Changing the exciting current value
To change the exciting current value, proceed as follows. However, the exciting current value is already
adjusted when the product is shipped from the factory. Do not change the exciting current value unless the
value is different from the one described on the detector nameplate. If you change this value to other value,
this may cause an error.
The following is an example to change the exciting current value from 0.1900A to 0.2150A.
