Errors And Load Restrictions; Ex-Certification Data - Fluke 28 II EX Safety Instructions

4. Errors and load restrictions

If there is any question that the safety or integrity of this Product is compromised, remove it from
operation and the Ex-hazardous areas immediately. Also, do whatever is necessary to prevent
Product operation by others until the Product is examined by an ecom certified technician.
It is recommended that you send the Product to the manufacturer to be examined.
Because the safety and reliability of the Product can be at risk, do not operate the Product if:
- Visible damage is found in the housing of the Product.
- The Product has had an excessive load put on it for which it is not designed.
- The Product was not stored correctly.
- The Product has sustained damage in transit.
- Illegible inscriptions or lettering shows on the Product.
- A Product malfunction occurs.
- Obvious measurement inaccuracies occur.
- Measurements/simulations are no longer possible with the Product.
- Permitted tolerances or threshold values were exceeded.
