Problem: Dynamic measurement for industry Solution: CEC's 5-124 Portable Oscillograph Today, most progressive industrial lab­oratories—from aircraft and appliances to pharmaceuticals and plastics — are concerned with dynamic measurement problems. Somewhere along the line, some precise measurement must be made in designing, testing or manufac­turing. And, ideally, the procedure should be simple enough to eliminate the need for trained personnel. As a result, CEC's direct print 5-124 Portable Oscillograph has become the logical answer. Far more accurate and rapid than pen recorders, and notably superior to other instruments of its type, the modestly-priced 5-124 is made to order for virtually every application. Compare these advantages of the 5-124: • It records ·οη 18 channels—with no chemical processing required. • Dynamic or static data from d-c to 5000 cps can be recorded with standard CEC 7-300 High Performance Galva­nometers. • Writing speeds up to 50,000 ips are achieved on 7-inch-wide records —with automatically exposed grid line system and trace interruption.

• Five record speeds are provided (%., 1, 4, 16 and 64 ips) , each instantly selected by pushbutton. • No record magazine is required, elim­inating paper threading, • Easy access by removing a single cover. • It measures a mere 7% , /xl3 / /x-15% / / ; weighs only 40 lbs. • No special ly t ra ined personne l requ i red . A complete line of proven optional accessories is available for the 5-124. This line includes: 5-061-2 DATAFLASH TAKEUP ACCESSORY CEC's DATAFLASH produces visible data up to 60 times faster than other methods. Permits immediate readout of records at speeds up to four inches-per-second at frequencies from d-c to 5,000 cps. Adaptable to any CEC 5-124 Oscil­lograph. 1-163 D-C AMPLIFIER ACCESSORY CEC's 1-163 is a solid-state, low gain, wideband d-c power amplifier specifi­

cally designed to drive high frequency light beam galvanometers. Will deflect all CEC galvanometers to full scale rated deflection, and can properly damp and drive any other currently available re­cording galvanometer.
