How does the Fluke 561 Infrared Thermometer turn on?

• A. By Pressing The Trigger
• B. By Tapping The Screen
• C. By Connecting To A Power Supply
• D. By Voice Command

Answer: (A)

Squeezing the trigger is the way this handheld infrared thermometer is designed to power up. The trigger acts as the primary control and doubles as the on/off mechanism. When you press it, the device wakes its internal electronics, starts sampling with the infrared sensor, and updates the display with the temperature reading. This keeps the tool quick and portable, since it is typically battery-powered and doesn’t need a separate power button, screen tapping, external power, or voice commands to turn on. Tapping a screen isn’t applicable because most Fluke IR thermometers don’t use a touchscreen, and plugging into a power supply is only for charging or extended use, not the normal on switch.
