The 541 is designed for calibration, testing and diagnosing turbine meters, frequency counters, vibration systems, tachometers, vortex shedders, integrators and any frequency device. Save hours of time compared to other calibration methods. When calibrating a totalizer, the 541 eliminates the need of a stop watch. Set the number of pulses and number of minutes required and it automatically stops when the selected number of pulses has been sent to the totalizer. The 541 has a handy LED indicator showing gate time for easy trigger level adjustment. The LED also pulses with the frequency output for calibration of optical pickups.

The 541 has 5 ranges from 1 CPH to 20.000KHz for source and read. Totalizer inputs/outputs are from 1 to 99999 pulses in 1.0 to 100 minutes, and read a wide range of frequencies and wave forms from 50 mV to 120V. The 541 can source sine and square waves with zero based or zero crossing and has an adjustable output amplitude from 100 mV to 12 V peak-to-peak.
