What position should the Model 3604 Thermo Unit's power control switch be placed in before plugging the power cord into an electrical receptacle?

• A. On
• B. Off
• C. Standby
• D. Active

Answer: (B)

The correct position for the Model 3604 Thermo Unit's power control switch to be in before plugging the power cord into an electrical receptacle is "Off." This practice is a crucial safety precaution. Keeping the power switch in the "Off" position ensures that there is no electrical flow to the unit when connecting it to the power supply. This approach helps prevent any potential electrical shocks or damage to the unit that could occur if the device were to be activated inadvertently during the plugging process. In calibration and maintenance tasks, always ensuring that equipment is de-energized before connecting or disconnecting power is a standard safety protocol. Being aware of this practice reduces the risk of accidents and injuries, making it essential for any technician working with electrical equipment.
