    4.16 C ALIBRATION 4.16.1 Introduction T 1000 PLUS does not need to be calibrated, as metering circuits employ high stability components. It is suggested to check the unit every 2 years, by comparing T 1000 PLUS measurements to external meters. Tests should be performed with an high accuracy multi-meter, that should guarantee a maximum AC measurement error of 0.1%, both for...
