I have a Metrix mtx3283 (the precursor of mtx3293, IIRC same specs but with optical data cable instead of BlueTooth).

Mine is slow to power-on, very slow while measuring (1 sec or so), very-vey slow while auto-ranging (2-3 seconds), very-very-very slow on capacitances (tens of seconds ::)), and the AUTO-HOLD function is broken by design.  Plus it doesn't remember all the settings at the next power-on (e.g. it doesn't remember the manual range), which is very annoying, and the display is hard to read, and has a really ugly blue backlight, and an audible SMPS squeak while the backlight is on.

Did they fix those pitfalls in mtx3293?

3293 is also optical cable.
There is version with Bluetooth.
Screen is color LCD and is OK.


Boot is less than a second. Fast.
Auto ranging is very fast.
ADC measures 5x per second. Fast

Capacitance measurement I never used on it.

Going back to Auto ranging after restart is good choice if you ask me,
There is no sound coming out of it.
