1. All VChek 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. Minimum measureable input in VCHEK autorange is 3 VDC. For measurements below 3 VDC, push Range button twice to get to 6 VDC manual range.
4. After measuring voltage, a wait time of 1 minute is required to maintain accuracy of ohms, capacitance, diode test, and continuity.
