About Error Messages
If an error occurs during Sweep operation, an error message will appear at the top right. In this
case, ER1 indicates that the frequency of interest could not be set.
Frequently, very strong local RF fields can cause erratic meter operation and/or incorrect SWR
readings. Try to eliminate the strong RF fields and try again.
If ER1 appears even with no antenna connected, there may be an internal malfunction in
the meter. Contact your dealer for repair assistance.
