As an alternative to detector current measurement, the Interface OCI400 with PC
software ACS410 can be used. In that case, the DC microammeter is not required.
Note!
QRB4 cable connection!
Connect the blue QRB4 cable to terminal 11.
Connect the black QRB4 cable to terminal 12.
Otherwise the QRB4 will not function.
