recal_spd_pm
Purpose:
-
Recalibrate the speed and period measurement tables based on the specified number of flywheel teeth.
Enter:
-
recal_spd_pm <period_tbl_name> <speed_tbl_name> <num_teeth>
Where:
-
period_tbl_name
Specify the period measurement calibration table name.
speed_tbl_name
Specify the speed calibration table name.
num_teeth
Specify the number of flywheel teeth to modify the calibration tables.
Example:
-
recal_spd_pm RPM_pm SPEED 159
The above computes the second coefficient of the HYPERBOLIC curve for the period measurement table by using the following calculation:coef_2 = (1000000*60*16)/num_teeth
The 2 point INTERP SPEED table is modified as follows:
eng_units_2 = raw_value_2 * 60 / num_teethRun the ‘bld_tables’ process to activate a table.
Notes:
-
The actual calibration table filename will have the .tbl extension and will be found in the /cell/tables/ directory. The table name argument does not include the .tbl extension.
