6 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 MX system can be performed from the front panel or over the bus. The
VIRTUAL PANELS 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
VIRTUAL PANELS on line help for information on using the VIRTUAL PANELS 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 and DC voltage measurements before performing an AC and DC
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 MX Series. If the typical application in which the MX 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).
6.1 Recommended Calibration Equipment
Digital Multimeter:
Fluke 8506A or equivalent / better.
HP 34401A 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 6-1.
PC with CI VIRTUAL PANELS: Optional.
For MX15-1Pi programmable Impedance calibration only:
Digital Phase Meter:
Krohn-Hite model 6610 or 6620 (GPIB) or equivalent.
0.02° accuracy, 0.01° resolution or better.
