Display and operation Display Backlit graphics display with 240 x 160-pixel resolution Measured value display
– Numerical value with physical unit, also with bar graph indication in single display
– Resolution better than 0.2 % of the measurement span
– Simultaneous display of up to 5 measured values
– Flow: bar graph indication
Status display
Symbols in the display; the active status messages can be accessed directly from the measured value display Operation
5 keys (cursor cross and OK); menu-assisted operation
Concept of operation
The functions required in normal operation are operated and configured directly on the gas analyzer.
The functions which are only seldom required, e.g. during start-up, are configured offline using the configuration software ECT (“EasyLine Configuration Tool” on the enclosed CD-ROM) and then loaded into the gas analyzer. Measuring range switch-over and feedback There are three ways of executing the measuring range switchover: – Manually on the gas analyzer
– Automatically (autorange) by means of appropriate configured switch-over thresholds
– Externally controlled via appropriately configured digital inputs.
The measuring range feedback can be implemented via appropriately configured digital outputs; it is independent of the selected type of measuring range switch-over. The gas analyzer is set ex works to measuring range 2 and to manual measuring range switch-over. Limit value monitoring Limit values can be set using the configuration software ECT. The limit value signals (alarms) are output via digital outputs.
