SET HOLD MODEMODE TEMP/%RH UNIT ANEMO LUX

This product is an all-in-one measuring device that allows you to measure all the key quantities associated with environmental measurements in the Ö eld of building physics. Within surveying applications, it can be used to measure the following: Ambient temperature (climate, building moisture), relative humidity (climate, building moisture), wind speed/air × ow (climate, ventilation, heating), illuminance (illumination), sound pressure level (noise). Consequently, you can use it to determine and assess the impact that general environmental conditions are likely to have on human physiology. Function/Application

When you switch the device on, it shows the current ambient temperature in °C on the display. To display the value in °F, press the „Unit“ button. By pressing the „Mode“ button, you can get the device to display the highest (MAX), lowest (MIN), average (AVG) or difference value (DIF) in addition to the current measured value. As its name suggests, the „HOLD“ button enables you to hold the current measured value. Ambient temperature

When you switch the device on, the „AUTO OFF FUNCTION“ is activated automatically. After 20 minutes, the device switches off automatically unless one of the buttons is pressed. To activate or deactivate the device‘s „AUTO OFF FUNCTION“, press the „SET“ button while pressing and holding down the „ON/OFF“ button. For optimum measurements, please wait approximately 15 minutes after switching on the measu- ring device so that it has time to adapt to the new ambient conditions in a particular room. Relative humidity may be deÖ ned as the ratio between the air‘s current water vapour content and the maximum that it can contain at the same temperature and constant pressure. Hot air can hold more water vapour than cold air. At 100% relative humidity, the saturation point has been reached and the air cannot hold any more water vapour. Press the „Temp/%rH“ until a measured value in % relative humidity (%RH) appears on the display. By pressing the „Mode“ button, you can get the device to display the highest (MAX), lowest (MIN), average (AVG) or difference value (DIF) in addition to the current measured value. As its name suggests, the „HOLD“ button enables you to hold the current measured value. Relative humidity

Activated Deactivated In the event of rapid temperature × uctuations (± 1°C), the sensor needs to adapt to the new condi- tions. Consequently, it takes a certain amount of time for a stable value to be established.

In the event of rapid × uctuations in relative humidity (± 1%), the sensor needs to adapt to the new conditions. Consequently, it takes a certain amount of time for a stable value to be established.

Display illumination If visibility is poor, switch on the display illumination. In order to pre- serve the batteries, the illumination switches off automatically after 10 seconds. To reactivate it, simply press the button again. HOLD MODEMODE

UNIT ANEMO LUX SET HOLD MODEMODE TEMP/%RH UNIT ANEMO LUX Manual_MultiTest-Master_GB.indd 09 27.09.2010 16:11:39 UhrA photoelectric sensor is used to measure the incident light intensity. This is the power of the radiated light per unit of area. Photometry deÖ nes light in terms of how it is perceived by the human eye. The sensitivity of the eye also depends on the wavelength or light colour. The measuring unit uses special colour Ö lters on the sensor that adapt to the sensitivity curve (CIE curve). After switching on the device, press the „Lux“ button. Please observe the following application notices when determining illuminance: – Align the sensor on the measuring surface so it is perpendicular to the light source – During measurement, the incidence of light must not be affected by shadows from the operator or other objects not involved in the measurement – Remove the wind de× ector from the microphone – You can check the measuring device‘s zero position by covering the sensor completely. – Discharge, × uorescent or energy-saving lamps should be switched on well in advance of the measurement process (approximately 15 minutes) so that the brightness has time to stabilise By pressing the „Mode“ button, you can get the device to display the highest (MAX), lowest (MIN), average (AVG) or difference value (DIF) in addition to the current measured value. As its name suggests, the „HOLD“ button enables you to hold the current measured value. Illuminance (lux)

SET HOLD MODEMODE TEMP/%RH UNIT ANEMO LUX The device measures radiation in the main direction, perpendicular to the sensor plane. Incident light rays at an angle are taken into account by the sensor using an adjustment curve.

In the event of a high incidence of light, the measured value on the display is reduced by a factor of 10 or a factor of 100. SET HOLD MODEMODE

The integrated microphone receives the incoming sound waves and converts them into electrical signals. Human hearing involves speciÖ c auditory curves. The greater the sound pressure, the louder the sound is perceived to be. The higher the frequency, the higher the pitch of the sound is perceived to be. To ensure that measurements are aurally compensated, this measuring device is Ö tted with Ö lters. The A-weighting (dB A) replicates the frequency response associated with human hearing and is used for the majority of industrial noise and environmental noise measurements. The C-weighting is used in the case of scientiÖ c measurements, for example. After switching on the device, press the „dB“ button. To switch between dB (A) and dB (C), press the „Unit“ button. Point the microphone towards the relevant sound source and observe the relevant distance. By pressing the „Mode“ button, you can get the device to display the highest (MAX), lowest (MIN), average (AVG) or difference value (DIF) in addition to the current measured value. As its name suggests, the „HOLD“ button enables you to hold the current measured value. Sound pressure level (dB)

SET HOLDMODEMODE TEMP/%RH UNIT ANEMO LUX Powerful wind noises (> 10m/s) can affect the measured value. In such cases, you should use the wind de× ector supplied with the product.

Manual_MultiTest-Master_GB.indd 11 27.09.2010 16:11:41 UhrThe measuring device is capable of measuring wind speed or air × ow with the built-in fan wheel. The resulting measurements can be output in various units. On the basis of these quantities, it is also possible to measure volumetric × ow. After switching on the device, press the „Anemo“ button. Press the „Unit“ button repeatedly to change the units: FPM (feet per minute), knots, m/s (metres per second) and km/h (kilometres per hour). Press the „Anemo“ button again if you want to determine the volumetric × ow. Use the „Unit“ button to switch between the units CMM (cubic metres per minute) and CFM (cubic feet per minute). Firstly, measure the × ow opening area. Then you can set the measured area by pres- sing the „Set“ button and making the necessary adjustments with the „Unit“ (change position of decimal point), „Hold“ (+) and „Illuminati- on“ (-) buttons. Press the „Set“ button to conÖ rm your entry. Please observe the following application notices when deter- mining wind speed/air ƃ ow: – Avoid direct sunlight during the measurement process – Place the device as close as possible to the source of the air × ow – Position the device parallel to the source of the air × ow – Use the MAX function to determine the point where the air × ow is greatest By pressing the „Mode“ button, you can get the device to display the highest (MAX), lowest (MIN), average (AVG) or difference value (DIF) in addition to the current measured value. As its name sug- gests, the „HOLD“ button enables you to hold the current measured value. Wind speed/Air ƃ ow
