Does anyone have an HP 5316B counter? I found one on Ebay but one picture shows the Error LED on, but another pic does not (see attachments).
The manual says that the Error LED will light and show an error code, but it's not clear what it means if no error code is displayed. I'm wondering if the error LED can come on when certain buttons are not depressed. For example in the pic with the error code I do not think any function buttons are pressed.
In any case, if anyone has one of these, is there any reason to believe that the unit in the pics is malfunctioning?, according to what you see? The seller simply says its used and they have no means to test it further.
