1. Specifications are based on 30 minutes warm-up time and calibration temperature within 18°C to 28°C. In manual range, the settling time is
2. 6 seconds while in autorange, the first measurement accuracy is < 1%.
3. Specifications are for sine wave inputs more than 5% of range. 120% over range on all ranges except 250 VAC. Maximum crest factor of 5 at full scale. Input
impedance is 1 MΩ in parallel with capacitance less than 120 pF, AC couple with up to 300 VDC.
4. Additional error to be added as frequency more than 30 kHz and signal input less than 10% of range. 30 kHz to 100 kHz: add 0.003% of range per kHz.
5. Input signal has to be more than 50 Vrms.
6. Input protected with externally accessible 2 A, 250 V fast blown fuse.
