Note
- Note 1: The maximum load resistance is available within the range shown in the figure below, depending on power supply voltage:
Relation between power supply voltage and load resistance
- Note 2: The standard for effect on the reading by the electromagnetic field of the radiated radio frequency and by the conducted interference is within the measured pH value 0.1 pH.
- Note 3: 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 4: 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.
