I've downloaded NI-VISA and got that working I probably don't
need to download tek-VISA.

How is the counter configured? A

How is the counter configured? Are you reading period or frequency? Are
you in "E?" (Every Result) mode, or "C?" (Continuous Result) mode? The
former should give you continuous but independent measurements, while the
latter gives heavily overlapped measurements. (For example, with a 100
