4.1 Switching the Unit On/Off
Having ensured all cable connections to the
UVD 170S/340S
, the unit can be switched on via
the power switch on the rear of the unit.
Please note:
The deuterium lamp is
not
automatically switched on. Lamp on/off is
performed by CHROMELEON
TM
. For optimum results, the lamp should
be switched on at least 30 minutes prior to analysis.
Please note:
After the Lamp off command, allow 5 minutes before switching the
deuterium lamp on again. Otherwise, the lamp becomes too hot and could
be damaged (message "Lamp too hot..."). In the event that the PC is
switched off, or the connection cable to the
UVD 170S/340S
is
disconnected, the deuterium lamp is automatically switched off.
Important:
Prior to connecting or disconnecting the
UVD 170S/340S
cable to the PC,
the unit must be switched off! Ensure that the connectors on the
UVD 170S/340S
and on the PC are inserted evenly and that they are
correctly locked into place via the latching devices on both sides.
4.2 Status LED on the Front Panel
When the detector is switched on, the status LED on the front panel indicates the current
