View frequently asked questions in your country.
Is it possible to use a commercially available terminal block or to make one yourself, instead of using the one that comes with the K7L?
How long is your longest Liquid Leakage Sensing Band? Also, how do you join two Bands together?
Can the K7L detect pure water?
Which Controller model is best for simple liquid-level detection without pump control?
It seems that the 61F’s electrodes are dirty and sensitivity has dropped. How can I clean them?
Can the K7L be used as a substitute for the 61F-GPN-V50 Water Leak Detector?
What is the two-wire operating principle of the 61F-[]R Controllers?
How does the 61F Controller operate when power is restored after a power interruption?
What is the voltage between the 61F Controller’s electrodes?
Can the K7L detect oil?
Can two 61F Controllers and two Electrode Holders be used in the same tank?
What is Interelectrode resistance?
How is the electrode or electrode band mounted to the PS-[]S Electrode Holder, and what parts are required?
Are there any precautions to observe when controlling pure water with a 61F Controller?
What kind of wiring is best to combine a 61F-GP-N Controller and float switch?
Is it possible to connect more than one 61F Controller to the same electrodes and share the electrodes?
When voltage is applied to the 61F Controller, it operates regardless of the actual liquid level. What is the cause of the problem and how can it be corrected?
Is it acceptable to wire the 61F Controller’s electrode cable and power cable in the same duct?
With a 61F-G1, the water level of a water supply is above the E2’ height, but the pump does not operate. What is the cause of the problem and how can it be corrected?
The 61F Controller’s power supply is ON, but the Controller does not operate even though the liquid level reaches the detection level. What could be causing this problem?
Can a single K7L Amplifier be used to detect leakage at multiple locations?
Which 61F Controller is best to use for a PLC input? Pump control is being performed by the PLC.
Why is the long common electrode always grounded in the 61F Controller’s connection diagrams?
Can a 61F-GPN-V50 Leak Detector and Electrode be used as a set?
Is it acceptable to use a steel tank as the ground electrode and not use the 61F Controller’s ground electrode?
Why do the specifications for the 61F High-sensitivity Controller say, "possible to use with 15 k-ohm or less, however, this may cause reset failure"?
How do you measure the resistance between electrodes?
What does operation resistance mean?
