Finder mk2 has two measuring modes The so called validation mode and the adjustment mode In the options menu one of these modes can be set as default At start up the FF mk2 will be ready to measure in the default mode The measuring mode can be recognized by the red blinking 0 adjustment mode or the validation mode In validation mode the FF mk2 a measurement starts by pushing the red button behind the left knob The FF mk2 decides when the measurement is ready normally within 10 to 15 seconds It will display the measurement result which then can be stored by touching store In adjustment mode the FF mk2 a measurement starts by pushing the red button The blinking number turns green and will change depending on the air flow volume The measurement will only stop after the red button is pushed again This way you can adjust the diffuser or valve to the desired air flow You may take down the FF mk2 to adjust the valve Wait long enough until a more or less stable reading is reached also after placing the FF mk2 back again Always stop and start again when going from one measuring location to another The measuring result can t be stored Switching between modes push the return button in the right upper corner Then you can select either validate or adjust To change the default mode you have to go to the options menu To do a measurement hold the FlowFinder mk2 by the left
