Status Mode
ELSD-A120 can be operated in two modes; STANDBY or RUN, both of
which are described below.
To display the current mode and/or select a new mode, highlight the
MODE function on the detector display. The current mode will now be
displayed on the screen. Using the arrow keys, scroll up or down until
the desired option is displayed. The detector acknowledges the
command by displaying the mode of operation in the top right hand
corner of the screen.
Standby
The STANDBY mode is the “ground state” of the detector, which is by
default initiated automatically after power on (default can be changed
using power mode, see “Power Mode” on page 33 ). In STANDBY
mode, the heaters and light source are switched off, and the gas
manifold valve is closed at power on. The STANDBY mode gives the
user a control platform in which to set-up the operational parameters
(gas flow, nebulizer and evaporator temperatures) before switching
the detector into RUN mode. The detector will default to STANDBY
mode should an error occur on the detector.
