Question
How is the resistance between electrodes of the Level Switches measured?
Answer
How to measure the resistance between electrodes
Since the resistance between electrodes cannot be measured by a tester, use an ammeter able to read approximately 1mA with as low an impedance as possible and a voltmeter able to read a value of several volts with as high an impedance as possible to measure the current and voltage between electrodes.
Calculate a resistance value from the measured voltage and current values by using Ohm's Law.
As for the resistance between electrodes, refer below.
* Perform the measurement while the Floatless Level Controllers "61F" unit is wired to each end of electrodes E1-E3.
An ammeter able to read approximately 1mA with as low an impedance as possible.
A voltmeter able to read a value of several volts with as high an impedance as possible.
