Only use cleaning agents that are compatible with
the materials to be cleaned. In addition, do not use
coarse materials such as steel wool for cleaning,
as they will damage the surface.
Rinse the conductivity cell thoroughly with distilled
water before installation.

Troubleshooting
1. If no signal appears at the display unit, check
the electrical connections. Another possible
cause of this problem is that the conductivity
cell is not in contact with the medium.
2. If no temperature signal is present, the tempera-
ture sensor may not be connected properly or
the device may not support NTC temperature
sensor (for InPro 7100 i) or Pt1000 temperature
sensor (for InPro 7100).
3. If the measuring signal is incorrect or instable,
the cause may be that the conductivity cell is
contaminated or fitted too close to the pipe (the
distance between the pipe and the end of the
conductivity cell should be 30 mm).
