With the purchase of this appliance you have acquired a precision measuring instrument. Although the hot-wire anemometer is an extremely complex and sensitive measuring instrument, its sturdy construc­tion means that you will be able to perform precise measurements for many years if it is used properly. Please read the following information and instructions carefully and ensure that this manual is always kept near to your measuring instrument.
m Please read this manual carefully before using
the appliance for the first time. It contains im­ portant safety instructions. Moving the appli­ ance from a cold to a warm environment (and vice versa) can lead to the formation of conden­ sation on the measuring circuitry of the ap­ pliance. This physical effect, which cannot be prevented by structural means for any measuring instrument, leads to false measure­ ment values. Depending on the temperature difference, the appliance requires an ‚accli­ matisation time‘ of approx. 15 - 30 minutes be-
fore the measuring procedure can be resumed.
01. Features
Thermal air speed meter
The measuring instrument is capable of measuring very low speeds - lower than the so called calm (~1.85 km/h); however, it can also measure speeds designated as storms (approx. 90 km/h). (Refer also to the general comparative table of wind velocities)
1.1 Comparative table of wind velocities
< 1,85 km/h Calm < 9 km/h Light breeze < 19 km/h Gentle breeze < 28 km/h Moderate breeze
< 37 km/h Fresh breeze < 46 km/h Strong breeze < 56 km/h High wind < 65 km/h Near gale < 74 km/h Gale < 83 km/h Strong gale < 93 km/h Storm
1.2 Features
• Extra-slim probe, ideal for gratings and diffusers
• Combination consisting of hot-wire and standard thermistor for fast and precise measurements even at low air speeds
• Maximum and minimum values with recall function for recalling a certain value.
• Microprocessor circuit provides for the highest possible degree of accuracy with special functions and features
• Very large, easily readable LCD with dual display
- air speed and temperature can be read off simul­ taneously

• Power is supplied by a 9V battery
• Compact, light construction - the measuring in­ strument displays precise measurements as digital values.
• Measurements with different units of measurement:
- Temperature: °C, °F
- Air speed: m/s, km/h, ft/min, mph, knots
- Volumetric flow rates ft³/min [CFM (cubic feet per minute)] and m³/min [CMM (cubic metres per mi­ nute)] are possible.
• Built-in thermistor for temperature measurements
• Long-life components in a sturdy, light ABS housing
• Hard-shell carrying case
• Application possibilities (e.g.): Environmental analyses, air conveyors, deflectors, cleanroom systems, air- speed measurements, air balance, fans/motors/blo­ wers, kiln speeds, cold rooms, paint spray booths, leak measurements on windows, doors, etc.

You can change the unit of the measured value, e.g. °C or °F, when calculating the temperature by pressing the Unit Arrow button. After the necessary number
of measured values has been obtained, press the (Mean) button; „Mean“ now begins to flash and the
calculated value is displayed. Press the (Mean) button again to resume the measuring procedure.
Performing a mean value calculation over time
Press the mean button for approx. 2 sec. „Mean“ appears and you are now in the mode for calculating a mean value over a period of time. The time display (in mm.ss) necessary for this is located in the upper half of the display. The measuring procedure begins as described above in Multi-point mean value calcu­lation with the air speed. To initiate the calculation for temperature or volumetric flow, please press the Flow/Temp button .
As soon as measurement begins, i.e. as soon as the air speed sensor has been prepared for use (push the sensor head cover downwards and set the marking against the wind direction), the time measurement is started by pressing the (Enter) button, thus initia­ting the calculation of the mean value.
You can change the unit of the measured value, e.g. °C or °F, when calculating the temperature by pres­sing the Unit Arrow button. After the required peri­od of time (you can interrupt and resume the measu­rement procedure several times by pressing the
(Enter) button, press the (Mean) button; „Mean“ starts to flash and the calculated mean value is dis-
played. Press the (Mean) button again to resume the measuring procedure.
Hold-Zero (freeze) function / freezing the measured values on the display
Press (Hold/Zero) to freeze the values on the dis­play. The word „HOLD“ appears.
Press (Flow/Temp) to switch between the tempe­rature display and the display for the air speed and
the calculated volumetric flow rate. Press (Hold/ Zero) to release the value again.
Displaying the Max/Min values (maximum/minimum value). Press (Max/Min) to switch from MAX (maxi-
mum value) to MIN (minimum value).
Battery replacement
Switch the appliance off. Remove the cover on the back of the appliance. To do this, gently press the de­pression provided towards your body until the cover is released, then push the cover approx. 1 cm to the rear while holding it at the side between thumb and forefinger/middle finger and lift the cover off the bat­tery compartment. Insert a new 9V battery. Replace the cover on the compartment. To do this, follow the procedure described above in the reverse order. The appliance is now ready for operation once more.
07. Appliance probe
The probe of your hot-wire anemometer is a precise measuring component and is very sensitive to dama­ge. Therefore always protect the probe after comple­tion of the measuring procedure by sliding the cover upwards. This precautionary measure also guaran­tees a respectable measurement if you want to begin a new measuring procedure and have to set the zero. The telescopic probe can be extended to a length of approx. 1 m. You can therefore set the desired length as described in item 6.
If you wish to make the probe smaller again, do not do this by pushing the telescopic rod together, but by pulling on the probe cable di­rectly underneath the probe grip, where the sensor cable is fed out, and in this way collap­sing the probe like a telescope. Otherwise, the telescopic probe cannot be collapsed properly or the sensor cable may be destroyed when doing so.
