User‟s Guide for DM3000 Series
[1] Specifications are for 60 minute warm–up, selecting 5 3/4 reading resolution and calibration temperature
18 ℃ – 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 current is
typical.
Variation in the current source will create some variation in the voltage drop across a diode junction.
Settling Considerations
Reading settling times are affected by source impedance, cable dielectric characteristics, and input signal
changes. Typically, settling time <1.5s when source impedance less than 1kΩ.
