Page 9: Capacitance (Mfd)
MicroAmps DC (µADC) Test flame rectifier diodes on a heater control. Connect leads between flame sensor probe and control module. Turn heating unit on. When the flame is on, there should be a measurable µADC signal, typically under 10µADC. Compare measurement to manufacturer’s specification to determine if replacement is necessary. -
Page 10: Resistance (Ω)
Used for “ohming out” a compressor. A 0.01Ω resolution is useful to test the resistance between the terminal poles because the values are typically very low. For best practice, use a megger (Fieldpiece SMG5) to measure motor winding insultion to ground.
