4.9.2.3.- Batteries and External Units Power Supply (Battery & Lnb)
This function allows you to check the charge state of the batteries, as well as the supply current and voltage of the external units. From
the TV operation mode, simply press key ENTER [5] select the Battery & Lnb function and press key ENTER [5]again. You will see a screen
like the following one:
Figure 12.- Battery&Lnb function.
The top part of the screen displays the battery voltage (6,1 V in previous figure), both numerically and with a bar graph. The arrow
labelled L Bat below the horizontal bar signals the low battery level where the battery should be charged. When batteries are fully charged,
battery voltage indication is 6.1 V or higher.
The bottom of the screen shows the voltage supplied to the external units (V LNB, 12.6 V in the figure above) and the current supplied
(I LNB, 200.0 mA in the example).
To leave this function press key ENTER [5].
4.9.2.4.- Data Logger Function
The Data logger function allows the user to carry out, store and/or print out up to 9801 measurements in a fully automatic way. It may be
understood as a measurement matrix whose columns address the 99 measuring configurations (defined in the 99 memories of the
equipment) and whose lines permit to store 99 measurements for every measuring configuration (conducted in different points of the system
or in the same point on different times).
Before to proceed to take measurements by means of the Data logger function it is necessary to store the measuring configuration/s in
the memory by using the Store function (see paragraph 4.12.1).
To select the Data logger function activate the TV mode functions menu, by pressing key ENTER [5] when in the TV operation mode.
Then, use keys
[6] to select the Data logger field and press key ENTER [5], the DATALOGGER screen will appear automatically.
