PIECAL 541 Frequency Process Calibrator with Totalizer function

Accuracy: ± 0.005% of range 5 ranges from 1 CPH (Count-Per-Hour) to 20.000 KHz for source and read Totalize inputs/outputs from 1 to 99999 pulses in 1.0 to 100.0 minutes. Read a wide range of frequencies and waveforms from 50 mV to 120V peak. Source sine and square waves with zero based or zero crossing waveforms. Adjustable output amplitude from 100 mV to 12 V peak-to-peak. Gate trigger LED flashes in synch with the output frequency to calibrate optical pickups. This also allows easy adjustment of the attenuation for proper gate triggering. EZ-Dial™ knob easily adjusts output by 1; press down and while turning the knob for a faster dialing speed EZ-Check™ switch for instant 0% and 100% span adjustments Store new EZ-Check™ values by pressing the EZ-Dial™ knob Uses a standard 9V Alkaline battery with easy access to the battery compartment Superior battery life of 45 hours under typical continuous usage Small, tough and protected to 60V Carrying case included and optional Test Data available NIST Traceable Calibration Certificate included
