"MULTI MODE" function

This programme is very useful for extending the time of sampling with the purpose of obtaining a more
representative environmental sample "in actual operating conditions" (very important, for example, during surgery).
The total air volume to be sampled is aspirated with two or more sub volume aspirations (e.g. 1000 litres in ten runs
of 100 litres at five minute intervals). Before entering the MULTI MODE programme you should, therefore, decide (a)
total volume of air to be sampled onto the contact plate; (b) number of runs; (c) interval time.
Switch on the unit by touching the screen for at least two seconds.
Press MENU and select MULTI MODE function by pressing the "UP" or "DOWN" arrows.
