: Better calibration for low-capacitance and high-resistance measurements.
Flashing the firmware on an LCR-T7 is not as simple as plugging in a USB cable. Because the onboard micro-USB port is usually wired only for charging the internal lithium-ion battery, you must access the microcontroller directly. 🛠️ Required Hardware lcr t7 firmware updated
