How to Use the Digital Multimeter
To utilize the built-in digital multimeter, press either the left or right
arrow keys from the main menu screen. The symbols for Voltage
DC, Ohms, and Voltage AC will appear. See screenshot below.
Connect the Pro50™ to the zone or item you wish to test. Press F1
for DC Voltage, F2 for resistance ohms, or F3 for AC Voltage. The
Pro50™ has auto-range capability, meaning that the expected
range is not required to be entered into the Pro50™.
How to Send Tone
From the home screen, press either the left or right arrow two times
to get to the send tone screen. See picture below.
Then press F2 to activate the built in tone generator for wire
identification. The three lines will blink, indicating that tone is being
sent. A Pro210F™ filter probe will be required to hear the tone at
the far end. When activating the tone, connect the red alligator clip
of the Pro50™ to a single conductor that the user wishes to identify.
Connect the black alligator clip to ground for best signal. Once
connected and activated, the user can identify the cable attached to
the Pro50™ by taking the Pro210F™ to the far end of the cable and
listening for the loudest tone coming from a particular cable or wire.
The loudest is generally the wire to be identified.
