Altek 830-KP manual Count Frequencies, Connection for signals with amplitudes to 250 V RMS

OPERATING INSTRUCTIONS

COUNT FREQUENCIES

Choose this function to use the 830-KP as a frequency counter. Available ranges are from 0.01 to 15.00 kHz, 1 to 1500 Hz and from 1 to 1500 CPM (Counts-Per-Minute).

To measure waveforms with amplitudes between 1 V and 10.25 V RMS use the low level inputs. Use the high voltage connection to read waveforms with amplitudes from 10.25 to 250.0 V RMS

1)Disconnect one or both input wires from the device to be calibrated

2)Press the FREQUENCY/PRESSURE pushbutton until any frequency signal (KHz, Hz or CPM) appears on the display.

3)Press the DISPLAY/SOURCE/READ push-button until READ and KHz, Hz or CPM appear on the display

4)Press the TYPE/ENG UNITS push-button to select between KHz, Hz or CPM on the display

5)Connect the red READ lead of the calibrator to the plus (+) input of the device and the black READ lead to the minus (-)
