1. Specifications are based on 30 minutes warm-up time, NPLC 20 resolution, and calibration temperature within 18 °C to 28 °C. 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 for 4-wire Ω or 2-wire Ωs using null function in KMM software. If without null function in KMM software, 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.

NOTE: To ensure better measurement results and to guard against the change of environment or setup, always enable the Null offset.
