 CL bridge (capacitor tester) HP4278A 

 ★ measurement speed: 6.5ms/10ms/21ms ★ measurement parameters: CD, Q, ESR, G 
 ★ CD measurement accuracy: 0.07%, 0.0005 (1kHz, 21ms) 
 ★ 0.05%, 0.0002 (1MHz, 21ms) 

 Agilent 4278A 1kHz/1MHz capacitor tester is a reliable high-speed high-precision instrument 
 Used in the production line and quality control in the capacitor into the factory for inspection. Agilent 4278A can improve the small capacitor 
 Volume and efficiency of the test medium capacitor (measurable to 200μF, the capacity to accommodate the majority of ceramics and 
 Film capacitors of data values).
