Test Circuit
Select the resistance R shown in the test circuit diagram according to
the K6EL’s rated sensed current. Change the current using the slidac
and ascertain the K6EL’s operating value each time by reading the
ammeter.
For example, R could take the values shown below:
30 mA: 3.3 k , 6 W
100 mA: 1 k , 20 W
