1163   Error: Current of Ion gauge is out of range (Standby -> Analysis).

There is no flow of emission current. The Ion gauge driver of the Connection PCA monitors the current, and the Main PCA determines the current (When the instrument is changing from Standby mode to Analysis Mode).

This error is displayed at more than 8mA or less than 3µA during regular operation and at 280µA or at 120µA or lower during high-sensitivity operation.

The following are the probable causes.
