The PIE 541 Frequency Calibrator with integral totalizer offers an accuracy of ± 0.005% of range and can be used for devices with frequencies from 1 cycle/hour to 20,000 kHz. It can read a wide range of signal frequencies and waveforms from 50 mV to 120V peak from sources such as flow-meters, and velocity and motion detectors. As a waveform source, the output can be specified as a sine or square-wave with amplitudes from 100 mV to 12 Vp-p. It also functions as a totalizer for inputs or outputs from 1 to 99999 in 1.0 to 100.0 minutes. The PIECAL 541 has a gate-time LED which flashes with received pulses, indicating when the proper input adjustment level has been met. When calibrating a totalizer, the PIE 541 eliminates the need for a stop watch since it automatically stops when the preselected number of pulses has been sent to the totalizer.
