When current is present on the LE and HE Slit current meters you may then switch the Control Mode to AUTO (middle position) and the SLIT control light should illuminate. If there is instability in slit control you may try raising the CONTROL GAIN more. If the slit currents are not balanced when in slit control, make slight adjustments in the CHARGING VOLTAGE to balance the slit currents. |
