INSERT
Set
Inserts one EU pressure to ADC pressure counts entry into the points conversion table, per chan-
nel and temperature range. These points are created during a full temperature calibration, and
should not be modified manually. These terms are used to create a polynomial fit coefficient using
the CONVERT command and are not used for EU conversions.
INSERT <raw temp> <channel> <pressure> <adc counts>
Where:
<raw temp> is the raw A/D counts that represent the temperature of the module
<channel> is the channel number from 1 to 16
<pressure> is the pressure in PSI (real value)
<adc counts> is the A/D counts at the specified pressure, as a signed integer from −8,388,608
to 8,388,607
Prompt when ready to accept a new command.
// Insert a master point for channel 1 at 30°C (raw counts read 1234422). The applied pressure is
11.9998 psi, the measured counts are 2416376
INSERT 1234422 1 11.9998 2416376

This command can modify or change the coefficient table which may result in inaccurate or unus-
able data. This command should not be used in the field.
CONVERT
Function
Retrieves the current INSERT settings and uses these points to create the least-squares conversion
values (K) along with the error correction values (A, B, C, D).
CONVERT CAL [<num temps>]
Where <num temps> is the number of temperatures in the insert list.
Prompt when ready to accept a new command.
// after inserts have been loaded into RAM, convert these points into the EU conversion terms
CONVERT CAL
>
This command can modify or change the coefficient table which may result in inaccurate or
unusable data. This command should not be used in the field unless instructed by a Scanivalve
representative.
