7. Instrument set-up
These options can be adjusted by the operation software dVISION (please refer software manual).
7. 1. Clock switch
The integrated clock switch is internally connected to the input of the filter stepper. Please read the
chapter "User specific settings" how to use this feature for periodical filter movement. If the clock
switch is not used, it should be deactivated.
7. 2. Synchronized start of a measurement
Sometimes it is required to synchronize the sampling points of several instruments at different
locations. This can be done easily by the synchronized start capability of the instrument. Select the
cycle which shall executed from the cycle selection menu. Use dVISION to set the day time when the
cycle shall start. Check out if all instruments which have to be synchronized are set to the same time
base.
7. 3. Display standby
The display is switched off after a certain period to save power. The period counts from the moment
of the last touch to any of the soft buttons and may be set to a value between 1 and 255 Seconds.
8. Alert functions
Several types of alerts can arise while the unit is in operation. In parallel to the radiometric measures,
flow rate and filter contamination are monitored continuously. All alert thresholds are adjustable by
the user. It is also possible to disable one or more alerts. These settings can be done with the PC
configuration software dCONFIG.
The instrument is equipped with a signal tower (on top) with green, yellow and red lights. An acoustic
alert generator (rear) will be activated always together with the red light. Additionally to the optical
and acoustic signals, a touch button with an alert message appears at the screen. Touching the
button leads to a list containing all pending alerts. The alert list has to be confirmed by pressing the
CONFIRM button. The behaviour of the signal devices can be configured by the user for each alert
source independently. Two options are available:
