Bytes Function
1 n Command byte Each set bit in DMS_CMD is acknowledged by a bit in
DMS_STAT.
– Bit 0: Activate Input Freeze à DMS_STAT bit 0: active
– Bit 1: Store adjustment à DMS_STAT bit 5: active
– Bit 2: Delete adjustment à DMS_STAT bit 5: active
– Bit 3: Set Tara à DMS_STAT bit 3: active
– Bit 4: Delete Tara à DMS_STAT bit 3: active
– Bit 5: reserved
– Bit 6: Set zero point à DMS_STAT bit 7: active
– Bit 7: Set reference point à DMS_STAT bit 7: active
n Input Freeze
– In the activated state no measurement values are passed to the digital filter.
– By a brief activation of Input Freeze pulses, e.g. caused by a filling procedure can
be prevented, which would override the filter unnecessarily.
– The status of Input Freeze can be determined at any time via bit 0 of DMS_STAT.
n Adjustment
– Store adjustment: Used to store the adjustment data when loaded with the refer-
ence weight.
– Delete adjustment: Used to delete the adjustment data.
– With both commands bit 5 of DMS_STAT is set. In case of error bit 4 is set.
n Tara
– Set Tara: The current value is taken as tara.
– Delete Tara: Tara is reset to 0.
– With both commands bit 3 of DMS_STAT is set.
n Zero balance respectively reference point
– Both commands are used for user adjustment and on both commands bit 7 of
DMS_STAT is set.
– Set zero balance: Used to set the balance to 0 when operated without load.
– Set reference point: Used to adjust the balance when it is loaded with a reference
weight.
