1. Specifications are based on 30 minutes warm-up time, NPLC 20 resolution, calibration temperature within 18°C to 28°C, and Null function enabled. For
NPLC 0 and 0.025, add 0.01% of range.
2. 120% over range on all ranges except 300 VDC. Input protection up to 300 VDC.
3. Input protected with externally accessible 2 A, 250 V fast blown fuse.
4. Specifications are applicable with Null function enabled. Otherwise, add 0.2 Ω additional error. Input protection up to 300 VDC. Specifications apply for
NPLC ≥ 1.
5. Specifications are for the voltage measured at the input terminals only.
6. Continuity threshold is fixed at less than 10 Ω.
