My building was hit by lightning and my Hardy HI 2110WI, HI 2151/20WC and HI 2151/30WC won't power up anymore. I think they were damaged by a power surge. Do these units have a fuse? If so, how do I replace them?
Is it possible to set a specific tare value that cannot be changed? I need a way to lock the tare value, but still allow the operators a way to be able to re-zero the scale.
