value
For DC volts and AC volts, select from the following units:
▪
dmm.UNITS_VOLTS
or
0
▪
dmm.UNITS_DECIBELS
or
1
For temperature, select from the following units:
▪
dmm.UNITS_CELSIUS
or

Details
This attribute is only valid when
dmm.func
is set to
"dcvolts"
,
"acvolts"
, or
"temperature"
.
All other functions generate an error and return nil when queried.
The units value is saved with the
dmm.func
function setting, so if you use another function, then
return to
"dcvolts"
,
"acvolts"
, or
"temperature"
, the units setting you set previously is
retained.
Errors are generated if the parameter value does not make sense for the selected function.
Example
dmm.func = "temperature"
dmm.units = dmm.UNITS_FAHRENHEIT
Sets units for temperature measurements to
Fahrenheit (°F).
