2.1 UNPACKING AND INSPECTION
This instrument has been thoroughly inspected and tested prior to packing and is ready for
operation. After careful unpacking, inspect for shipping damage before attempting to operate.
Perform the preliminary operational check as outlined in PAR 2.5. If any indication of damage is
found, file an immediate claim with the responsible transport service.
2.2 TERMINATIONS AND CONTROLS
2.2.1 FRONT PANEL CONTROLS AND INDICATORS. Three 4-digit, 7-segment LED displays and
six individual LEDs on the front panel show operating status as shown in Figure 1. A rotary
encoder (CONTROL) allows the user to: a) adjust the selected load parameter, b) define the
resolution of the rotary encoder, c) select the operating mode. A momentary pushbutton switch
(LOAD) with integral LED indicator allows the user to alternately a) engage the load, allowing
the source or Unit Under Test (UUT) to draw current and b) disengage the load, stopping cur-
rent flow. The LOAD LED indicator colors show the load connection status and indicate a fault
condition if one exists.
Figure 2-1 shows the front panel of standard units; Figure 2-2 shows the front panel of dual-
channel units. Table 2-1 presents the functions of all front panel controls and indicators. Front
panel controls listed in Table 2-1 are duplicated for identical (but independent) channels A and B
of the dual-channel units, with the exception of the single POWER switch which applies to both
channels.
2.2.2 REAR PANEL CONNECTIONS. Figure 2-3 shows the rear panel of standard units; figure 2-4
shows the rear panel of dual-channel units. Table 2-2 presents the functions of all rear panel
connections. Rear panel connections listed in Table 2-2 are duplicated for identical (but inde-
pendent) channels A and B of the dual-channel units, with the exception of the single power inlet
connector and fuse which apply to both channels.
