Note
- Note 1 : Without temperature compensation, 0.0-100.0 MΩ•cm(0-1000 kΩ•m) can be displayed.
- Note 2 : When the sensor cable, the transmission cable, or the contact input cable is extended by 30 m or more, the surge test under the EMC Directive for CE marking is not applied.
- Note 3 : An arrester (spark over voltage: 400 V) is implemented for transmission output, contact input, and communication. However, use a most suitable surge absorption element on the connection lines in accordance with the ambient environment, the situation of equipment installed, and the externally connected equipment.
