FOR YOUR ENTERTAINMENT of course...owon xdm 3041 cost about usd 300 or so in oct 2022,,, additional usd 50 or so will get u siglent....usb ext data almost useless... internal 1000 data mem works fine,,, once saved into internal, yes u can back n forth to see table, histo and trend again,,, but,, accuracy , who knows. one can only guess, right.....LIMITS, both HI and LO work nice...you can set any values for ANY PARAMETER, current, volt,ohms, freq, temp....and Limits will sound beeping alarm and go RED color screen, if OVER or UNDER your set limits... DUAL modes, can be against Volts and Currents too, but NOTE RELAY going nuts, as in ALL multimeters,...NO CURSORS,,, pretty much what more expensive meters can do...but, with the owon name and design and limitations,,,,,seems to be top secret, but owon is bit more than 60,000 count,, Noise floor for micro amp DC seems to be around 20 to 40 nano amps....maybe.. IF you play above 50 nano amps DC, results are Somewhat repeatable...
