How can I test an ISC Converter?

You can test the ISC converter by simulating a conductivity reading using an ISC40 sensor.

  • You will need:
    • A known working ISC40 sensor.
    • A piece of wire
    • One or two decade box/resistance sources.
  • Connect sensor wires 13-17 to analyzer.
  • Connect wire through the toroidal sensor and connect the wire to the decade box. Be sure not to cross the leads or wire.
  • Use second decade box resistance source to simulate the temp sensor.
    • If you don’t have a second resistance source you can just connected the temp sensor wires 11&12 from the sensor, you will just not be able to vary the input readings.
  • Write down the Cell Constant, change it to 1.000
  • Set the temperature to the reference temperature or: Write down the Temp. Compensation method, and change it to “None.”
  • The Conductivity reading should be 1/R where R = Resistance on the decade box.
  • If you need higher resistance than the decade box you can use multiple loops of wire through the sensor.  The reading will be L2 / R where L = Number of loops, R = Resistance on the decade box.
  • Return all settings to the original settings when finished.
