FNB38 uses the voltage drop method to measure the internal resistance of the cable. It needs to
be used with a constant current load.
Instructions
(1) << >>key
(2) Short press: page turning;
(3) OK key
Short press: Record the reference value. Long press: switch display curve.
Measurement steps
(1) Connection method: c FNB38 + constant current load (current adjusted to
about 1A), record the reference value.
(2) Connection method: c cable + FNB38 + constant current load (current adjusted
to about 1A), the system automatically calculates the cable internal resistance.

7.1 Fast charge protocol detection
After selecting Protocol detection protocol, short press OK to enter the state of automatic
detection of fast charging protocol.
After the test is completed, short press OK to exit the test interface.
Explanation
：
PD protocol detection, because some PD chargers will only send a complete PDO
after requesting the first voltage, and one-click detection will not make a voltage request, so the
