* Programming the relative reference
The relative reference extension characters (Y...) are: D0, D1, D2, D3, D4 + G/S +CR
Each character D0 to D4 can be one of the values 30H to 39H.
D0 is the low order of the reference, and D4 is the high order.
The G/S character contains the range number (see ****), and the reference sign (add 8
in hexadecimal to the range number when the sign is negative).

** Programming the ohm reference in dB and in resistive power
The extension characters (Y...) of the ohm reference are: D0, D1, D2, D3 + CR
Each character D0 to D3 can be one of the values 30H to 39H. Therefore the ohm
reference may be programmed from 1 ohm to 9999 ohms.

*** Programming the rate of timer data
The 6 timer programming extension characters (Y...) are S0, S1, M0, M1, H1CR
They represent Hours (0 to 9), Minutes (00 to 59) and Seconds (00 to 59).
Each character may be equal to 30H to 39H.
