Notes on Specifications:

1. 20% over range on all ranges except 1000 VDC and 10 A range.

2. Specifications are for 4-wire Ω or 2-wire Ω using NULL function. If without NULL function, add 0.2 Ω additional error.

3. Continuity thresholds is fixed at less than 10 Ω

4. Specifications are for the voltage measured at the input terminals only.
