6.4 ”TEST loop”
”TEST loop” is used by authorized laboratories for reverification of the meter among other things.
Before the meter can enter ”TEST loop” and thus TEST mode, the verification seal marked ”TEST” on the verification
cover of meter must be carefully broken with a screwdriver and the contact points behind the seal be short-circuited
with short-circuit pen type (6699-278).
We recommend that you complete your work in ”TEST loop” before starting reconfiguration via ”SETUP loop” or
METERTOOL HCW as every reconfiguration is logged in MULTICAL® 403 (only 25 reconfigurations permitted).
The meter leaves TEST mode and returns to the first reading in ”USER loop” after 9 hours (time-out), or if the user
keeps the primary key activated for 5 seconds.

The resolutions of the high-resolution registers are 1Wh and 10 ml respectively for all flow sizes. The registers can
only be reset by a total reset of the meter.
