Futech HYDRO - Moisture Meter Manual

Introduction

User's manual contains information about operating, functions, technical specifications and other important information for user. The instrument is designed for moisture measurement of wide ranges of solid materials such as concrete (4 groups) wood (8 different groups).
Carefully read the User Manual before using this product.

APPLICATION FIELD

1. The device is made for the rapid moisture testing of various types of wood and concrete. The device measures the moisture content of a material, judging by its electrical resistance at a temperature above 0°C. Variety of measuring items:

• 8 groups – wood
• 4 groups – concrete (light and heavy), concrete blinding coat. Full list of material groups you can find in the application 1.

2. The main application field: various kinds of timber works, as well as construction production and technologies, in which the humidity of materials regulated by normative-technical or technical documentation.
3. The device produces with averaged characteristics settings.
4. Operating temperature: +5... +40°C, with several humidity till 90% at the temperature 25°C and air-pressure 86... 106 Pa.

FUNCTIONS

On the front panel there are digital display (see picture), and the keyboard that consists of 6 buttons (see Picture), humidity sensor located under the back pane of the device. Batteries located into the battery compartment in the back low part of the device.

WERKING

Operation

1. Turn on/off the device
   Turn the device on with short press on the button HOLD/ON. If there are no information on display appeared or the battery status indicator shows low battery voltage, change the power supply. To turn the device off press and hold the button /OFF until the device turns off.
   The device will turns off automatically after 1 minute if you do not press any button.
   At this point the sensor of the device should be taken away from all objects on 30cm and press the button ZERO/SET again. The device will make the auto tuning and goes to the measuring mode, see the picture.
   
   Using auto zero mode you set up the humidity sensor readings to the zero. To avoid deviation the auto zero mode should be used periodically (time range 10-15 minutes).
2. Measuring mode
   After choosing the material by button and the material group by button put the sensor plate on the testing surface. To obtain accurate readings it is necessary to ensure that the sensor fits to the test surface (between the sensor and the surface should be no gaps), and after reads the result.
   The surface should be even, clean and homogeneous, without deep dents and protrusions. The device should be slightly pressed to the test surface with a force of about 1kg while obtaining the measurements. Moisture measurement results can be obtained for:
   • Wood – arithmetic mean of more than three times measurement
   • Concrete – arithmetic mean of more than five times measurementThe measuring depth is 15-20mm which depends on moisture and density of the measuring material (the device equipped with calibration setting on this depth). If the thickness of the chosen material is less then 15mm, the measurement should be carries out with holding device with material on the air, so that the sensor do not get information on the other materials.
     To avoid the deviation use the auto zero mode (refer to the 4.2)
3. Sensor temperature units
   If you hold the button , the temperature unit changes from Celsius to Fahrenheit, and with second long press it changes back.

MAINTENANCE

1. Preventive measures and checking should be periodically done by users
2. Keep the device clean and protected from any bumps, dust and dampness; wipe it with a clean and soft cloth.
3. After using remove all the dirt, thus etc., from the device.
4. If the battery status indicator shows low battery voltage, turn off the device and change the power supply
5. To optimize the battery discharge time, turn on the device before measuring and turn it off after using.
6. If during operation the device does not respond to the keystrokes and does not turn off, open the battery compartment for a few seconds, remove one of the batteries, insert it back and re-start the instrument.
7. If the device does not respond to the turn on button, remove the batteries from the device; wipe the battery contacts with alcohol-wetted swab or clear it with fine sandpaper, insert the batteries back and check if the device works again.
8. Repair must be carries out by authorized after-sales service centres.
9. In case of long-term non-use, remove the power supply from the battery compartment in order to avoid the damage of the device by leaked fluid. The device is a highly technical product and should not be repaired by its users, that is why we do not supply users with a complete technical documentation of the device.
