Current Measurements
Apply power to the 2015A and measure the currents. They should be within the fol-
lowing ranges:
+24 V dc
40 to 0 mA
+12 V dc
150 to 170 mA
– 12 V dc
60 to 80 mA
– 24 V dc
40 to 60 mA
Note:
A greater deviation in currents indicates a faulty unit. Gross errors would
probably be due to faulty or reversed capacitors, shorted or open AMP Out-
put transistors, etc.
