Usage
value = dmm.measure.detectorbandwidth
dmm.measure.detectorbandwidth = value
value
The bandwidth that is closest to the line frequency:
• 3 Hz: dmm.DETECTBW_3HZ
• 30 Hz: dmm.DETECTBW_30HZ
• 300 Hz:
dmm.DETECTBW_300HZ

Details
You can set the detector bandwidth to improve measurement accuracy. Select the bandwidth that
contains the lowest frequency component of the input signal. For example, if the lowest frequency
component of your input signal is 40 Hz, use a bandwidth setting of 30 Hz.
If the bandwidth is set to 3 Hz or 30 Hz, the autozero feature is always enabled and the integration
rate is fixed.
Example
dmm.measure.func = dmm.FUNC_AC_CURRENT
dmm.measure.detectorbandwidth =
dmm.DETECTBW_3HZ
Set the measure function to AC current.
Set the bandwidth to 3 Hz.
