Conducting Measurements - VOLTCRAFT VC-539 Mode D'emploi

10. CONDUCTING MEASUREMENTS

Never exceed the maximum permissible input values. Do not touch any circuitry
or connection points when voltages exceeding 25 V/ACrms or 35 V/DC might be
applied. Risk of fatal injury!
The voltage between the meter's connection points and ground potential may not
exceed 600 V DC/AC in CAT III.
Before conducting measurements, check both the safety test leads and the
current clamp for damages. Do not operate the product if it or the test leads are
damaged. Risk of fatal injury!
Hold the test leads by the grooved grips only. Never hold the test leads directly
near the test prods.
Always hold the current clamp beneath the handle marking (2). Never hold the
current clamp directly near the current clamp sensor (1).
Always remove the test prods from the object under test before changing the
measurement range or mode.
Disconnect the test leads from the test lead jacks as soon as you have finished
conducting measurements with the test leads.
Exercise extreme caution when conducting measurements on busbars and non-
insulated wires. Risk of electric shock!
Wear appropriate protective clothing (i.e. safety gloves) to prevent injury due to
electric shock, flashover, etc.
When measuring current, make sure that the safety leads are not connected to the
product.
Do not use the product directly before, during or shortly after a thunderstorm.
Lightning may cause power surges. Make sure that your hands, shoes, clothing,
the floor, circuitry and connection points, etc. are dry.
Do not use any meter accessories that do not match the product's specifications.
Avoid use in the direct vicinity of:
• strong magnetic or electromagnetic fields and
• transmitting antennas or high-frequency generators.
Failure to do so may falsify readings.
