RANGE? QUERY
Returns the selected range.
Syntax:
Response:
0 = RANGE_OFF
1 = R20mOHM
2 = R200mOHM
3 = R2_OHM
4 = R20_OHM
5 = R200_OHM
6 = R2K_OHM
7 = R20K_OHM
A = RANGE_AUTO
RDNG? QUERY
Responds with reading from the device in engineering notation. Query function also uses
an immediate update of the conversion so repeated query requests gets the most
accurate data.
Syntax:
Example:
Response:
Power-on default = 0.000e+0
CAUTION: Will not work if the transmit interrupt happens to be busy with a display update
and the following occurs:
