Getting Started
The GE Infrastructure Sensing PM880 is a versatile, batterypowered portable hygrometer that is designed for spot sampling
moisture measurements . Although the PM880 offers many
options, it only requires battery charging and minimal setup to
begin taking measurements.
This chapter is desi gned to provide a st ep-by-st ep guide t o getti ng
the meter up and running as quickly as possib le. Additional
programming options are dis cussed in later chapters.
Follow the sections in this chapter to setup your meter. This
chapter includes the fo llowing information:
• Charging the batteries
• Powering On and Off
• Entering Data Using the Keypad
• Entering Setup Data
• Displaying Measurement s
• Saving Data in Site Files

Charging the Battery Pack
The PM880 is powered by a rechargeable NiMH battery pack.
When you receive the PM880, you will need to fully char ge the
pack. The pack must be charged 4-5 hours until the amber LED
on the charger goes out to rece ive the ma ximum charge. Wh en
fully charged, the pack provides 16 to 24 hours of continuous
operation, depending on the probe type and PM880 usage. An
internal batter y gauge indicates the remaining power in the pack.
Before you charge the battery pack you must make sure the
charger is proper ly configured. Use the instructions below to
properly char ge the battery pack.
Removing the Battery Pack
1. Make sure you are in a general-purpose location where you
can safely charge the pack .
!WARNING!
THE BATTER Y PACK CA N BE I NSTALLED
AND REMOVED IN HAZARDOUS AREAS,
HOWEVER, IT MUST BE CHARGED
IN GENERAL-PURPOSE AREAS ONLY.
2. Remove the four thumb screws on the back panel of the
PM880 that secure the pack.
3. Lift the pack out of the unit.

Configuring the Battery Charger
The PM880 battery charger has a switchable voltage input of 1 15
to 230 VAC. Before you plug the pack into the charger you must
make sure the voltage selector is in the correct position before
plugging it in.

Charging the Battery Pack
1. Plug the pack into the battery charger.
2. Connect the charger to AC power. When power is applied, the
amber LED glows and the charger automatically begins
charging the pack.
3. The pack is fully charged when the amber LED goes out
(approximately 4-5 hours).
IMPORTANT:
4. Remove the pack from the charger and reinstall it in the
PM880. Refer to Checking the Battery Status on page 8-4 for
details on monitoring the battery.
When you receiv e your unit, you should
completely charge the battery pack before you
use it for the first time.

Entering Setup Data
For immediate operation, the PM880 requires only a moisture
probe and its corresponding c alibration 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 recalle d at the
measurement site. Use the sections that follow to program your
meter.
Note:
The PM880 has a dditional menus that e nable y ou to tailo r

Entering Calibration Data
The PM880 needs moisture and/or press ure calibration data for
probes. You need to enter this data
• when setting up a new unit
• sent a probe(s) back to the factory for calibration
Be sure you have the Calibration Data Sheets that are supplied
with each GE Infrastructur e Sensing probe. Each Calibration
Data Sheet consists of a list of data points that you will need to
enter or verify, and lists its corresponding probe serial number.
Calibration Data Sheets are usual ly packed insi de the probe cases.
Since the PM880 enables you to use more than one probe, the
meter provides a place to enter the probe serial number to help
you match the probes to the corresponding site files. The probe
serial number is stored as part of the site file.
Use the sections on the following pages to enter the serial
number, moisture and pressure calibration data for the probes.
Entering Probe ID
1. If the menu is not active, press [MENU].
2. Use the arrow key to scro ll to Program and press

PM880 memory when needed.
Note:
It is not necessary to enter cali bration data for the
Moistur e Image Series (MISP) unless you send the probe
back to the factory for calibr ation without its electronics
module. If this is the case, you must manually ent er the
calibration data as described below.
Enter moisture calibr ation data (MH or FH) and dew point
readings (up to 20 data points) for the moisture probe as
described below. Refer to Figure 1-9 on page 1-19 for a menu

Taking Measurements
The PM880 hygrometer is part of measurement system that
consists of the electronics, cable, probe and optional sample
system. Once the electronics are properly prog rammed, you must
connect the sample system and probes to begin taking
measurem ent s . This chap ter dis cu ss es the ste p s neede d to beg i n
taking basic measurements.
Note:
Refer to Appendix A, Measurement Considerations, for
more information on selecting measurement sites and
sample system construction.

Installing the Probe into a Sample System
Moisture probes are inst all ed into a portable sample system. The
sample system pro tects the probes fro m coming into contact with
damaging el em en ts in the proc es s.
Caution!
If you are mo un t in g th e moist u re probes d ire ctl y in t o th e
process line, you must consult GE Infrastructure Sensing
for proper installation instructions and precautions.
To install a moisture probe:
1. Screw the probe into the receptacle fitting, making sure not to
cross thread it. Insta ll moisture probes with dif ferent fit tings in
the appropriate manner.
Note:
2. Hand-tighten the probe in a clockwise direction , then tighten it
Stand ard moisture probes have a sintered stainless-steel
shield that protects the aluminum oxide sensor. Leave the
shield in place for maximum protection.
