7.1. MAINTENANCE SCHEDULE Table 7-1 below outlines the suggested maintenance procedures and intervals for ensuring the 480M continues to operate accurately and reliably. These intervals are based on continuous (24 hours a day – 7 days a week) operation. These intervals may be lengthened for intermittent operation.
High voltage may be present when power is connected to the instrument. Figure 7-1 shows the internal layout of the 480M. These figures will be referenced in the procedures that follow. Note the caution areas, Power Supply and Electrical Terminal Block, where high voltage (line voltage) may be present when power is connected to the instrument.
