I want to calculate the temperature coefficient for a digital multimeter. The datasheet I read it is calculated as:

0.1*(specified accuracy)/°C (<18°C or >28°C)

Do you know what specified accuracy stands for?

I mean, can I consider specified accuracy as the composition of multimeter accuracy and resolution?

Thank you in advance.

    \$\begingroup\$ I wouldn't think that it "stands for" anything. It's the accuracy, as specified in the meter's handbook. \$\endgroup\$ – Simon B Oct 4 '18 at 14:13
  • \$\begingroup\$ I think that the accuracy is specified by calibration report of the instrument. \$\endgroup\$ – Railectric Oct 4 '18 at 14:50

According to Full scale Accuracy:

Accuracy of a multimeter is given as a function of specified accuracy .

Accuracy = (specified accuracy / 100 ) * FSD.

FSD refers to full scale deflection which is the largest value can the multimeter measures.
