Place the fluorescent bulb inside the chamber. Leave the door open (this test is performed at atmospheric pressure). Turn on the main power, wait 10-15 seconds, and turn on the RF power (start at HI, followed by MED, followed by LOW), waiting up to 10 seconds at each RF power level. If the bulb glows on all three RF power settings, the electronic system is functioning properly; proceed to test the vacuum system.
If the electronics test fails, contact Harrick Plasma.
