User’s Guide for DM3000 Series

5-2

[1] Specifications are for 60 minutes warm–up and select 6½ reading resolution.

[2] Relative to calibration standards.

[3] 20% over range on all ranges, except DCV 1000V, ACV 750V, DCI and ACI 10A range.

[4] 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.

[5] For each additional volt over ± 500 VDC add 0.02 mV of error.

[6] Accuracy specifications are for the voltage measured at the input terminals only. 1mA test current is typical.

Variation in the current source will create some variation in the voltage drop across a diode junction.

[7] For current terminal, > 7A DC or ACRMS for 30 seconds ON and 30 seconds OFF.

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.
