RANGE QUERY
Returns the selected range.
Syntax:
RANGE?
Response:
Range number = 0 - 7
0 = RANGE_OFF (SAFE MODE)
1 = R20mOHM
2 = R200mOHM
3 = R2_OHM
4 = R20_OHM
5 = R200_OHM
6 = R2K_OHM
7 = R20K_OHM
A = RANGE_AUTO
Power-on default = 7
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:
RDNG?
Example:
RDNG?<crlf>
2.4321e+1<crlf> (on 20.000 Ohm ranges)
Response:
<value in reduced engineering notation<crlf>>
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:
Remote ->RANGE 6 <2k Ohm)
System ->Places "REM^" in TX buffer (Tiny Display)
System ->Change to R6
System ->Places "2k^" in TX buffer (Tiny Display)
System ->Formats Display String "1.6543k^"
Remote ->READING?
System ->Places in TX buffer to VFD 'D' characters
Remote ->RANGE 4
System ->Change to R4
System ->Executes READING? query, uses Range=4 and last displayed value
System ->Places in TX buffer, next 'R' characters
