CALIBRATION
Your VMS-2 portable power supply itself does not require any calibration for normal operation.
The onboard digital Voltmeters and Ammeters will also hold their normally calibrated settings
during the lifetime of your VMS-2 for all normal indoor operations. In the rare case that any 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.”
