recal_spd_pm

Purpose:

Recalibrate the speed and period measurement tables.

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_teeth

Run the ‘bld_tables’ process to activate a table.

Notes:

The actual calibration table filename will have the .tbl extender and will be found in the /cell/tables/ directory. The ‘table_name’ argument does not include the .tbl extender.
