Test, calibrate and diagnose an expanse of frequency devices efficiently with the PIECAL 541 Frequency Calibrator with Totalizer from Practical Instrument Electronics.
Equipped with the standard functions of a frequency calibrator, the PIECAL 541 hosts a range of innovative additional features. Trigger level adjustment can be quickly and easily executed with the LED indicator which shows gate time. Users can test limits with the dual action EZ-Check switch or make adjustments with the EZ-Dial test knob.
The 541 calibrator eradicates the necessity of a stopwatch as the calibrator automatically stops once the chosen number of pulses has been sent to the totalizer, saving both time and effort in a variety of applications.
