Manual Verification for “4.1.5 Device Input Capacitance”
The capacitance parameters Cin & Cdiff measured by MxPLT includes the capacitance of the harness.
Use a harness less than one meter LONG to measure actual ECU capacitance values.
If the harness is more than one meter long, compensate for the harness capacitance in MxPLT measurements. See the images below:
With ECU
Without ECU
Actual Capacitance = With ECU - Without ECU
Cin = 132-36.1 = 95.9pf
Cdiff = 161-54.2 = 106.8pf as per above sample images.
