The LCR400 is a low-cost precision LCR bridge intended for use within component inspection, laboratories and production facilities. The basic measurement accuracy is 0.1% and the maximum measurement frequency is 10kHz.
As well as remembering the last used set-up, the LCR400 incorporates non-volatile memory for up to nine complete instrument set-ups for rapid recall.
FEATURES
0.1% basic measurement accuracy.
Dual 5 digit high brightness displays.
Automatic component recognition.
Built-in 4 terminal component fixture.
Limits comparator with 8 Pass bins plus 2 Fail bins.
Three test frequencies, switchable bias.
