·Handmade, the appearance of the right side is overly cautious.
·True four-wire 1KHz AC sinusoidal battery internal resistance meter 0.00001 ohms-200 range.
·It can measure plumbic acid, lithium ion, lithium polymer, lithium iron phosphate, alkaline, dry battery, nickel hydrogen, nickel cadmium, button battery, etc.
·The ZR function measures below 5 ohms, and the internal resistance is more accurate.
