Q: Getting ERR 02 or FUSE Message on LCR meters 878B and 879B
A: If the display of the LCR meter is showing ERR02 or a FUSE error message, check the internal fuse to verify that it is still operating normally. The fuse is marked by F200, located near the shielding spring on the bottom right of the back of the board near the Guard terminals. This is a SMD fuse. Replace this should remove the errors.
If error message still comes up, please contact B&K Precision using the Contact Us page on our website at www.bkprecision.com . The most common cause of this error is due to improper use of the LCR meter, or accidentally putting a charged component or static at any of the inputs of the meter. Because the meter contains very sensitive electronic components, any externally charged electrical elements can damage something internally, thus causing this error message to arise.
