Test mode
In order to access test mode the ”TEST” seal
on the back of the meter
must be carefully broken with a screwdriver and the contact points behind
the seal short-circuited with short-circuit pen type 66-99-278.
Subsequently, test is displayed.
The meter remains in test mode until the front button is activated for 5 s,
however, a time-out secures that the meter returns from test mode to
normal mode after 9 hours.
When tests are finished the seal must be re-established using a void label
size 15 x 15 mm (Kamstrup's seal no. 2008-727 can be used). The seal is
important with a view to the meter's approval and to maintain its protection
class.
