TROUBLESHOOTING*
The relays and 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 8).
