Using a Digital Multimeter (DMM) Probe for Testing 4 Pin Cable
A digital multimeter (DMM) is a test tool that is used to measure two or more electrical values such as voltage (volts),
current (amps), and resistance (ohms). It is a standard diagnostic tool for technicians in the electrical industry.
Improper use of the DMM probe may damage the pins causing an intermittent connection. Be sure the probe only
makes contact with the outside edge of the female connector. If the probe is inserted into the connector it may distort
the pin and ruin the connection.
