Batterie)14 Intended use This electronic material moisture measuring device uses the capacitive meas- uring principle and is suitable for non-destructive location and evaluation of moisture distribution in walls, oors and ceilings. The device provides an overview of the extent, distribution and severity of the moisture damage as part of a building survey. It can be used in the material-independent INDEX mode or the additional Building Material mode. Material characteristics are available for cement screed, anhydrite screed, and concrete which can be displayed as a CM % or mass %. This climate sensor allows the device to be used as a hygrometer and provides other relevant parameters for analysing the damage and moisture behaviour using the ambient temperature, humidity and calculated dew point. The measured data can be transferred to a smart phone via the digital connection interface. Completely read through the operating instructions, the "Warranty and Additional Information" booklet as well as the latest information under the internet link at the end of these instructions. Follow the instructions they contain. This document must be kept in a safe place and if the laser device is passed on, this document must be passed on with it.

The integrated material characteristics correspond to the specified building materials and their designation. Building materials of the same type but with different designation / composition / strength / density can however affect the measurement result. Furthermore, building materials will vary from manufacturer to manufacturer due to the way they are produced. This is why, in the event of different product compositions or unfamiliar construction materials, a one-off comparative moisture measurement should be taken using methods that can be calibrated (e.g. kiln-drying method). If different measured values occur, they should either be viewed relatively or the index mode for moisture/drying behaviour should be used.

Selecting the material The classification "dry" means that materials in a heated room have reached a balanced moisture level and are thus suitable for further processing.

Green = dry Yellow = moist Red = wet In addition to the numerical display of the measured value in % relative material moisture, the LED display provides an additional visual evaluation of the moisture. Fixed material characteristics are stored for cement screed, anhydrite screed and concrete. In INDEX mode, you can set an individual threshold value. The LED display bar becomes larger, from left to right, with increasing moisture content. The 12-position LED display is subdivided into 4 green (dry), 3 yellow (moist) and 5 red (wet) segments. Wet material causes an additional acoustic signal. Wet/dry LED display ENMultiWet-Finder Plus

MAXREFCALCMCMCM MENU The device starts automatically in Index mode and does not always need to be calibrated to zero in mid-air to compensate environmental inuences. The spherical measuring head must not be in contact with the user's hands or other objects during calibration. For zero calibration, hold down the ‘FIND’ button and hold the device in a free space. Continue to hold the ‘FIND’ button down after the beep and position the spherical measuring head perpendicular to the item to be measured. Once the measured value appears in the display, release the ‘FIND’ button. The measured value is retained automatically. Hold down Measuring process Index mode is used to rapidly locate moisture with comparative measurements, without a direct output of material moisture in %. The output value (0 through 199.9) is an indexed value that increases as material moisture becomes greater. Measurements made in index mode are independent of material type and particularly useful with materials for which no characteristics are stored. When comparative measurements reveal strongly deviating values, the course of moisture in the material can be localized quickly. Index mode

40 mmREF function Hold down – Contamination should be removed from the measurement location before measuring.– The device requires approx. 15 minutes to acclimatise to the ambient temperature, depending on the location.– Always hold the spherical measuring head against the item to be measured with a constant pressure.– Do not tilt the device during the measuring process, do not slide it along the item to be measured, and do not lean on the device.– The raw density of the item to be measured has a considerable inuence on the result of the measurement; the higher it is, the higher the measured value determined. – Rough surfaces lead to a lower measured value being displayed. – If the sensor detects metal (e.g. pipes, screws, wiring) in the item to be measured, this results in a signicantly higher measured value which cannot be used. – When positioning the spherical measuring head in corners, a higher measured value is displayed than on at surfaces as the spherical measuring head is in contact with more material. A distance of 10 cm must be maintained from corners.– The percentage measured values in material mode are trends and do not replace, for example, precise checking of the readiness of screed for covering.– To ensure correct measurements are taken, the climate sensor must not be covered by the hand.Information on use

MENU Hold down Holding down the ON/OFF button and the MAX button at the same time takes you to the menu. The dry limit value, alarm and automatic power off can be set from here. Settings menu The device can only retain a MAX value as part of a measuring process. The MAX value is displayed after the measuring process. The MAX value and the current value are displayed by holding down the ‘FIND’ button during a new measurement. MAX function

The Reference function allows you to gain an overview of the moisture distribution in the wall. Find a dry point on the item to be measured and determine the moisture content as described in section 6 “Measuring process”. Fix the measured value as a reference value by pressing the ‘REF’ button. Then complete a moisture measurement elsewhere. This gives you an overview from the reference value, maximum measured value and current measured value.

Setting the dry limit The wet/dry LED indicator is programmed in line with the relevant material characteristics so the LEDs also provide information about whether the material should be classied as dry, moist or wet. Holding down the ‘MODE’ button and the ‘MAX SET’ button at the same time takes you to the menu. Pressing the ‘MAX SET’ button allows you to set the dry limit only in INDEX mode. This limit value must be established away from the specic point of use. As soon as Building material mode is selected, the LED display appears based on the saved material parameters.

MENU Pressing the ‘MODE’ button allows you to switch the acoustic alarm and the wet/dry LED display on and off.MultiWet-Finder Plus
