record up to 200 channels(DAS240) or 10 channels (DAS220), voltages (from 1mV to 100V), currents, temperatures (thermocouple, Pt100, Pt1000), resistance etc… as well as logical channels. The dialog between the user and the recorder is made easier thanks to an intuitive interface on a wide capacitive and color 10’’1 touchscreen. The measurement parameters are easy to program. The recording is made directly on an internal 32 GB memory card. The DAS240 is composed wi ...

They are used by: - the « setup » menu, with the A and B alarms - the « triggers » menu, with the start and stop parameters of the recording.  Edge/Level trigger  Edge trigger: you need a change of status o Example: Channel A1, rising edge, threshold = 0V: triggers only if the signal status changes from negative to positive  Level trigger: no need to pass the threshold o Example: Channel A1, high level, threshold = 0V: triggers only if the signal is positive  Alarms only have level triggers.  ...

By pressing the menu « channels », you access the table of all available analogic and temperature channels of your recorder. This table gives you a quick insight of the various adjustments of the channels. You can change these adjustments directly in this table by pressing the parameter you want to update. You can display 10 channels maximum. or keys : to display other channels You can access the setting of parameters channel by channel by pressing the name of the channel at the top of the table (A1, A2…) or by pressing on the bargraph of the channel (right si ...
