If you now associate 'myconfig' with a 2-wire temperature function,
'myconfig' stays on Channels 1 to 30, but because Channels 31 to 60 are no
longer paired, they are set back to a default DMM configuration setting of
'nofunction' because the unit has no way of knowing what configuration is
desired on those channels.
Likewise, changing a DMM configuration to pertain to a function not supported
by a channel will cause the channel to be set back to the 'nofunction'
setting. Continuing the example, if 'myconfig' is set to pertain to the DC
current function, then Channels 1 to 30, Slot 6, would be set to 'nofunction'
because these channels don't support the amp functionality.
Next, the following ICL commands are sent:
dmm.func = 'dccurrent'
dmm.configure.set('myconfig')
print(dmm.getconfig('slot6'))
The output will be 60 comma-delimited nofunctions, as follows:
nofunction,nofunction,nofunction,nofunction,nofunction,nofu
nction,nofunction,nofunction,nofunction,nofunction,nofun
ction,nofunction,nofunction,nofunction,nofunction,nofunc
tion,nofunction,nofunction,nofunction,nofunction,nofunct
ion,nofunction,nofunction,nofunction,nofunction,nofuncti
on,nofunction,nofunction,nofunction,nofunction,nofunctio
n,nofunction,nofunction,nofunction,nofunction,nofunction
,nofunction,nofunction,nofunction,nofunction,nofunction,
nofunction,nofunction,nofunction,nofunction,nofunction,n
ofunction,nofunction,nofunction,nofunction,nofunction,no
function,nofunction,nofunction,nofunction,nofunction,nof
unction,nofunction,nofunction,nofunction
As this example demonstrates, it is important to be careful when updating the
attributes associated with a DMM configuration. Changing settings within the
same function (for example, NPLC or range) will usually not change the DMM
configuration, but you should still be cautious. For example, you should be
careful changing a setting like transducer for temperature to indicate 2-pole or 4-
pole measurement operation.
