Introduction

This chapter contains information about the power meter’s error

messages. It explains how to read the power meter’s error queue and lists

all of the power meter’s error messages and their probable causes.

When there is a hardware related problem, for example, a power sensor

overload, the error message is displayed on the status line at the top of the

display. In addition, the errors are also written to the error queue. If there

are any errors in the error queue the front panel error annunciator is

displayed as shown in Figure 4-1.

Other errors can also be generated when the power meter is being

operated over the remote interface. These errors also display the error

annunciator and are written to the error queue.
