Page 9: Calibration Procedure
ANALOG OUTPUT ADJUSTMENTS (PCA-121): 20mA ADJ A twenty turn adjustment which is used to set current output to the desired span corresponding to the equivalent full scale range. (i.e. 20 mA at 100 RPM). 4mA ADJ A twenty-turn adjustment that is used to set the current output signal to the desired zero value. - Page 10 FOR CURRENT OUTPUT: • Connect a digital milliampmeter or equivalent, across the current output terminals. • On the PCA-121 select the “Coarse Range Adj” that corresponds to the maximum input frequency. Refer to Table - 1 for selection options. • Adjust “4mA ADJ”...
