Frequently Asked Questions - 6062 Testo

How to turn the Testo 606-2 on and off?

To turn on, briefly press the ⏻ button. To turn off, hold the ⏻ button pressed for about 2 seconds until the display turns off.

How to change the batteries of the Testo 606-2?

Slide the battery compartment cover downwards, remove the used batteries, insert two new AAA (1.5 V) batteries observing polarity, then close the compartment.

What does the display 'Hi' or 'Lo' on the screen mean?

These messages indicate that the measured value is outside the measuring range (too high or too low). Ensure that the tested material has not undergone special drying or moistening.

How to test the functioning of the device?

Press the ⚠ button several times until 'Test:' is displayed, then connect the measuring electrodes to the contacts of the control resistor on the cap. If 'Test: ok' appears, the device is functioning correctly.

How to select the type of material to measure?

Press the ♠ button several times until the desired characteristic curve (wood or construction symbol and number) is displayed. Use the provided list to select the material.

How to use the Hold, Max and Min functions?

Press the Mode button several times to toggle between displays: current value, Hold (values are held), Max (maximum values), and Min (minimum values). Max/Min are only available for air humidity and temperature.

How to convert the displayed humidity percentage to water content?

The water content in % is calculated as: (wet weight - dry weight) / dry weight × 100. For example, for a wet weight of 180 g and dry weight of 150 g, the water content is 20%.

What are the measurement ranges for wood moisture?

Depending on the wood species, the range varies from 7.0% to 54.8% by mass. For example, for beech, spruce, or larch, the range is 8.8 to 54.8%.

How to clean the Testo 606-2 device?

Use a damp cloth (soapy water) to clean the housing. Do not use solvents or harsh cleaning agents.

What to do if the device does not display 'Test: ok' during the function test?

Clean the measuring electrodes and the contacts on the protective cap. If the problem persists, contact Testo customer service to have the device repaired.

Using the product

To guarantee correct readings:

- Repeat the measurement at several points. The differing resistance of the wood, with or across the grain, may have an impact on the measurement result. If the injection needles are inserted with the grain, this may result in slightly higher readings because the resistance in the material is lower.

- A measurement is only implemented as far as the depth that the injection needles are inserted within the material. Insert the measuring needles as far as possible (4 to 5 mm).

- When measuring fuel moisture content, it is advisable to split the log prior to measurement and to measure at three points. Measuring points: each 5 cm away from the left and right cut edge and once in the centre of the log.

- Keep temperature and humidity sources which may falsify the measurement (e.g. hands) away from the sensor.

The values displayed are highly dependent on the building material/manufacturer used, and on the ambient conditions. As the materials are natural, the same materials can vary from batch to batch.

Questions and answers

Question	Possible	causes/solutions
Hi or Lo	· Readings outside the measuring range (too high, too low): Readings outside the measuring range (too high, too low): for materials that have not been specially dried or moistened, the measurement results should always be within the measuring range.
	· Residual capacity <10 min: Change batteries.
Testing the instrument function: Test: ok does not light up · Clean sensing electrodes and contacts on the top of the protection cap. · If the error message appears again, send the instrument to Testo Customer Service.

The material's measured moisture content is relative to the dry weight (0% moisture) of the relevant material. The stored material characteristic curves were determined using the Darr (wet and dry weighing) method. The specified measuring ranges are derived from this.

Conversion to percent by weight

Percent by weight = (wet weight-dry weight) × 100 / dry weight

Example

Wet weight: 180 g

Dry weight: 150 g

Percent by weight: (180 - 150) × 100 / 150 = 20%

Conversion to water content

Water content \% = (wet weight-dry weight) / dry weight × 100

Example

Wet weight: 180 g

Dry weight: 150 g

Percent by weight: (180 - 150) / 150 × 100 = 16.6%

What constitutes dry, or at risk, or damp?

The values indicated serve as guideline figures for assessing the materials. The values are typical inner area values

Characteristic curve	Material Dry At risk Damp /		very damp
Characteristic curve 1 or 2 inside heated	Beech, fir, larch... < 12 12...15 > 15
Characteristic curve 1 or 2 inside unheated	Oak, pine, maple wood... < 15 15...20 > 20
Characteristic curve 3	Cement screed < 3 3.. 5 > 5
Characteristic curve 3	Concrete < 2.2 2.2...4.4 > 4.4
Characteristic curve 4	Anhydrite screed < 0.5 0.5...1 > 1
Characteristic curve 5	Cement mortar < 3 3...5 > 5
Characteristic curve 6	Lime mortar < 2 2...4 > 4
Characteristic curve 6	Gypsum < 2 2...4 > 4
Characteristic curve 7	Brick < 1 1...3 > 3

Guideline values for the installation moisture of wood, which sets in as an average after a certain period in use-status (DIN 1052-1 (4/88) Para. 4.2.1.):

Char. curve	Application area	Wood humidity in % by weight
1 or 2	buildings closed on all sides with heating	9 ± 3
1 or 2	buildings closed on all sides without heating	12 ± 3
