3.4.3 CONTROLLING THE OUTPUT USING THE BOP AS A POWER AMPLIFIER
The BOP can function as a power amplifier by means of the External Reference input at the
Analog I/O port. This analog signal controls the main channel of the BOP. To use the BOP as a
power amplifier see the following instructions for using the external reference: PAR. 3.4.3.1 for
fixed gain, PAR. 3.4.3.2 for variable gain by establishing the maximum full scale output.
3.4.3.1 FIXED GAIN USING EXTERNAL REFERENCE CONTROL
The main channel of the BOP, voltage in voltage mode, and current in current mode, can be
controlled by an external reference voltage, 0 to ±10V applied at pin 11, referenced to pin 10, of
the Analog I/O port. The input impedance for this signal is 20K ohms. This feature is enabled as
follows:
1. From the power-up screen, press
$
, highlight Reference Input and press
!
. Highlight
External and press
$
to save. Then press
%
to apply the changes (without saving for
power-up) and exit. NOTE: This setting can be saved for power-up only by using the pass-
word-protected Power-up Settings menu (see {PAR. 3.3.7), otherwise internal references
are used for both main and protection channels upon power-up.

TEST
DISPLAY Status (see NOTE below) Automatic test, reports status messages (see NOTE below).
KEYPAD Status (see NOTE below) Requires depressing keys indicated on LCD.
This test requires pressing every key on the keypad, plus moving the
ADJUST control clockwise and counterclockwise, with the ADJUST control
depressed and released. As the keys and control function pass the tests, the
corresponding function on the LCD is highlighted. When the last test is suc-
cessful, the LCD displays “passed.” The test must be completed within two
minutes, otherwise a “Failed” indication is displayed.
