Notes:
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 V dc. For measurements below 3 V dc, push Range button twice to get to 6 V dc manual range.
4 After measuring voltage, a wait time of 1 minute is required to maintain accuracy of ohms, capacitance, diode test, and continuity.
