Notes：
[1] Specifications are for 60 minute warm–up and set reading resolution as 5¾ and calibration
temperature between 18 ℃ and 28 ℃.
[2] 20% over range on all ranges except DCV 1000V, ACV 750V, DCI and ACI 10A range.
[3] Specifications are for 4–wire resistance function or 2–wire resistance using Math Null. Without
Math Null, add 0.2 Ω additional errors in 2–wire resistance function.
[4] For each additional volt over ± 500 VDC add 0.02 mV of error.
[5] For current terminal, > 7A DC or ACRMS for 30 seconds ON and 30 seconds OFF.
[6] Accuracy specifications are for the voltage measured at the input terminals only. 1 mA test
