 7 > 8 > 9 > . 0 > 1 > …

0 > . > 9 > 8 > 7 > 6 > 5 > 4 > 3 > 2 > 1 > . > …

After accepting the value by pressing ENTER and the focus has moved to the parameter
description, press the LEFT key to exit to the next higher level of the menu.

Pressing the LEFT multiple times will exit the device menu.

Figure 2-3 shows an example of how to access and modify the value of a parameter.
The currently selected item (in focus) is indicated by reverse video.

Operation

2.4.1. Information Recall

Once the Information Recall icon appears, press the ENTER key to recall
specific information about the transmitter. Figure 2-4 shows the elements of
the Information Recall menu in the sequence in which they occur. Note that
some items may not appear, depending on the configuration of the transmitter.

Operation

2.4.2. x10 Resolution

This function expands the weight display resolution by 10 so that a finer
weight increment can be seen. It can be enabled by pressing the ENTER key

when the transmitter’s device menu has been accessed and the

icon is displayed on screen:

Figure 2-5: x10 Indication

2.4.3. Comparators

The device supports a total of five comparators. One, two or all five
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, and can be written to the device or read from it by the PLC.

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.

If the operator is a single value, only one limit value can be set for the
comparator. Pressing the ENTER key again returns to the list of comparators.
If the operator is a range, then the Limit screen is followed by the High Limit
screen, from which the ENTER key exits back to the list of comparators. To
edit parameters other than limits, Comparator configuration must be accessed
in setup. Refer to the Numerical Data Entry section for the method used to
modify numerical values.

NOTICE

THE x10 DISPLAY RESOLUTION SETTING CANNOT BE CONFIGURED USING SETUP+.

The function is intended for diagnostic purposes only. The transmitter should not be used in the
x10 expanded mode for normal operation. The Data Ok bit is set to zero when in x10 display
mode to indicate that the ACT350 is not in normal operating mode. The PLC should continuously
monitor the Data OK bit in the ACT350 communication to determine the validity of data received
by the PLC.

30303895 | 001 | 09/2018 METTLER TOLEDO ACT350 Transmitter User's Guide 14

Operation

2.4.4. 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 ACT350 transmitter calibration menu enables entry of a GEO Codes
adjustment value, selection of linearity adjustment (none [default], three,
four or five 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.

 CalFree calibration – Once certain load cell criteria have been entered

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

30303895 | 001 | 09/2018 METTLER TOLEDO ACT350 Transmitter User's Guide 15

Operation

2.4.4.1. Setting Calibration

Access to the Calibration menu using the device's front panel is accomplished
by pressing the ENTER key when the icon is displayed on the device.
The Calibration menu also can be accessed using the PC-based Setup+

Configuration Tool.

Figure 2-6: Calibration Menu – Overview

2.4.4.2. Setting Geo Code

The Geo code, which sets the appropriate adjustment value for the current
geographical location, is selected here. Geo codes are numbered 0–31. See
Figure 2-6 for more information on the Geo code setting using the transmitter’s
front panel buttons, and refer to Appendix E, Geo Codes to find the appropriate
Geo Code for the installation location.
