Review on 🔧 Neoteck Auto Ranging Digital Multimeter - Portable Case, 4000 Counts Volt Meter for AC/DC Volt Current Resistance Capacitance, Frequency, Temperature, CMOS TTL Duty Cycle, Transistor Diode by Vangele Carson

So far so good. I have used more functions but have not tried CMOS, TTL or ammeter. The voltage works well, both DC and AC. The ohmmeter, continuity, diode, frequency counter and capacitance meter are fine, but the latter can have a 10 second delay, but that's for sure. The temperature is ok, although I've only used it once with boiling water and it was wrong. The hfe functions operate at 10uA in the base, so care should be taken with this measure. I use more hfe to see if some LEDs work. Cables are a great thing, they are really practical. Comes with instructions, batteries, 3 cables and case. It was a great purchase.
