 Specifi cations 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 fi rst measurement accuracy is < 1%.

[2]

 Specifi cations 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.

[3]

 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.

[4]

 Input signal has to be more than 50 Vrms.

[5]

 Input protected with externally accessible 2 A, 250 V fast blown fuse.
