7 Specifications
Specification Assumptions
• The DC specifications are defined for measurements
which are taken after at least 1 minute of warm- up time.
• The AC and AC+DC specifications are defined for
measurements of sine wave and are taken after at least 1
minute of warm- up time.
• The accuracy of the multimeter may be affected when
making measurements in an environment where
electromagnetic interferences or significant electrostatic
charges are present.
