Usage
value = dmm.dbreference
dmm.dbreference = value
value
The dB reference in volts (1e-7 to 1000)
Details
The dB reference setting applies only when dmm.func is set to "dcvolts" or "acvolts". If you
query this value for any other function, nil is returned.
An error is generated:
• If you send this command for any function other than "dcvolts" or "acvolts".
• If the value is out of range.
The dB reference setting is saved with the dmm.func function setting, so if you use another function,
then return to "dcvolts" or "acvolts", the dB reference setting you set previously are retained.
Example
dmm.func = "dcvolts"
dmm.dbreference = 5
Sets the dB reference to 5 volts for DC volts.
