Basic Tools
This is a list of basic tools required to repair almost any problem encountered with a control base. Tools
such as a digital multimeter and clip-on ammeter are used to test the electrical current of various
components on the control base. Psophometers are used to test certain components based on the
loudness of the sound they produce. Water thermometers check the temperature of the spa’s water and to
verify readings provided by the system’s internal thermometers. Screwdrivers and wrenches will help you
disassemble and reassemble the unit.
