Ratings
Note: 1.
The 61F may not operate at resistance settings close to zero. Adjust the sensitivity to match actual usage conditions.
2.
The figure for wiring distance above is for when 600-V 3-core cabtyre cable with a cross-sectional area of 0.75 mm

Characteristics
Note:
The dielectric strength is measured between power terminals
and electrode terminals, power terminals and output terminals,
and between electrode terminals and output terminals.
