  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.
