R44: Forced calibration interval
This register contains the interval for the terminal's forced calibration. This interval is always a multiple
(default: 3
dec
) of the calibration interval (R40). The interval for forced calibration when the terminal leaves the
factory is therefore 3 x 180 s = 540 s. The forced calibration can be enabled through bit R32.4 [
}
47] in the
feature register.
If register R44 is set to 0 set, forced calibration is switched off completely.
R45: threshold for reference voltage test
This register contains the limit for the reference voltage test. The unit is 1 mV. If the reference voltage is
found to be below this limit, bit
R0.14 [
}
44] is set in the status word.
R46: threshold for correction factor
This register contains the limit value for the correction factor. A correction factor for the differential signal is
determined in the course of calibration. When measuring the internal reference, this results from the quotient
of the reference and differential signal. To represent it more clearly, the result is normalized to 10000
(U
Ref
/ U
Diff
x 10000), which means that 10000 corresponds to a factor of 1. In mapped calibration data, the
correction factor is output in R5 [
}
45] . If the difference between the correction factor and 10000 (10000 -
correction factor) is greater than this limit, bit R0.15 [
}
44] is set in the status word.
R47: calibration stabilization - number of stable measured values
Default: 50
R48: calibration stabilization - tolerance for measurement stability
Default: 5
R49: manual calibration weight
Default: 2000 grams

R32 to R63: freely allocatable SEEPROM memory
Registers R32 to R63 on register page 1 are freely available, non-volatile registers that can be used to store
2 x 32 words of user data. Because these values are stored in SEEPROM, they are retained when the
terminal is restarted.

R32 to R63: freely allocatable SEEPROM memory
Registers R32 to R63 on register page 2 are freely available, non-volatile registers that can be used to store
2 x 32 words of user data. Because these values are stored in SEEPROM, they are retained when the
terminal is restarted.
