Calibration Information
Accuracy specifications are given as: ± ([% of reading] + number of least significant digits) ac readings
are ac-coupled, true rms, and are valid from 5 % to 100 % of range. Add ±(2 % of reading + 2 % of
range) for 1.4 < CF ≤ maximum CF. Maximum CF is 3 full scale, 6 half scale.

In 40 Ω and 40 mV ranges, thermals may introduce additional errors. Maximum accuracy is obtained when
*
both probe tips are maintained at the same temperature.
** Accuracy applies when measuring film capacitors or better and the open lead reading is subtracted from the
measurement. This meter uses a dc-type measurement technique.
*** Accuracy applies after lead resistance compensation.
