7.7.1 Defining the scale type ( SCALE –> Scale Build –> Scale Type )
The following scale types are available
"Single Range"
"2 Multi Interval"
"2 Multi Range"
"3 Multi Interval"
"3 Multi Range"
7.7.2 Specifying the base unit ( SCALE –> Scale Build –> Base Unit )
The base unit can be specified in this menu. The base unit is used for determining the capacity of the weighing system and the
resolution and has nothing to do with the weighing unit used for day-to-day operation (this is specified separately, see User
Manual). The following units are available: gram (g), kilogram (kg), metric ton (t), pound (lb) and ounce (oz).
Note: Only "g", "kg" and "t" are available on weighing systems that are suitable for certification to OIML. Only "kg" and "lb" are
available on weighing systems that are suitable for certification to NTEP.
7.7.3 Choosing the verification interval ( SCALE –> Scale Build –> Verification Interval )
This setting is only relevant for certifiable weighing systems (Chapter 7.3). The following verification intervals are available:
"e = d" and "e = 10d".
Note: If the verification interval is set to "e = 10d", the last digit of the weighing result is displayed in brackets (known as
calibration brackets). These indicate that the last digit is not taken into account for calibration tolerance. If the verification
interval is set to "e = d", the weighing result is displayed without brackets.
7.7.4 Specifying the capacity of the weighing system ( SCALE –> Scale Build –> Scale Capacity )
The capacity of the weighing system must be specified when building a new scale using a terminal. Furthermore, if the
analog PCB is replaced, it is necessary to specify the capacity, because the EEPROM on the PCB is set to a default value at the
factory. On compact scales FTx the capacity is shown on the plate above the display and must be set to this value. It is also
necessary to set the capacity if a load cell of a different capacity is installed. In this case the capacity must be set in
accordance with the load cell used (see specifications in Chapter 8).
Entering the scale capacity (in the previously selected basic unit)
The capacity can be entered with the numerical keypad for KMT-TM terminals (ITT). Press the
FTx and KMB-/KMS-TM terminals (ITB/ITS) . The first digit starts flashing and can now be changed with the
keys. Confirm new digit with the
applies for all following digits (seven total).
If it is a multi-interval scale or multi-range scale (see Chapter 7.7.1), this menu block can be accessed separately for
each weighing range ("Scale CAP. 1" to "Scale CAP. 3", depending on the number of weighing ranges). The additional
blocks for capacity are displayed after the "Resolution" block. The upper capacity limit must be entered for each weighing
range.
Example for a 30 kg dual-range scale: "SCL.CAP 1" = 15 kg, "SCL.CAP 2" = 30 kg. In this example switching from the fine
range to the coarse range occurs at 15 kg.
