een sleeve and tip or ring
Message: 4.
Subject: Value of that resistor in ohms
For those without a suitable resistor to hand measurements 3 and 4 are
not essential but will be useful, particularly in determining if the
device uses a constant current supply.
Please do not undertake if you have any concerns for your or your
equipment's safety.
