Notice the Running Icon on the screen and monitor the red, yellow, green ‘traffic
light’ status indicators around the Start/Pause pushbutton while you are measuring. The
indications should be as follows:
• Yellow status indicator flashing every 5 s before you start the measurement
• Steady green status indicator after you have pressed the Start/Pause pushbutton
and during the measurement (if everything is OK)
• Yellow status indicator flashing every 5 s when you have stopped, saved the measure-
ment and are ready to do another measurement
• Yellow status indicator flashing slowly, 0.5 s on, 0.5 s off, if you pause the measurement
• Red status indicator flashing rapidly if you encounter an overload condition during the
measurement

control the measurement. The status field at the top of the screen will give short textual
feedback on the pushbutton operation. A visual indication of measurement status is also
displayed on the status line, by way of the
Stopped icon , the Running icon and
the Paused icon . See Fig.3.4.
