What to Do In Case of Product Failure
If an obvious failure occurs during operation (for example the display is not lit, the
fan is not turning), the Product must be powered off immediately. First, check the
line power fuse located on the rear panel of the Product. See Access the Fuses.
If a Product range or an operating mode is not functioning and the user cannot
correct the fault, contact the Fluke Calibration Service Center.
Subtle faults can cause different symptoms and have different causes. Usually,
they cause instability of some parameter. Subtle defects can be caused by
events such as unacceptable distortion or degraded insulation. In this case
contact the Fluke Calibration Service Center.
If the rules for correct operation are not adhered to, it may seem as if the Product
has a subtle defect. Some abnormalities may actually be due to circumstances
outside of the Product, or operator error. See Prepare the Product for Operation.
Most frequent cases of defects are:
• Mains voltage out of tolerance limits, unstable, distorted voltage or there are
voltage spikes present.
• Incorrect grounding of the mains circuit (bad connection of the ground
terminal of the mains outlet).
• Proximity to sources that have either high conducted or radiated
electromagnetic fields.
• Strong electrostatic or electromagnetic fields which can cause major
instability during usage, particularly when working with high impedance
(>1 MΩ).
DUT Calibration Examples
This section demonstrates the use of the Product with actual calibration
examples for various DUTs. For each Product function, calibration steps along
with connection figures are provided for at least one DUT.
