Introduction The Fluke 8558A 8 1/2 Digit Multimeter and 8588A Reference Multimeter (the Product or Multimeter unless otherwise specified) are for demanding and precise measurement applications. The Product functions in both stand-alone and systems applications. 8 1/2 digit resolution provides high performance and makes the Product well suited for application use in standards labs, calibration labs, engineering labs, and systems use.
Calibration Interval and Performance Fluke Calibration recommends that the Product be calibrated on one of 2-year, 365-day, or 90-day intervals depending on the requirements of the applications for which the Product is used. During manufacture, the Product is adjusted and verified with low uncertainties, reflected in the Absolute Specifications.
Performance of the Product after calibration should be determined by combining the applicable calibration uncertainties provided by the calibration equipment with the 8508A Relative to Standards specifications. (Fluke Calibration recommends RSS summation). Calibration Adjustment Overview The Product has two sets of stores: Certified and Baseline. Only the Certified stores can be changed during adjustment.

8588A/8558A Service Manual Not all function range combinations need to be adjusted. To improve efficiency, some adjustments are derived from other adjustments, so it is important to follow the adjustment process in the given sequence. Individual points can be adjusted in isolation later if required.

Reference Multimeter / 8½ Digit Multimeter Calibration Interval and Performance 10. Continue through the adjustment process until all steps are complete. The last adjustment for 8558A is: Step 703: Current Zero. The last step for 8588A is Step 704: Capacitance zero. Table 2. Table Points...
Calibration Verification The permissible errors shown are the 99 % confidence, 1-year, absolute errors. These error values include Fluke Calibration calibration uncertainty. Adjust the permissible error values to reflect the actual measurement uncertainty if they are different from the listed values.
