Setting mX+b units
The attribute for dmm.math.mxb.units must be one character enclosed in single or double
quotes. It can be any letter of the alphabet, the degrees symbol (°) or the ohms symbol (Ω).
To set mX=B units from the front panel:
NOTE
The following procedure sets MXBUNITS (MXB units), the other MATH menu options
(BFACTOR and MFACTOR) may also be changed by the b and m values.
1. Press the
CONFIG
key.
2. Press the
DMM
key.
3. Turn the 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 WHEEL to enter EDIT mode.
8. Scroll until the desired character is displayed, then press the
ENTER
key. The MATH MENU
will open.
9. From the MATH MENU, turn the wheel to highlight and select the "ENABLE" menu item.
10. Select ON and press the
ENTER
key.
11. Press the

key twice to return to the main display.
To set mX=B units from a remote interface:
The ohms symbol (Ω), the micro (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:
