A.3 Fuse Replacement
Different models of our company product are supplied with different fuse assem-
bly. The way to replace the fuse changes accordingly. The common ways are as
follows. Please choose the corresponding way of disassembly and replacement
based on the fuse assembly of the actual instrument.
If there are no fuse assembly on the instrument rear panel, it means that you
can’t replace the fuse by yourself. Please contact the ITECH engineer on the
condition of the same malfunction.
