Capillary, phosphor, and dynode voltages all read near zero kilovolts when in Operate using Xevo TQD and Xevo TQ-S micro- WKB272201

Article number: 272201

SYMPTOMS

Capillary voltage readback is 0.9 kV for a setting of 3 kV
Gases are on and system is in Operate
Rebooting the EPC does not resolve
FOUND: phosphor and dynode voltages read back 0.2 kV on the diagnostic tab of the tune page

Unknown electronics glitch

Put the Xevo TQ-S micro in Standby
From the MS tune page, vent the Xevo TQ-S micro (Vacuum > Vent).
When the vacuum system stops, close MassLynx, power-off the Xevo TQ-S micro, and disconnect the power cord from the back of the instrument.
Leave system off for about 1 minute.
Plug the power cable back in and power-on the Xevo TQ-S micro. Wait for the instrument to initialize (takes about 2 to 3 minutes).
Open MassLynx. Verify communications via the Not Scanning MS status at the bottom of the sample list page.
Open the Tune page and start the vacuum system (Vacuum > Pump).
When turbo speed reaches 100%, turn on the API and Col gases and put the system into Operate.
Verify that capillary, phosphor, and dynode voltages now read back their expected values.

Reseating the connections of dynode and capillary while powered-off could help.
