7.3 Setting A/D Integration Time (Pen model)
The purpose of the following setting is to specify which A/D integration time will be used. Depending on the power supply, the integration time will affect the ability of noise rejection and therefore the recording.
If the power supply of the recorder and of the measuring object are the same, the effect of noise will be automatically minimized and the (initial) value of AUTO is the recommended one.
If the power supplies are different, you should select from 50Hz or 60Hz integration time. The choice depends on the power supply of the instrument with the highest noise level.
There are three possibilities:
•AUTO: integration time depends on the power supply of the recorder.
•50Hz
•60Hz.
The initial value is ‘AUTO’.
