3. Data Specifications of ODAR
a) Resolution of ADC-16 bit For TC ADC using 19 bits & for remaining Sensors 16 bits ADC
b) Three ways to start Logging: I. Remotely controlled through wireless
I. Manually pressing a button on the unit II. Short to open trigger input will start the recording
II. Remotely controlled through wireless
III. Short to open trigger input will start the recording
