Test Point Voltages.

WARNING: Before taking magnetron current readings, turn the unit off. Check resistance between “MAG CURRENT” test points.

Reading should be approximately 40K Ohms. If this value is not correct, do not attempt current reading. Damage could result to the meter or personnel injury could result. Contact Fusion UV Systems Customer Service if 40K Ohms reading is not obtained.

After checking resistance, be sure to switch the meter to correct setting for DC voltage reading.
