CALIBRATION
Your VMS-1 portable power supply itself does not require any calibration for normal operation.
The onboard digital Voltmeter and Ammeter will also hold its normally calibrated settings during
the lifetime of your VMS-1 for all normal indoor operations. In the rare case that either meter
needs calibration adjustments, the procedure for doing so should be performed by qualified
technical personnel such as the Phenix Technologies Service Department during a scheduled
service appointment.
MAINTENANCE
During the lifetime of your portable power supply, certain items will need replacement. Common
replacement parts are listed on page 7-
1 under “Recommended Spare Parts.” With the exception
of the input and output cables, all other components that may need replacement require the
removal of the front panel from the Portable Power Supply enclosure case. This is done through
the removal of the mounting screws and washers along the perimeter of the front panel, and
pulling the panel with its attached components from the enclosure. After the needed components
are replaced, replace the front panel with the mounting screws and washers, carefully
hand
tightening
the screws into place
.
Using screwdrivers or over-tightening the screws may cause the
brass hardware to dislodge from the frame.
