Introduction

Congratulations on your purchase of the Extech MO270 Moisture Meter with full graphical display.

This meter includes MeterLinkTM Bluetooth capabilities for use with FLIR infrared cameras (such as

FLIR T/B200, T/B300, T/B360, T/B400 or i/b60 cameras). The MO270 detects moisture in wood

and other materials such as particle board, carpeting, and ceiling/bathroom tiles using a non-

invasive method (pinless); the MO270 also measures moisture in sheet rock and other building

materials using the pin method. This meter is shipped fully tested and calibrated and, with proper

use, will provide years of reliable service.

Features

Detachable sensors transmit data viewable on meter display from up to 65ft (20m)

Readings from up to eight (8) remote sensors can be viewed on meter

Meter can record data from up to forty (40) remote sensors simultaneously onto SD card

Wireless sensor affixes to 4 ft (1.2m) telescoping handle; Optional longer handles available

Wirelessly transmit moisture data to FLIR IR cameras via MeterLinkTM and Bluetooth

Wood Moisture equivalent (%WME) pin readings

Visual and audible High and Low Alarm modes

2-point calibration check built into protective cap

Includes 3.7V rechargeable Li-Polymer battery, wireless moisture sensor, external pin probe,

replacement pins, telescoping handle, AC adaptor, protective cap, 2G SD card, and hard case

Setup

Getting Started

1. Charge the sensor and the meter batteries (refer to following section for full details on

battery charging).

2. To switch the meter ON, press and hold the button for 3 seconds; the navigation buttons

will illuminate and the display will switch ON. To power OFF, press and hold the power

button for 3 seconds.

3. The F1, F2 and F3 buttons are ‘soft keys’ meaning that their functions change with the

particular mode or screen that is active.

5. The “OK” button is used to select the highlighted menu function.

Charging the Batteries

1. Charging will begin once the USB cable is connected between the mini-USB port on the

Sensor or the Meter and a PC USB port or an AC outlet. Connecting only the Meter USB

port charges both the Meter and the Sensor simultaneously (while they are physically

connected to each other).

2. Note that if you connect the meter to the PC via the USB port before switching the meter

ON, the meter screen will show these 3 selections when it is powered up:

PC CAM (reserved for future use)

Disk Drive (select this setting to view the meter’s stored readings on the PC using

optional WindowsTM software)

Charger (select this setting if the connection to the PC is to be used for charging

purposes)

3. To check the battery status:

a) Press and hold the button for 3 seconds to switch the meter ON.

b) The USB menu will appear. Navigate down to “Charger” and press OK.

c) The digital display measurement screen will appear showing the two battery icons at

the upper right side of the display.

d) The (Meter) and (Sensor) icons will be completely filled when the batteries are

fully charged.

Operation

Basic Operation for Pin Measurments

CAUTION: The electrode measurement pins are extremely sharp. Use care when handling this

instrument. Cover the pins with the protective cap when the instrument is not in use.

1. Remove the protective cap to expose the electrode pins.

2. Press and hold the key for 3 seconds to switch the meter ON.

3. If the icon is displayed, proceed as follows to switch to the icon.

a) Press the MENU (F1) button and navigate to the WME/REL box.

b) Press OK, select WME, press OK and press EXIT.

4. Carefully push the electrode pins a minimum of 0.07” (2mm) into the material under test.

Note that the pins should be inserted into wood perpendicular to the wood’s fiber structure.

For high moisture readings, it may take several minutes for the meter reading to stabilize.

5. Take several readings in several locations on the material for the best representation of the

amount of moisture present.

6. Read the measurement values on the display

7. Replace the protective cap when finished.

Basic Operation for Pinless Measurments

1. Press and hold the key for 3 seconds to switch the meter ON.

2. If the icon is displayed, proceed as follows to switch to the icon.

a) Press the MENU (F1) button and navigate to the WME/REL box.

b) Press OK, select REL, press OK and press EXIT.

3. Press and hold the key for two seconds to switch the meter OFF

4. Keep hands and any surface away from the rear sensor and then press the key to

switch the meter ON. The meter will auto-zero during power-on.

5. The pinless moisture detector is located at the rear of the instrument, just behind the display.

6. Place the meter so that the rear sensor lays flat against the surface of the material under

test.

7. Take several readings in several locations on the material for the best representation of the

amount of moisture present.

8. Read the measurement values on the display.
