Question
How do you measure the resistance between
electrodes?
Answer
The
resistance cannot be measured using a tester, so you need to measure the
current between the electrodes with an ammeter that is capable of
accurately reading values around 1 mA (with impedance as low as possible),
and then measure the voltage between the electrodes with an ohmmeter that
is capable of reading values down to a few volts (with impedance as high
as possible). When you have these values, use Ohm's law to calculate the
resistance.
* Measure with E1 and E3 wired to the
61F Level Controller.
