notes preceded by symbol
measurements, carefully observe the following instructions:
 Do not carry out any measurement in humid environments.
 Do not carry out any measurements in case gas, explosive materials or flammables are

 Avoid any contact with the circuit being measured if no measurements are being
carried out.
 Avoid any 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.
