Voltages
(Continued)
The range digit can be the number 1 specifying low range
(0-10 volts for CV, 0-2A for CC) or the number 2 specifying
high range (0-50 volts for CV, 0-10 amps for CC). The mag-
nitude digits can be any number from 0-999 (see figure 9-3).
Since 999 is the maximum value for the magnitude digits, the
programmable output ranges are as shown in figure
9-3.
Figure 9-4 shows a FORTRAN test program and a
generalized subroutine which allows the 6002A to be pro-
grammed from 0-49.9 volts by inputting the desired voltage
value from a user terminal. The equations required to do the
operation are straight forward and can be found in the sub-
routine.

Range programming for the CC operation can be
done in a similiar fashion.
The following paragraphs provide detailed operating instruc-
tions required to program the 6002A for constant voltage or
constant current operation. Refer to figures 9-5 and 9-6
for
adjustments and component locations respectively.

Constant Voltage Operation
To program the supply for constant voltage operation:
a.
Connect the supply to an HP 1000 controller.
b.
Set the mode switches on the rear of supply to the CV
'''--./
position
,
c.
Turn on the supply.
d.
With the supply's output terminals open, program the
supply for the desired output voltage.
e.
Connect a short across the supply's rear panel output
terminals and adjust the front panel current control for
the
desired maximum output current. If a load change
causes this current limit to be exceeded, the supply
automatically crosses over to constant current operation
at this preset current limit and the output voltage drops
proportionally.
Constant Current Operation
To program the supply for constant current operation, you
must first adjust HP-IB option 001 for CC operation (steps a
through h).
a,
Turn off the supply and set mode switches to the CC
position.
b.
Turn the VOLTAGE control on the front panel fully
clockwise.
