The AH 2550A offers unparalleled stability, resolution and accuracy in a capacitance/loss bridge (whether manual or automatic). Its numerous state of the art features make it an exceptionally user-friendly instrument, just as was its predecessor, the AH2500A. The precision and ease of use of the AH2550A are creating new applications in science, calibration, and production in a wide range of fields.
Patented, digital phase-shifting circuitry needs no calibration and is temperature independent.
Enhanced test diagnostics are better able to isolate component failures and require less intervention by the operator.
Line-related noise rejection has been made even better.
Complete re-design of the digital circuitry provides very high reliability.
Upper limit of test signal voltage has a minimum setting of 0.3 mV versus 0.5 mV previously.
Largest measurable capacitance is now 1.5 µF versus 1.2 µF previously.
A real-time clock has been added.
The serial interface is compatible with the IEEE-1174 Standard.
The front panel display is fully alphanumeric.
The number of LED indicators on the front panel has been increased from 8 to 10.
