The equipment that you bought has required the extraction and use of natural resources for its production.
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.
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.
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.
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.
1.2.1 Powering On To turn the PM880 on, press the red button in the upper-right-hand corner of the keypad. Immediately upon powerup the PM880 displays a series of messages and performs various checks. The screen then appears similar to the one shown in Figure 1.
Chapter 1. Getting Started 1.2.2 Powering Off To turn the PM880 off, press the red key for 3 seconds. The screen now appears similar to Figure 2. Press to shut down the PM880. [F1] Figure 2: Shutdown Menu Model PM880 Portable Hygrometer User’s Manual...
1.4 Entering Setup Data For immediate operation, the PM880 requires only a moisture probe and its corresponding calibration data. You should enter data for each site where you plan to make a measurement. Once entered, you can save it into a file that can be recalled at the measurement site.

[ENTER] prompt asks you to select a time period for the next probe calibration. The PM880 will display a calibration reminder for the probe based on the last calibration date. GE recommends recalibrating a probe a minimum of once a year.
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).
Chapter 4. Using Special Features 4.7 Entering Constants and User Functions The PM880 enables you to enter two types of constants, a user constant and a saturation constant, as well as user-defined functions and tables to manipulate data.

The Moisture Image Series probes, when operated with an ATEX certified PM880, are intrinsically safe and can be used in zone 0 areas. The Moisture Image Series probes measure moisture content in a standard range from –110°C to 20°C (–166°F to 68°F) dew/frost point temperature and optionally from –110°C to 60°C (–166°F to 140°F).
The M and the TF Series probes are connected to the analyzer with a special GE shielded cable. Probes can be located up to 600 meters (2,000 feet) from the PM880 (consult the factory for distances up to 1,200 meters). To measure pressure with a TF probe, the maximum cable length is approximately 152 meters (500 feet).

There are a variety of environmental and installation factors that can affect measurements. These factors should be discussed with a GE applications engineer or field sales person by the time you receive the PM880. However, if you decide to add additional measurement sites, this section contains some basic guidelines for selecting a measurement site and constructing a sample system.
Observing these few simple precautions will result in a long and useful probe life. GE recommends that probe calibration be checked routinely, at 12-month intervals, or as recommended by our applications engineers for your particular application.
