Introduction

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.
