Introduction and Specifications
Introduction
Refer to the 5790B Operators Manual (located on the Fluke Calibration website)
for complete operating instructions,
This manual provides performance test, calibration adjustment, theory of
operation, troubleshooting, and repair procedures necessary to verify and
maintain performance of the 5790B (the Product).
Note
In many of the procedures in this manual, the Product is referred to
as the Unit Under Test (UUT).
The performance tests are based on the published 1-year specifications for the
Product. Fluke Calibration recommends the performance test as an acceptance
test when the Product is first received and later as a procedure to ensure that the
Product meets its published specifications. Fluke Calibration recommends a 1-
year calibration cycle for the Product.
Use calibration adjustments to correct out-of-tolerance parameters so they meet
published specifications. If the Product fails the performance test, it is an
indication that the Product requires calibration adjustment and/or repair. While
calibration adjustment can be accomplished without removal of the covers, repair
requires access to the interior of the Product.
Environmental and warm up conditions required for the performance test and
calibration adjustments are stated at the beginning of each of the respective
sections.
Note
Repairs detailed in this manual are to the Modular-level only. Return
the Product to Fluke Calibration or take the Product to a local Fluke
Calibration Service Center for deeper-level repair.
