7.6 Measuring by Remote Control
After switching on the counter is in the starting position, i. e. the function “CHK”, the
measuring time 100 ms and the divider ratio 1:1 are set. The operation is done at the unit.
The unit is switched to remote control and afterwards is controlled by the respective
commands. Thereby, it should be noted that single commands or group of commands have to
be separated by “
;
” (ASCII: 3BH) and ended by the end character LF (ASCII:
∅
AH).
Certain commands can contain parameters which are separated by a colon “
:
” (ASCII: 3AH)
from the command.
A simple example would be: “*REM”,
∅
AH
“FREQA;GATE:1MS;ATT:10”,
∅
AH
“*TRG?”,
∅
AH.
