Why is the top section of the display not showing on the H5CN-[][][]M/H7CN-[][][]M Counter?


If a power interruption to the Counter occurs for 10 minutes or longer with the battery disconnected, errors will occur in the count value and display, even if the power recovers. Make sure a battery is connected to the Counter if the model has the suffix -M (backup function for power interruptions).

Any battery supplying 3 V can be used, but the data backup time depends on the capacity of the battery.
