Safety
This meter is intended for origin of installation use and protected, against the
users, by double insulation per EN61010-1 and IEC61010-1 2
to Category IV 600V and Category III 1000V; Pollution Degree 2. The meter
also meets UL 61010-1, 2
Edition (2004), and UL 61010B-2-031, 1
Audible signal will sound if the resistance is less than 35 (approx.), test
The term stands for "Root-Mean-Square," which represents the method of
calculation of the voltage or current value. Average responding multimeters
are calibrated to read correctly only on sine waves and they will read
inaccurately on non-sine wave or distorted signals. True rms meters read
accurately on either type of signal.
