value
The range for the function selected by
dmm.func
Details
Set this value to the expected measurement value and the instrument will select the range
appropriate to measure that value. Setting the range with this attribute will automatically disable the
autorange setting (
dmm.autorange
command).
The instrument selects the range to best match the expected measure value for the functions, as
shown below.
Ranges and defaults
If dmm.func is…
The range is…
The default is…
"dcvolts"
0 to 303
303
"acvolts"
0 to 303
10
"dccurrent"
0 to 3.1
3.1
"accurrent"
0 to 3.1
3.1
"twowireohms"
0 to 120e6
1000
"fourwireohms"
0 to 120e6
1000
"commonsideohms"
0 to 120e6
1000
The range setting is saved with the
dmm.func
function setting, so if you use another function, then
return to the previous function, the range settings you set previously are retained.
If you query the range when the selected function does not have a range associated with it,
nil
is
returned.
An error is generated if:
•
The
dmm.range
is received when
dmm.func
is
"temperature"
,
"frequency"
,
"period"
,
"continuity"
, or
"nofunction"
.
•
If
value
does not make sense for selected function.
Example
dmm.func = "dcvolts"
dmm.range = 5
dmm.func = "twowireohms"
dmm.range = 35000
print(dmm.range)
Set the range for DC volts to 10. Select a
range on 2-wire ohms suitable for measuring
35000. View the selected range.
Output:
1.00005
