AC Power Source
The 1560 requires an AC power source. See Section 3.1, Specifications, for
deatils. The power supply automatically adjusts to the mains voltage. The 1560
may draw up to 0.5A.
The AC power cord attaches to the 1560 at the power socket located at the rear
of the second section of the base. The power switch is also located at the rear of
the second section.
4.3
Power On Self-Test
When power is turned on, the 1560 will perform a self-test checking all the
components in the system including the module bus and each module. It will
report the status of each component on the screen. If an error occurs with the
bus or modules it may be the result of an improper connection. Turn the power
off, check the connections between the modules, and remove and reattach mod-
ules if necessary. If modules have been removed or rearranged, a warning mes-
sage may appear noting that the module configuration has changed and that all
probe parameters should be checked.
4.4
Adjusting the Screen Contrast
When the 1560 is first powered on, the screen may appear faded, dark or blank
if the contrast is not properly adjusted. Use the
<C>
buttons located at the
bottom of the left side of the front panel to adjust the contrast. As the 1560
warms up, the contrast may need to be adjusted.
4.5
Making Measurements
The procedure for configuring the 1560 to make measurements on a particular
input channel involves a few simple steps: select the input channel, set the con-
version type and probe characterization coefficients, and enable measuring.
These steps are explained below.
4.5.1
Selecting Input Channels
Input channels are selected by number using the
PRIM CHAN
soft-key in the
INPUT
menu (see Section 5.1.2). The channel is selected from a window
showing a list of all available input channels. Each channel in the list is identi-
fied with the device name, the channel number, and probe serial number. The
channel is selected by using the
UD
buttons to move the cursor to the desired
channel and pressing
ENTER
.
