• Why is the display blank on a newly purchased H7E[]-N?
• When a single pulse only is input in the Counter, why does the Counter convert the pulse into at least two count values?

• Why does the Counter not count when the input signal is input?
• Why does the Reset Key on the H7E[]-N not function?
• What are the voltage values when the input terminals used for an NPN open-collector input are OFF and the current values when the input terminals are ON for the H7BR, H7HP, and H7EC Counters?
• What do the input conditions that are specified in the data sheet for "no-voltage input" mean?

• What is a substitute product for old H7A Digital Counter?
• When inputs CP1 and CP2 are simultaneously input to H7CX Multifunction Preset Counters when used as a dual counter, are both of them counted?
• The rate of rotation is displayed using the H7CX's tachometer function, but why doesn't it show 0 when rotation has stopped?
• When the H7ET-N's Time Counters time range switch is set to 0.0 to 3999d23.9h, what is displayed after 23.9 h?
