At switch-on of the instrument, it shows an information box within some seconds. Where it shows which model of Swema 3000 it is, which software version (Firmware) the instrument has as well as the battery voltage (less than 2.0V the instrument wil shut down itself). If you have a sensor con- nected, you will also see which type of sensor it is when the calibration comes out as well as the serie number on the probe (does not apply relative humidity/temp sensor). - Page 6 Modes: Swema 3000 helps you to calculate and work in the correct way when you use the different mo- des. The differemt sensors that exists to Swema 3000 have sometimes their own modes, e.g. for the differencial pressure sensor the measurement mode DPF (Differencial Pressure air Flow).

Auto Zero ON with SWA 10 or Swema 3000md/mdH+ SWA 10 and Swema 3000md has an inbuilt zero valve. Auto Zero is set to ON by default. By the built in valve the zero pressure point is automatically checked every time you take a measurement by pressing ”ENTER”. - Page 11 Possible measuring modes: AP, AS and LOG. Radio/BlueTooth modem for balancing of ventilation SwemaTwin transfers measured values on the reference valve from one Swema 3000 to another through radio/BlueTooth modem or 40 meter cable. The flow relation between them is displayed, which makes adjustment according to the proportional method an easy task for just one person.

Insert k- factor, and the Swema 3000 calculates the air flow according to the formula: q = k sqrt(∆P). The specific k-factor is supplied by the manufacturer of (exhaust and supply) ventilation valves. -
Page 13: Ap (Average Point)
When measuring, collect values with the enter button. When values are collected the display will show average-, maximum-, minimum-values and number of measure- ments. Swema AB Pepparvägen 27 SE-123 56 FARSTA 13 Tel: 08 94 00 90 Fax: 08 93 44 93 swema@swema.se... -
Page 14: Apf (Average Point Flow) - Air Flow In Chanel And With Area
Measuring with APF (Average Point air Flow) Possible probes are: SWA 31, SWA 31E or SWA 07 or SWA 10 with pito static pipe or Swema 3000md. Use the APF mode for measuring the flow in ducts. Swema 3000 calculates the flow in l/s or m /h by multiplying the air velocity with the duct area. - Page 15 Measuring When all parameters are installed, press EXIT to come back to mode. Swema 3000 shows choosen Ø, HxW or Area on the bottom of the display. At calculation with pressure sensor (PST) pressure and flow are shown.

Page 16: Dpf (Differential Pressure Air Flow) - Air Flow With K-Factor
DPF is used to measure flows over diffusers and orifice plates with the decompression method. Then the diffuser’s K-factor is being used and you put it in the Swema 3000 to give a flow directly to the display. Swema 3000 calculates the flow accor- ding to the formula: q = k • √∆P... -

Page 18: Af (Average Flow) - Air Flow With Spigot
Measuring When all parameters are installed press EXIT to come to mode. Collect measure values with ENTER or the button on Swema- Flow 125/2000. When the measure values are collected does Swema 3000 show mean-, max-, min-value and standard deviation. When all measure values are collected, you can choose if you would like to save or delete the measure. -
Page 19: Bp (Back Pressure) -Air Flow With Compensated Spigot
SwemaFlow 125/D can do this correction for you. By mea- suring 2 times with and without throttle ring, Swema 3000 calculates the flow witout restricor i.e. the flow from the diffu- ser without probe. - Page 20 After PO 2 is measured will Swema 3000 calculate the actual value. On the display it says True, Max and Min. Max without throttle ring and Min is with throttle ring and True is the actual value.. Choose if you would like to save your measurement. To delete, press CLEAR.

Page 22: Asf (Auto Sampling Air Flow) - Sampling With Calculating Air Flow
Sampling with air flow calculation ASF is available with hot wire anemometers. Like AS, but Swema 3000 calculates the flow in l/s or m Enter the area as height x width or as area directly. In mode ASF does Swema 3000 calculate the area without channel reduction (K2-reduction) because it is not made for cannel measurement. - Page 23 By slowly sweeping (traversing) the sensor above the surface. e.g. an intake grille or the opening to a fume, you measure the total flow. Repeat the measurement until you get the same measure values so that you learn the technique. Swema AB Pepparvägen 27 SE-123 56 FARSTA...

Saving of measure values (APF & DPF) If Swema 3000 with built-in barometer and thermo coupple (Swema 3000d & Swema 3000md) is used will the values in mean, max & min be calculated correspondent for what the temperature and the barometer were at every single measure point. -
Page 31: Technical Data
The uncertainty of measurement for each probe is stated below as the uncertainty for the probe to- gether with a calibrated Swema 3000. The uncertainty is stated with coverage probability of 95%. Included in the uncertainty for each probe is the uncertainty for Swema 3000, interchangeablity, calibration, temperature dependence, hysteresis and repeatability. -

So, for Ø 100 → 100Pa corresponds 50 l/s Use the connection above for k: k= 50/10 → 5,0 In this case the k-factor was 5.0. Set k=5,0 in Swema 3000 then you will get the flow directly in l/s, m /h or CFM. -
