But it does not alter or distort the physiological signal in any way. You establish the baseline you want in the conventional manner. The CLC circuit remembers that baseline and each time the instrument is turned on you simply press the button to return the pen to the baseline you previously selected. If during the exam a pen reaches its excursion limit, simply press the CLC button and the pen will instantly and precisely return to its original baseline. New baselines can be established as required and pens can be re-centered manually if needed.
All baseline information is preserved along with response amplitude, character, and shape.
Except for more precise, quicker re-centering, the tracing for every parameter is identical to what it would be without the CLC circuit. In the unlikely event of a channel malfunction, the examination can be completed by switching to another channel. For example, if the channel being used to record cardio should be damaged or fail, one of the Pneumo channels can be switched to the Cardio function by merely turning a knob. One Allfunction channel is provided on all instruments having 3 or more electronic recording modules. The Advanced Technology Electronic Cardio provides the examiner maximum sensitivity and flexibility while simultaneously providing minimum subject discomfort and inconvenience.
