1. Safety instructions

This chapter gives general rules which must be followed and observed if the product is to be handled safely. Avoiding personal injury/damage to equipment i Do not use the measuring instrument and sensors to measure on or near live parts. i Never store the measuring instrument/probe together with solvents and do not use any desiccants. Product safety/preserving warranty claims i Operate the measuring instrument only within the parameters specified in the Technical data. i Always use the measuring instrument properly and for its intended purpose. Do not use force. i Do not expose handles and feed lines to temperatures in excess of 70 °C unless they are expressly permitted for higher temperatures. Temperatures given on probes/sensors relate only to the measuring range of the sensors. i Open the instrument only when this is expressly described in the documentation for maintenance and repair purposes. Carry out only the maintenance and repair work that is described in the documentation. Follow the prescribed steps when doing so. For safety reasons, use only original spare parts from testo. Ensure correct disposal i Take faulty rechargeable batteries/spent batteries to the collection points provided for them. i Send the product back to testo at the end of its useful life. We will ensure that it is disposed of in an environmentally friendly manner.

This chapter gives the areas of application for which the product is intended. Use the product only for those applications for which it was designed. Ask testo if you are in any doubt. The product was designed for the following tasks/applications:

• Fast and non-destructive evaluation of material moisture courses in woods and building materials. Does not replace reference methods such as CM method or Darr-Wäge (dry-and-weigh) method. The instrument is not calibratable. The product must not be used in the following areas:

• Areas at risk of explosion. Materials subject to electrical voltage. Electric sshock! If in doubt, check whether the materials are energized before the measurement (e.g. in the event of water damage in walls)3. Product description 21

Product description22

Voltage is supplied by means of a 9 V monobloc battery (included in delivery) or rechargeable battery. It is not possible to run the instrument from the mains supply or charge a rechargeable battery in the instrument.

3.3 Humidity measurement

procedure The non-destructive stray field measurement uses the ability of water molecules to dampen and thus change electromagnetic fields. The electric field penetrates the material via the contact plates and creates a measuring field with a depth of approx. 5 cm (2”). The following factors can influence the measurement result: Factors Ideal condition Measurement depth Material thickness > 5 cm (> 2”). Caution: The upper layers of the material influence the measurement result more than the deeper layers. Material surface As level as possible as contact plates should lay flat against it. Material properties As homogeneous as possible with no air pockets. Moisture distribution As even as possible. Metals and electric fields None, if possible.4. Commissioning 23

This chapter describes the steps required to commission the product.

Inserting aa bbattery/rechargeable bbattery: 1 To open the battery compartment on the rear of the instrument, push the lid of the battery compartment in the direction of the arrow and remove it. 2 Insert a battery/rechargeable battery (9 V monobloc). Observe the polarity! 3 To close the battery compartment, replace the lid of the battery compartment in position and push it against the direction of the arrow.

This chapter describes the steps that have to be executed frequently when using the product.

Switching tthe iinstrument ooff: i Press and hold (for approx. 2 s) until the display goes out.

5.3 Performing settings

To oopen cconfiguration mmode: The instrument is switched on and is in measurement view. Hold, Max or Min are not activated. i Press and hold (for approx. 2 s) until the display changes. - The instrument is now in configuration mode. You can change to the next function with . You can leave configuration mode at any time. To do so, press and hold (for approx. 2 s) until the instrument has changed to measurement view. Any changes that have already been made in configuration mode will be saved.

To sset AAuto OOff: Configuration mode is opened, AutoOff is flashing. i Select the desired option with / and confirm with :

• on: The measuring instrument switches off automatically if no key is pressed for 10 min. Exception: A recorded reading is shown on the display (Hold or Auto Hold is lit).

• oFF: The measuring instrument does not switch itself off automatically.6. Measuring 25

To rreset: Configuration mode is opened, RESET is lit. i Select the desired option with / and confirm with :

• no: Instrument is not reset.

• Yes: Instrument is reset. The instrument is reset to the factory settings. - The instrument returns to measurement view.

This chapter describes the steps that are required to perform measurements with the product.

Setting tthe mmaterial ccharacteristic ccurve: 1 Switch between the display of wood moisture (F) and building moisture (M): or press . 2 Select the desired option with or and confirm with : Display Category Example F 1 Softwood lumber Spruce, larch, cherry, pine, poplar, meranti F 2 Hardwood lumber Beech, oak, maple, ash, Douglas-fir, walnut, birchF 3 ChipboardM 1 Cement screedM 2 Anhydrite screedM 3 Concrete M 4 Solid brickM 5 High-insulating brickM 6 LimestoneM7 Gas concreteCAL Testing characteristic Not for on-site measurements!

Taking aa mmeasurement: The instrument is switched on and is in measurement view. i Hold instrument horizontal to contact surface. Slowly increase contact pressure to 1 to 3 kg until a stable value is shown In order to be able to evaluate a moisture course, several measurements at different positions or at different times are necessary. In drying processes, the displayed measurement values can in individual cases also be negative. This occurs as a result of the material composition and the different moisture gradients. When negative measurement values are displayed, the drying process is nearly finished, i.e., the more negative the values, the drier the material. For better assessment of the contact pressure, the instrument can initially be pressed against a scale.

Keep rreading, ddisplay mmaximum/minimum vvalue: The current reading can be recorded. The maximum and minimum values (since the instrument was last switched on) can be displayed. i Press several times until the desired value is displayed. - The following are displayed in turn:

• Hold: The recorded reading

7. Care and maintenance

This chapter describes the steps that help to maintain the functionality of the product and extend its operating life.

Cleaning tthe hhousing: i Clean the housing with a moist cloth (soap suds) if it is dirty. Do not use aggressive cleaning agents or solvents!

Changing tthe bbattery/rechargeable bbattery: The instrument is switched off. 1 To open the battery compartment on the rear of the instrument, push the lid of the battery compartment in the direction of the arrow and remove it. 2 Remove the spent battery/rechargeable battery and insert a new battery/rechargeable battery (9 V monobloc). Observe the polarity! 3 To close the battery compartment, replace the lid of the battery compartment in position and push it against the direction of the arrow.
