Begin from measuring mode
Whilst in this state the measuring tube still vibrates and the measurements can come back on
line in an instant.
There is an additional standby state, 'STOP', in this case the drive to the primary head is
disabled and vibrations cease. However, when leaving STOP the converter has to return to
STARTUP before measurements can resume.
The instrument can be switched to STANDBY either by the keys on the display or by the control
input signal (see section 5.9). STOP can only be set by the keys.
To set STANDBY or STOP :
Begin from measuring mode
If STANDBY or STOP was selected the instrument goes immediately into that state.
To return to measurement, go back to Fct. 1.1.4. and select MEASURE.
NOTE:
It is not possible to change mode directly from STOP to STANDBY, as the converter must first
be switched to MEASURE to restart the primary head vibrations.
In addition to these 'standby' modes the SYSTEM CONTROL function provides a fully
automated way of switching to similar modes using either the density or temperature of the
process fluid as a control (see section 5.10).
