The unit is designed not to malfunction as a result of noise incorporated from
the probes, fixture, and power line. However, extremely large levels of noise
may still cause measurement errors and malfunctions.
Refer to the following examples of countermeasures against noise when the
unit malfunctions, etc
You can use the following countermeasures to reduce the effect of noise
being incorporated from the power line.
Grounding Using a Protective Ground Wire
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.
Attaching a Noise Filter to the Power Line
Connect a commercial plug-in noise filter to the power outlet and then con-
nect the unit to the output of the noise filter in order to suppress the incorpo-
ration of noise from the power line.
Plug-in noise filters are commercially available from various specialist manu-
facturers.
