adapter must be used. When headphones are connected, the internal
speaker is disabled.
The MONITOR Knob controls the amplitude of the headphones or the
internal monitor speaker.
Normally the speaker or headphones will monitor the input signal, so

cable connection inside the instrument which allows this to be
changed so that the monitor follows the measured signal, after being
processed for the reading. To make this change, see Appendix C.
