TECH 101 & ETSD / Electronics Testing & System Diagnostics Training Class

This full day course provides a great technical overview of Fujitsu’s H-series products while complimenting it with application ideas, installation hints, tips, and requirements. Students will learn about the new R-32 mini split options offered by Fujitsu.  In addition, the Electronics Testing & System Diagnostic (ETSD) portion of this class will provide in-depth troubleshooting for H-series Inverter systems. This will be a HANDS-ON portion of the course offering a guided teardown of a typical wall-mounted indoor unit, and classroom style training on multi-meters, DC controls and circuits with diagnosis and testing of Fujitsu outdoor unit circuit boards.

Required to Bring to Class:  Students need to bring a digital multi-meter with fresh batteries to the class. Multi-meter should be capable of specific component testing; this includes the diode check function and a 4 to10 mega-ohm testing capability.

Seating is limited to the first 20 students!
