  • Page 15: Chapter 1. Getting Started

    Chapter 1. Getting Started Chapter 1. Getting Started The GE PM880 is a versatile, battery-powered portable hygrometer that is designed for spot sampling moisture measurements. Although the PM880 offers many options, it requires only battery charging and minimal setup to begin taking measurements.

  • Page 16: Charging The Battery Pack

    The PM880 is powered by a rechargeable NiMH battery pack. When you receive the PM880, you will need to fully charge the pack. The pack must be charged for 4-5 hours, until the amber LED on the charger goes out, to receive the maximum charge.

  • Page 17: Configuring The Battery Charger

    Chapter 1. Getting Started 1.1.2 Configuring the Battery Charger The PM880 battery charger has a switchable voltage input of 115 to 230 VAC. Make sure the voltage selector is in the correct position before plugging it in. The battery charger is intended for indoor use only.

  • Page 18: Charging The Battery Pack

    When you receive your unit, you should completely charge the battery pack before using it for the first time. Remove the pack from the charger and reinstall it in the PM880. Refer to Checking the Battery Status on page 133 for details on monitoring the battery.

  • Page 66: Using Automatic Calibration (Autocal)

    The PM880 automatically calibrates the moisture and pressure measurement circuitry (AutoCal) at a user-selected interval. Autocal compensates for any drift in the electronics. GE recommends setting the AutoCal interval to 8 hours. Set a smaller AutoCal interval more frequently if the meter is exposed to extreme temperatures or weather conditions.
  • Page 67 See the example below. EXAMPLE: The PM880 establishes a fixed schedule, beginning at midnight, using the interval specified to determine the times of subsequent AutoCals. If you enter an 8 hour time interval, AutoCal will occur 3 times per day (1 day = 1440 minutes/480 minutes = 3).
