TROUBLESHOOTING
The switches contained in the One Series are electronic. The on/off switch signal is produced by a transistor or a solid-state relay, depending on the
One Series model. Electronic switches cannot be properly tested with an ohmmeter. Instead, measure the voltage drop across the switch connected
to the intended load to determine if it is open or closed. A properly functioning One Series electronic switch will exhibit the following voltage levels
(see Table 5):
