*1. Use 61F-UHS for detecting water leakage with high specific resistance. Connect a sensor cable between terminals 1
and 7.
*2. Two Electrodes can be connected to the 61F-HSL. Use them for an alarm, not for creating a self-holding circuit.
*3. The length when using completely-insulated, 600-V, 3-conductor (0.75 mm²) cabtire cables. Usable cable lengths
will become shorter as the cable diameter or number of conductors becomes larger. For more details, refer to Safety
Precautions for Floatless Level Controllers.
*4. It is recommended that the cable length be kept as short as possible since the Electrode circuit current is at DC
micro-current level. Moreover, the Electrodes will corrode rapidly if the current is allowed to constantly flow between
the Electrodes.
Be careful with the electrode polarity and grounding when wiring.
