We scanned ZM4/5 PSAMS with hot OM2. The 200V/200V of ZM4/5 PSAMS is already optimal value as shown in the attached figure. To optimize the PSAMS, we turned on ADF at 1.3kHz and monitored the ADF OMC trans. 

Before changing the PSAMS, we changed squeezing angle to make sure that the ADF OMC trans is minimized with original squeezing angle. For any PSAMS change from 200V, the ADF OMC trans only got worse so we did not change the squeezing angle after the PSAMS change and concluded that the 200V/200V of PSAMS is already optimal.
