SBTx
±nnn.nn 
Sets the begin-trigger level for starting the data acquisition. 
SBT  Denotes set begin-trigger. 
x  Denotes trigger source:  F = flow, P = pressure. 
±  Denotes positive or negative trigger:  + = positive, - = 
negative. 
nnn.nn  Set trigger level (‘001.00’ could denote 1.00 Std L/min, 
leading and trailing zeros must be included).  
The set trigger level stays in effect until cleared using the CBT 
command. The trigger level is also cleared when the flowmeter is 
turned off or the DEFAULT command is initiated. The SAVE 
command does not save this parameter 
After the command is processed, an acknowledge sequence of “OK” 
<CR> <LF> is sent. If the command generated an error instead of 
“OK” <CR> <LF> being sent, an error code of “ERRn” <CR> <LF> will 
be sent. See the end of this section for a list of possible error codes. 
Example 1)  SBTF+002.00  Sets a begin-trigger level at a flow of 2.00 
Std L/min with positive slope.
