[1] All k Chek voltage ranges are specified from 60 counts to 100 % of range. Because inputs below 60 counts are not specified, it is possible and
normal for this and other true-rms meters to display non-zero readings when the test leads are disconnected from a circuit or are shorted
together.
[2] Crest factor of ≤3 at 4000 counts, decreasing linearly to 1.5 at full scale.
[3] After measuring voltage, a wait time of 1 minute is required to maintain accuracy of ohms, capacitance, diode test, and continuity.
