Auto-Setup button
Initiates the Automatic-Setup, which optimizes the PMT gains and
source lamp currents. This function combines automatic signal adjust-
ment with manual jumper positioning. The Auto-Setup process takes
approximately three minutes. Always perform an Auto-Setup after
any lamps, optical filters, or PMTs have been replaced.
When this button is clicked, a pop-up message is displayed asking
“Would you like to proceed with the Bench Auto Setup?”. This mes-
sage also lists conditions that need to be met before proceeding. If the
conditions have been met and you wish to proceed with the Auto-
Setup, click
Yes . If not, click No .
After a successful Auto-Setup, the PMT Level should be 7200–7400
mV, while the PMT Balance should be 2000–8000 mV. If these values
are outside these ranges, see “PMT Level and PMT Balance” in Chap-
ter 6.
Cancel Auto-Setup button
Stops the Automatic-Setup.
