Operation Manual
1. Test Tone – Select the test tone to be a sine wave if you want to
take voltage measurements using the internal test tones. Connect
the DM-RTA output so that the test tone tone will play in your
system.
2. Voltage display – This large meter displays the rms voltage of the
incoming sine wave.
Calibration
The voltage meter can be calibrated using the calibration menu avail-
able under the Tools menu. (Only the voltage meter has this option.)
This calibration routine allows you to enter a sine wave of known
voltage. The DM-RTA will measure this reference signal and adjust the
displayed reading to be exactly the voltage you entered.
