How to get the HM8118 to provide the Q factor and other results via remote control

Answer

The HM8118 will display two measurements at the same time
these values are provided though remote commands as well

Please select the right function

PMOD(?) {i}
Use the PMOD command and the parameter to select the
measurement function:
i=0 : AUTO
i=1 : L-Q
i=2 : L-R
i=3 : C-D
i=4 : C-R
i=5 : R-Q
i=6 : Z-Θ
i=7 : Y+Θ
i=8 : R+X
i=9 : G+B
i=10 : N+Θ
i=11 : M
The PMOD? query queries the selected measurement function.

for example the R-Q function can be selected by
Write Operation (PMOD\s5\r)
It can be verified
Write Operation (PMOD?\r)
5\r

and with the command
XALL?

1.605101E-01,2.072357E-01,99\r
(the second value is the Q value since it is displayed)
