NPR <npr1p> <npr1n> [<npr2p> <npr2n>]
Where:
<npr1p> = the maximum nominal pressure
<npr1n> = the minimum nominal pressure
If the optional <npr2p> <npr2n> are entered, the DSA will identify as a dual range unit (lowest
range as 1 and highest range as 2). The variables will then be identified as:
<npr1p> = the maximum nominal pressure for channels 1 - 8
<npr1n> = the minimum nominal pressure for channels 1 - 8
<npr2p> = the maximum nominal pressure for channels 9 - 16
<npr2n> = the minimum nominal pressure for channels 9 - 16
NPR <npr1p> <npr1n> [<npr2p> <npr2n>]

15 -15
// set the NPR for a single range 100PSI unit
NPR 100 -15
>
// Retrieve the current NPR
NPR
NPR 5 -5
>
// set the NPR for a dual range 15/50PSI unit
NPR 15 -15 50 -15

This variable will not change the measurable range of the module, only the valid data bounds.
Invalid pressure data will be shown as 9999 errors in the channel data.
XITE
Get/Set
Determines the polarity of the excitation voltages applied to the sensors, or retrieves the current
setting.
XITE <value>
Where <value>:
0 = negative
1 = positive
XITE <value>
- and/or -
Prompt when ready to accept a new command.
