Frequency calibrator 942

with totalizer

The 942 series is a frequency calibrator with totalizer, manufactured by ALTEK Industries Corp. This product features a handheld calibrator with the accuracy of an 8-digit counter. This can operate with ±0.001% of setting (10 PPM) laboratory accurate, 1 to 20,000 counts per hour, 0.1 to 2000.0 counts-per-minute (CPM), 0.01 to 999.99Hz, 0.001 to 99.999kHz and 0.01 to 250.00kHz six world ranges. To identify totalizer readings, this can output an exact number of pulses over 1 to 99mins. Its calibrator stops automatically outputting after selected the number of pulses has been transferred to the totalizer. This use as a timed totalizer for checking flowmeter and integrator outputs. For direct display extremely slow signals, removing waiting with stop watch and calculator, the CPH and CPM ranges are used. Its amplitude can be adjusted from 50mV to 12V p-p.
