®
4’s measurement storage area
0 ≤
position
≤ 32767
Integration Pascal:
procedure measurement_status(var busy: wordbool; var position: word);
C:
void measurement_status(unsigned short *busy, unsigned short
*position);
Basic:
sub measurement_status (busy As Integer, position As Integer)
Comments • The set_trigger command will always cause exactly 32768 values per measurement
channel to be measured and stored onto the RTC
