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. (i.e. 4mA at zero RPM).
V
FS
ADJ
A twenty-turn adjustment that is used to set the voltage output to the
desired span corresponding to the equivalent full scale range. (i.e.
5VDC or 10 VDC at 100 RPM).
V
O
ADJ
A twenty-turn adjustment that is used to set the voltage output signal
to the desired zero value. (i.e. 0 VDC at zero RPM).
COARSE RANGE ADJ
A dual in line DIP switch which is located on the PCA-121 board,
which is used to perform a coarse range adjustment for the input
frequency range.
V
FS
SELECTION
A two position jumper (JP1) that is used to select the desired voltage
output range of either 0 to 5VDC or 0 to 10VDC.
