keeping the instrument.
-
In case a relay box is used to extend the cable, make sure of insulation, wiring, contamination, humidity
and so on.
-
Since this instrument is likely to be affected characteristically by static induction current from outside, the
grounding is very important for the prevention of factors that hinder the measurement with the
instrument. Even at the place where a perfect grounding is regarded as being established, induced
voltage or potential differences of direct currents or alternating currents may generate through the
electrostatic capacity between instrument and ground or instrument and power sources due to induced
currents from various power sources of a plant facility; consequently, take extra care for the grounding of
the instrument in order to eliminate measurement errors.
-
It should be noted that accurate indications may not be obtained in case the dedicated cable to connect
the instrument to the electrode is soaked with moisture or is contaminated when handling the wiring
connection of the electrode cable.
-
The use of a general-purpose cable or an extension with electric tape in the middle instead of an
instrument-only cable should be avoided; a relay box is recommended.

Quality assurance
(1) The instrument comes with one year guaranty from the date of purchase, and all costs and expenses for
after-services performed in connection with mechanical failures of the instrument during the guaranty
period are borne by the maker; except that the costs and expenses arising from causes attributable to
