To set mX+B units from the front panel:
NOTE The following procedure sets MXBUNITS. You can change the other
MATH menu options (BFACTOR and MFACTOR) by changing the b
and m values.
1. Press the CONFIG key.
2. Press the DMM key.
3. Turn the navigation wheel to highlight the MATH menu item.
4. With MATH highlighted, press the ENTER key. The MATH MENU opens.
5. Select the MXBUNITS menu item.
6. With MXBUNITS highlighted, press the ENTER key.
7. Press the navigation wheel to enter EDIT mode.
8. Scroll until the desired character is displayed, and then press the ENTER
key. The MATH MENU will open.
9. From the MATH MENU, turn the navigation wheel to highlight and select the
ENABLE menu item.
10. Select ON and press the ENTER key.
11. Press the EXIT key twice to return to the main display.
To set mX=B units from a remote interface:
The ohms symbol (Ω), the micro symbol (µ), and the degrees symbol (°) are not
ASCII characters and must be substituted with the ']', '[' and '\' characters. Valid
characters are therefore from A to Z, ']' for ohms, '[' for microvolts, and '\' for
degrees.
To use the ohms symbol (Ω) as units designator:
value = ']'
dmm.math.mxb.units = value
To use the micro symbol (µ) as units designator:
value = '['
dmm.math.mxb.units = value
To use the degrees symbol (°) as units designator:
value = '\\'
dmm.math.mxb.units = value
NOTE When sending mxb units remotely, to embed a '\' into a string, precede
the '\' with an additional '\' (see the previous paragraph).
