TEST loop
The TEST loop is, for example, used by authorized laboratories for reverification of the calculator, among other
things.
Before the calculator can enter the TEST loop and thus the TEST mode, the verification seal marked “TEST” on the
calculator’s verification cover must be carefully broken with a screwdriver and the contact points behind the seal be
short-circuited. For this purpose, a short-circuit pen (6699-278) from Kamstrup A/S can be used.
It is recommended to complete the work in the TEST loop before starting a reconfiguration via the SETUP loop or
METERTOOL HCW as every reconfiguration is logged in MULTICAL® 803 (it is only possible to reconfigure MULTICAL®
803 50 times).
The calculator either leaves the TEST loop and returns to the first reading in the USER loop after 9 hours (timeout) or
if the user keeps the primary key activated for 5 seconds and manually leaves the TEST loop via the Select loop.
