HANDLING
The meter can detect errors in either the test or the measurement modes. When in the measurement
mode, a blinking vertical bar will appear in the top left corner of the display indicating an error has
been detected. If the error reporting function is enabled, error messages will be displayed as separate
menu pages. The fi rst line of the error menu page indicates the total number of errors and the second
line displays the error message. Measurement mode error messages are listed below.
