Getting started
(Applying power and selecting test modes)
The power ON-OFF switch, located on the front of the Service Monitor, will power up the Service
Monitor from either an AC or DC supply.
With a power source connected, switching on the Service Monitor will cause the cooling fan to
operate and one of the test mode menus to be displayed. Which screen is displayed will depend on
which store is selected as the 'Power Up From' store on setup page 2. See Setup page 2 on page
3-13.
The
BAT warning is activated when the voltage at the DC terminals falls to approximately 11 volts.
If you are unfamiliar with the Service Monitor, a few minutes spent exploring the setup menus and
test modes is helpful.
The following explanation of keys and menus will assist in this.
Test mode screens and menus
The six test modes are selected by pressing the appropriate MODE key. These are light blue, with
dark blue lettering. (Item 16 in Fig. 3-1, Front panel). Select each in turn and observe the display
presented.
Each area of six soft key labels forms a menu. Various menus are called up as a result of selecting
a change of test mode or by pressing a soft key within a test mode.
Fold out diagrams will be found at the end of this chapter, which show the screens displayed when
each of the mode keys is pressed. These also show branching to the second or third level screens
and menus. A diagram of the screens accessed from the HELP/SETUP key is also included.
These fold out diagrams are numbered to correlate with the associated key position as follows:-
(1.0) HELP/SETUP
(2.0) Tx TEST
(3.0) Rx TEST
(4.0) Dx TEST
(5.0) SYSTEM
(6.0) SPEC ANA
(7.0) AF TEST
References in the manual to specific screens on the fold out diagrams is given as in the following
example:-
Fold out diagram (2-2-3). This is the screen shown after pressing the [Tx TEST] mode key, then
the [Tx Power] key (second key down), followed by the [Harmonic analysis] key (third key
down). Where there are keys on both sides of a screen, keys 1 to 6 are on the left, keys 7 to 12 on
the right.
To move to the top level menu of any test mode, including the currently active mode, press the
relevant ‘MODE’ key.
For detailed use of specific TEST MODES see the section later in this chapter relating to that test
mode.
