Cal Function
The baseline and sensitivity of the chart recorder can be set up using the Cal function. This generates a zero
velocity baseline and a sequence of bi-directional pulses as shown below:
Gain Control
To cope with the wide variety of signals detectable to the Doppler, the gain control lets you optimise the bar-
graph display and increase the height of the waveforms.
Press the Mode/Gain button repeatedly, to set gain to x1, x2, x4, x8.
Connection to Software (MD2 only)
The MD2 can be connected to the Reporter Software Package, via the RS232 interface. Dopplex Reporter
software package is available as an accessory. Communicating is then initiated by using the Start/Stop button.
