Calibration
The Routine Calibration should be performed every 12 months. Non-routine Calibration is only required
if a related assembly is replaced or if the periodic calibration is unsuccessful. Calibration of the BPS
system can be performed from the front panel or over the bus. The BPSGUI program provides several
calibration screens for this routine calibration but not for non-periodic calibration. This section covers
calibration from the front panel. Refer to the BPSGUI on line help for information on using the BPSGUI
program to perform routine calibration.
Full-scale output calibration is done using the internal measurement system. As such, it is important to
calibrate the AC voltage measurements before performing an AC full-scale output calibration.
Note:
Perform the Measurement calibration first.
The cardinal calibration points used during calibration are chosen to obtain optimal performance at the
typical operating points of the BPS Series. If the typical application in which the BPS system is used is
unusual, it may be better to calibrate it at different operating points than the ones used in this manual.
Also, if the required load values for current calibration are not available, the programmed voltage may be
adjusted to obtain the approximate current (typically close to maximum available current per phase).

Recommended Calibration Equipment
Digital Multimeter:
Agilent 3458A or equivalent / better.
1 mOhm Current Shunt:
Isotek Model RUG-Z-R001-0.1.
Load Bank:
Various high power load resistors or a resistive load bank will be
needed. (E.g. Avtron ) Size of the load bank depends on model and
phase mode. A load is required to perform the current measurement
calibration near full scale. Current measurement calibration should
be done on the lowest available voltage range.
The accuracy and value of the load resistor is not critical as long as
the current drawn is sufficient to operate the AC Source in the upper
current range (80-100 %). Suggested values of load bank settings are
shown in Table 7-1.
PC with CI BPSGUI:
Optional. Consult factory for further information.
