Appendix 4 Countermeasures Against Incorporation of External Noise

The unit is designed to be resistant to errors caused by interference from the test cables or the power supply
line. However, if the level of the interference is particularly large, this can cause measurement errors or faulty
operation.
Refer to the examples given below for examples of countermeasures which can be taken against interference
which has caused faulty operation etc.
You can use the following countermeasures to reduce the effect of noise being incorporated from the power
line.
The unit is structured so that the ground wire of the power cable can be used as protective grounding for the
unit. Protective grounding plays an important role in not only the prevention of electrical accidents but also the
use of an internal filter to eliminate the incorporation of noise from the power line. Use the supplied power
cord.
Connect a commercial plug-in noise filter to the power outlet and then connect the unit to the output of the
noise filter in order to suppress the incorporation of noise from the power line.
Plug-in noise filters are commercially available from various specialist manufacturers.
