ISEN-ASTC-L is a service of the Association of Science-Technology Centers
Incorporated, a worldwide network of science museums and related institutions.
*****************************************************************************

We built our machine in-house. It is reasonably insensitive to visitors
(damped for short periods and also digitally filtered) as we wanted to get
good event recordings. No paper is involved - there are 3 on-screen scales.
Continuous recording is shown of last 10 minutes, last 24 hours and the last
'event' (1 hour)- this can be also be selected from previous saved events by
floor staff.
