I'm really just editing the example code from the seller so that it will display decimal values instead far less useful int values

MT87 digital AC clamp meter — 400A AC current, 600V AC/DC, resistance, diode, continuity LDR sensor it is designed for reliableThe MT87 is a compact digital AC clamp meter built on large scale integration (LSI) technology, offering a practical all in one measurement tool for electricians, engineers, and electronics hobbyists. It measures AC current non invasively via its jaw clamp no need to break the circuit along with AC and DC voltage, resistance, diode forward voltage, and audible continuity testing in a single handheld instrument.
