Best handheld dmm, at any price?

Re: Best handheld dmm, at any price?

Handhelds WILL get dropped sooner or later and rained on, either by nature in the field, a clumsy coffee/tea/shiraz/vodka disaster
or some stinking male cat marking its meter territory when you're at the van getting parts and finishing off that donut

Either surround 'best handheld dmms' with a foam skin and perspex front guard,


or a Fluke 28-11 may be the hot favorite in 'Meter Survivor' or "Last Meter Standing' reality shows :clap:

First explain that my English is not good and I use Google Translate.
I have a DT4282 that has been in use for more than two years.
The DT4282 has many advantages. Some of its features are not comparable to other hand-held multimeters.
Like its DCV range and resistance range speed, resistance range accuracy, and stability, temperature drift and so on.
There is 1uV resolution and stability of the DCV I appreciate and often use.
There is also a very good frequency response of its ACV.
And its ultra-fast PEAK function.
The above mentioned are far superior to other hand-held multimeters of the same grade.
But I also see  many disadvantages  it is:
It does not have an analog bar, the continuity test response time is 10mS, the display shows dark,
Only voltage AC+DC function, no current AC+DC function, AC voltage, current speed is not fast,
Capacitance is very slow, and AC voltage and current mantissa are forced to zero within the word is below "999".
Large reading range when the signal  above 100 KHz  for ACV measurements, and the upper limit for frequency measurement is 500 KHz, and
The frequency of many test signals cannot be displayed, and sometimes the manual switching range does not respond.
PEAK function does not have mV range, AC+DC and AC/DC dual display have no mv range.
The FILTER function has only 600V  and 1000V range and no 6V and 60V range.
The recalled stored data and current measurement data cannot be displayed in the same screen.

So I made the following suggestions to the manufacturer:

Functional improvements:
1: Continuity test response time increased to 1ms, and Increase resolution to 0.01OHM
2: Use high-brightness, high-contrast display (just now display is dark)
3: Diode range increases resolution to 0.0001V
4: Open circuit of resistance range is changed to "OL" without flashing
5: Increase the measurement speed of the capacitor
6: Cancel auto-zero function in “999” character of AC range
7: Increase the AC speed and AC/DC dual display measurement speed, and instead when performing AC/DC dual display automatic speed measurement, the ranges of AC and DC are not related and the ranges are independent.
8: Improve the reading stability of the signal above 100KHZ by ACV (currently the reading is too large)
9: Increase the upper limit of the frequency measurement range and improve some frequencies can not be displayed
10: Improvement Sometimes transform Range Does Not Respond
11: Improvement: The “?”, “?” and “RANGE” keys on the right side of the panel together constitute the quick function key for range switching, similar to the desktop multimeter

Increased functionality:
1: PEAK function increases mv range
2: increase the recalled stored data and the current measurement data with the screen display
3: FILTER function increases 6V, 60V range
4: Increase the low impedance mode function
5: Add analog bar display
6: Increase range indication
7: increase the maximum, minimum, present value (real-time measurement) with the screen display
8: increase the positive peak, negative peak, present value (real-time measurement) with the screen display
9: AC+DC and AC/DC dual display increase the mv range
10:  Add current AC+DC function.
11:  Add automatic power off time setting function.

Synthtech:
Interesting. I find that the capacitor autoranging in my DT4282 is much, much faster than my Keysight.

VEGETA:
So what meter do you suggest for <100$?

It has to include measuring capacitors accurately and true rms...etc.

Right now my main is Aneng 8009 and I got another 8002 as a spare. I plan to get the 121gw when it is ready to sell, I guess that could be my high-end meter. Significantly better than 8009.

And I have a question: Why Fluke 87 is always the most used one? always considered the standard... can someone explain this?

None, basically. Between ANENGS and $100 there's no real advantage.

No DMM is going to measure capacitors accurately. You need an LCR meter for that.

Because it just works. And keeps on working.
