5. On the PreAmp CBA, adjust R6 to 0 VDC ±.010 at J14
with reference to J16.
6. On the controller, press ZERO PRESS, and zero the pressure
for the appropriate pump.
7. Enter a set pressure (such as 5,000 psi) and run the pump
to that pressure. On the PreAmp CBA, adjust R27 until
the pressure gauge reads the set pressure.
8. Run the pump up to 10,000 psi, checking the pressure
gauge for accuracy. If the reading is not within ±25 psi,
readjust R27 to match the set pressure.
