Question 1

Is it true rms with the amps?

Accepted Answer

Just an FYI to readers - To clarify what they mean by True RMS. True RMS, VRMS, ARMS and WRMS is the RMS measure of both the AC + DC components, it's integration of the area under the curve. This meter measures VACrms and AACrms, so it separates the DC component. It should state TRUE AC RMS, but like most meter manufacturers, they don't. There's a lot of misunderstanding on this thanks to marketing in companies. Take a look at a Fluke 187 or 189 where they actually measure TRUE RMS, but on the meter they call it AC+DC (in Blue). Most people are fine with this, since they typically measure line voltage or clean DC (battery or SMPS supplied). However, measure a DC source with high ripple current and you will not get a real measure, such as in automotive battery chargers that use a linear charger (large transformer based, not SMPS). Knowing the True RMS allows you to properly design for things such as thermal, efficiency and safety (fuses, breakers, thermal cutoffs, etc..) and to prevent over charging or over powering a battery or device. Class 2 devices, as those that fall under UL1310, have to comply to VRMS up to 2kHz for both indoor and outdoor ratings. Landscape lighting, LV pool lighting, USB 3.x Power Port also must comply. The reason for this in LV applications is because of the breakdown voltage of the skin. How to tell, if the AC symbol on the display only has a tilde ~ it's ACrms. If it has both the tilde ~ and a straight line – above it, its RMS. Some meters (Fluke 187, 189, 287 & 289) use the DC for both DC and RMS, so it will have both if the second function feature is RMS. The Dashed straight line on the flukes means it can also properly measure pulsed DC.

Question 2

what is the minimum dc amperage it will measure? 1ma ?

Accepted Answer

In 6A range, resolution is 0.001A, the test range is 0.001A~6A.
In 60A range, resolution is 0.01A, the test range is 0.01A~60A.
In 100A range, resolution is 0.1A, the test range is 0.1A~100A.

Question 3

with the clamp can you measure amps in DC ?. Up to how many amps maximum?

Accepted Answer

Yes, with the clamp, the tester can not only measure amps in DC, but also measure amps in AC, the maximum amps is 100 amps with 1mA resolution.

Question 4

Is this basically the same unit as the Uni-T 210D?

Accepted Answer

This meter has been upgraded a lot compared to Uni-T 210D

1. This meter has higher precision than Uni-T 210D (6000 counts vs 2000 counts), especially measure current with clamp, for example, when measure current approximately 2.5A, this meter display 2.493A, Uni-T 210D only display 2.49A

2. This meter added many functions: Live wire check, Low Impedance voltage test, measure microamps μA by terminals, etc.

3. This meter has many upgraded designs: Side probe holder design for easy test, Back clip design make it more portable, etc.
