with the utmost attention.
Before and after carrying out the measurements, carefully observe the following
instructions:
• Do not carry out any voltage or current measurement in humid environments.
• Do not carry out any measurements in case gas, explosive materials or flammables are
present, or in dusty environments.
• Avoid contact with the circuit being measured if no measurements are being carried
out.
• Avoid contact with exposed metal parts, with unused measuring probes, circuits, etc.
• Do not carry out any measurement in case you find anomalies in the instrument such
as deformation, breaks, substance leaks, absence of display on the screen, etc.
• Pay special attention when measuring voltages higher than 20V, since a risk of
electrical shock exists.
In this manual, and on the instrument, the following symbols are used:
