used to select the instrument,
by entering the enabling code
displayed.
The buttons used are shown in the  gure. By pressing the
button,
each instrument displays its own remote control enabling code (parameter
c51). The numeric keypad is used to enter the enabling code of the
instrument in question. At the end of this operation, only the instrument
with the selected enabling code will be programmed from the remote
control, all the others will resume normal operation. Assigning di erent
enabling codes to the instruments, allows, in this phase, only the desired
instrument to be programmed using the remote control, without the
risk of interference. The instrument enabled for programming from the
remote control will display the reading and the message rCt. This status
is called Level 0. When having entered programming mode, pressing
for 5 seconds exits the programming of the remote control, saving
the modi cations; vice-versa, press
Esc
to exit the programming of the
remote control, without saving the modi cations.
