Set mX+b units through the remote interface
You can set mX+b units through the remote interface with the command
dmm.math.mxb.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 (°), the micro symbol (µ), or the ohms
symbol
(Ω).
The ohm symbol (Ω), the micro symbol (µ), and the degree symbol (°) are not ASCII characters and
must be substituted with the ']', '[' and '\' characters. Valid characters are therefore:
•
A
to
Z
•
]
for ohms
•
[
for microvolts
•
\
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
When sending mxb units remotely, to embed a '\' into a string, precede the '\' with an additional '\'
(see the previous example code).
(on page 11-201) and
(on page 11-202) to set
the b and m factor for mX+b.
Once all settings are configured, set
(on page 11-198) to
dmm.ON
to enable math
operation.
For more detail, see
(on page 11-203).
