totaliser is frozen. The main display will have the STANDBY indicator set and will display either

line as soon as required.
In addition, there is a ‘STOP' condition, in which the drive to the primary head is disabled and
vibrations cease. It MUST be noted that when leaving STOP, the converter has to return to
STARTUP before measurements can resume.
