Modes UT ONE is designed to provide the user with greatest possible flexibility so it provides four different measurement modes for measurement on three main channels Note that only one measurement mode can be active at any given time Also some measurement modes can only be activated using the remote communication interface and computer software Ambient channels are continuously acquired in the background independently of the measurement mode of main channels TI channel is acquired only in combination with an acquisition of a main channel so its refresh rate is not guaranteed 6 1 Continuous measurement mode Continuous measurement mode is the basic measurement mode which supports the operation via user interface and remote communication interface User must first configure the channels using the 1 Main Channels Configuration window or equivalent remote communication interface commands Note that you may enable any number of main channels including none The acquisition starts after you touch the green START button in the measurement window Channels are acquired sequentially from the lowest channel index to the highest channel index Disabled channels are skipped without any additional delay If all main channels are disabled only ambient channels are acquired at 4 second acquisition rate Measurement result in continuous measurement mode is assembled after the last main channel in acquisition sequence is completed Current values of
