SECTION 4 - CALIBRATION
4.1 GENERAL
This section contains the calibration instructions for the Power Supply. It is recommended that
the user be familiar with Local Mode operation (PAR.3.2) before calibrating the unit.
A full calibration consist of a voltage calibration and a current calibration. Both voltage and cur-
rent calibrations consist of zero, max and min, and protection limit calibration. In addition, the
control signals required for series and parallel operation of multiple units are also calibrated. It is
recommended that the unit be recalibrated annually.
In order to enter the calibration mode the correct password may be required (see PAR. 3.2.4.4).
If the password has been lost, call the factory and a special password will be provided. During
the calibration, new calibration data is computed which is then stored in the nonvolatile memory.
Calibration of the BOP is performed in one of three ways: locally using the front panel keys
(PAR. 4.4) or remotely by sending commands through either the GPIB or RS 232 bus (PAR.
4.3). These two ways cannot be combined.
NOTE: During calibration, various circuits of the BOP are verified. If an error occurs during the
verification process, the unit will beep and an error 24(x), Hardware, (see PAR. B.132)
will be placed in the error queue.
