fumes.
Operators must not remove the cover or part of the housing. The analyzer must
not be repaired by the operator. Component replacement or internal adjustment
must be performed by qualified maintenance personnel only.
Never operate the analyzer if the power cable is damaged.
Never connect the test terminals to mains.
Electrostatic discharge can damage your product when connected or
disconnected from the DUT. Static charge can build up on your body and damage
the sensitive circuits of internal components of both the product and the DUT.
To avoid damage from electric discharge, observe the following:
Always use a desktop anti-static mat under the DUT.
Always wear a grounding wrist strap connected to the desktop anti-static mat
via daisy-chained 1 MΩ resistor.
Observe all the general safety precautions related to operation of equipment
powered by mains.

can significantly affect the measurement capabilities of the analyzer. To clean the
test ports (as well as other connectors of the analyzer), use the following
procedure:
Using compressed air remove or loosen the contamination particles;
Clean the connectors using a lint-free cleaning cloth wetted with a small
amount of ethanol and isopropyl alcohol (when cleaning a female
connector, avoid snagging the cloth on the center conductor contact
fingers by using short strokes);
Dry the connector with low-pressure compressed air.
Always completely dry a connector before using it.
Never use water or abrasives for cleaning any connectors of the analyzer.
Do not allow contact of alcohol to the surface of the insulators of the
connectors.
WARNING
Never perform cleaning of the product if the power cable is
connected to the power outlet.
Never clean the internal components of the product.
Storage
Before first use store your equipment in the factory package at environment
temperature from 0 to +50ºС and relative humidity up to 95% (at 25ºС).
After you have removed the factory package store the equipment at environment
temperature from +10 to +35ºС and relative humidity up to 80% (at 25ºС).
Ensure to keep the storage facilities free from dust, fumes of acids and alkalies,
