The continuous data stream rate is 100Hz at 9600 Baud and 250Hz at 115200 Baud

The continuous data stream rate is 100Hz at 9600 Baud and 250Hz at 115200 Baud

Please note that the continuous data stream only starts when approximately 2% of the rated capacity of the gauge
is reached.

Holding down the

TXD 

key whilst turning on the gauge will toggle between baud rates of 9600 and 115200. If the

baud rate is being toggled, when powered up the gauge will display either 9600 or 115.2 between displaying the
software version number and the loadcell capacity. The baud rate setting will be stored in memory and
remembered when the gauge is turned off.

 

Removing the minus sign during data transmission

Holding down the

MAX 

key while turning the gauge on will enable or disable sending a minus sign with RS232

transmission. If the ‘transmit sign’ function is enabled then ‘2’ is displayed in the top row of the display (See Fig.
7). This setting is stored in the memory and is remembered when the gauge is powered down.

To conserve battery power the gauge constantly keeps a record of time elapsed since the last key press. If 
this function is not disabled and the low battery symbol is not showing, the gauge will power down after
