FAQ

1. Q: How often should I use the auto zero mode?
   A: The auto zero mode should be used periodically within a time range of 10-15 minutes to calibrate the humidity sensor readings to zero and avoid deviations in measurements.

2. Q: What should I do if the display remains blank?
   A: If the display remains blank, check the battery status indicator for low battery voltage and replace the batteries if needed.

INTRODUCTION

On the front panel, there is a digital display (see picture) and a keyboard consisting of six buttons (see picture). The humidity sensor is located under the back panel of the device. The device is powered by 2x AAA alkaline batteries, housed in the battery compartment at the lower back part of the device.

APPLICATION FIELD

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

• 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.

• The device produces with averaged characteristics settings.

• Operating temperature: +5 … +40°C, with several humidity till 90% at the temperature 25°C and air-pressure 86 … 106 Pa.

OPERATION

TURN ON/OFF THE DEVICE

• Turn the device on by briefly pressing the HOLD/ON button. If the display remains blank or the battery status indicator shows low battery voltage, replace the power supply.
• To turn the device off, press and hold the OFF button until the device powers down.
• If no buttons are pressed for 20 seconds, the screen backlight will turn off. You can reactivate it by pressing any button.
• The device will automatically  turn off after 1 minute of  inactivity.

AUTO ZERO MODE

If you press button ZERO/SET, the device will enter auto zero mode. The following information will appear on the screen:

At this point, ensure the sensor of the device is at least 30 cm away from all objects, then press the ZERO/SET button again. The device will perform auto- tuning and then switch to measuring mode, as shown in the picture.

Using auto zero mode, you calibrate the humidity sensor readings to zero. To avoid deviations, the auto zero mode should be used periodically, within a time range of 10-15 minutes.

MEASURING MODE

After selecting the material using the / button and the material group using the button, place the sensor plate on the testing surface. To obtain accurate readings, ensure that the sensor fits snugly against the test surface, with no gaps between the sensor and the surface. Then, read the result.
The surface should be even, clean, and homogeneous, without deep dents or protrusions. While obtaining measurements, the device should be pressed lightly against the test surface with a force of about 1 kg.
To hold the result on the screen, for example, when measuring a surface where you cannot see the device, press the HOLD/ON button. “HOLD” will appear at the top of the screen, and the last measured value will remain visible until you press the HOLD/ON button again.
Moisture measurement results can be obtained for:

• Wood
  arithmetic mean of more than three measurements

• Concrete
  arithmetic mean of more than five measurements

The measuring depth is 15-20 mm, depending on the moisture content and density of the material being measured. The device is calibrated for this depth. If the thickness of the chosen material is less than 15 mm, perform the measurement by holding the device with the material in the air to ensure the sensor does not pick up data from other materials.

To avoid deviations, use the auto zero mode  (refer to “AUTO ZERO MODE”).

SENSOR TEMPERATURE UNITS

If you hold the   button, the temperature unit changes from Celsius to Fahrenheit. A second long press will change it back to Celsius.

MAINTENANCE

Users should perform periodic preventive measures and checks.

• Keep the device clean and protected from bumps, dust, and moisture; wipe it with a clean, soft cloth after each use.
• If the battery status indicator shows low voltage, turn off the device and replace the power supply.
• Optimize battery life by turning on the device before measuring and turning it off after use.
• If the device becomes unresponsive during operation and does not turn off, open the battery compartment for a few seconds, remove one battery, reinsert it, and restart the instrument.
• If the device does not respond when turning it on, remove the batteries, clean the battery contacts with an alcohol-soaked swab or fine sandpaper, reinsert the batteries, and check if the device functions.
• Repairs must be conducted by authorized after-sales service centers. The device is a highly technical product and should not be repaired by users; therefore, we do not provide complete technical documentation to users
• For long-term storage, remove the batteries from the compartment to prevent damage from leakage.
