2-6 Turning On the MS2090A Field Master Pro
The Anritsu MS2090A Field Master Pro is capable of approximately two hours of continuous operation from a
fully charged, field-replaceable battery (refer to “Battery Information” on page 2-8). The instrument can also be
operated from a 15 VDC source (which will simultaneously charge the battery). This can be achieved with
either the Anritsu AC-DC adapter or the automotive power adapter, which can be purchased as an optional
accessory. Refer to the instrument Technical Data Sheet for more options and accessories.
To turn on the Field Master Pro, briefly touch the power button on the lower right of the touchscreen (see
Figure 2-1 on page 2-2).
The Field Master Pro takes approximately 60 seconds to complete power-up and to load the instrument
software. At the completion of this process, the instrument is ready for use.
Power/Charge LED Indicators
The power/charge LED is integrated with the power button. The LED has the following indicators:
• Solid white when the instrument is on or booting up.
• Slowly blinks orange when the instrument is off and connected to an external power source, and the
battery is charging.
• Solid green when the instrument is off and connected to an external power source, and the battery is
fully charged.
• Solid red when the instrument is off and connected to an external power source, and the battery is NOT
installed or has a fault.
Shutting Down and Restarting
To shut down or restart the instrument, briefly touch the power button (a shutdown dialog will be displayed),
then select RESTART INSTRUMENT or POWER OFF. The current setup is saved when the instrument is
shut down or is restarted. Once the instrument shuts down, it will either power off completely (if running on
batteries) or it will go into a low power state (if running on external power).
Caution
When using the Automotive Power Adapter, always verify that the supply is rated for a minimum of
75 watts @ 15 VDC, and that the socket is clear of any dirt or debris. If the adapter plug becomes hot
to the touch during operation, discontinue use immediately.
Note
Keep the fan inlet and exhaust ports clear of obstructions at all times for proper ventilation and
cooling of the instrument.
