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.
