REED R9900 User manual

  • Hello! I've reviewed the user manual for the REED Instruments Indoor Air Quality Meter R9900. I understand it measures CO2, temperature, and humidity, and has features like a backlight, data hold, and alarms. I am ready to answer your questions about the device and its operation.
  • How long does the meter take to warm up?
    How often are readings updated?
    How do I hold the readings on the LCD?
    How do I activate the backlight?
    How do I set up the audible alarm?
    How do I perform a CO2 calibration?
