The light display on the panel illuminates only those controls associated with a different mode of operation. When the Function Program switch above is turned to one of four positions, the corresponding switch setting indicates the analytical mode, the variable held constant, and the measured variable. FEATURES •
Light display logic illuminates all controls, directs opeiator for each analytical mode. • Connects to any strip chart recorder with a sensitivity up to 100 millivolts full scale. •
Buffer amplifier (10-'- ohms) isolation permits operation of four electrodes in a common solution without drawing common currents.
•
AC operation over a range of 0-10 KHZ at low current (0-5 ma) and 0-1 KHZ at high current (0-1 A).
•
