Firmware and source code for the Multimeter Checker/Calibrator [0410722A/B]
The PIC16F1459-I/SO microcontroller firmware (HEX file) plus the C source code and MPLAB X project for the Multimeter Calibrator/Checker.
RevB, 8/7/2022: this revision has changes that prevent some terminal programs (including PuTTY) from throwing an error when trying to connect to the virtual USB serial port. Tera Term was not affected by that problem.

Complete kit for the Multimeter Checker
A set of all the parts specified in the parts list of the Multimeter Checker project, including the PCB and all onboard parts.
The microcontroller is supplied pre-programmed. SMD LEDs are included as they are a better match the other components, which are mostly surface-mounted.
Note: photo shows fully assembled kit.
