Operating the Analyzer from the Keypad
The keypad enables the operator to modify measurement units, adjust
operational parameters, and perform diagnostics. However, once the analyzer
is installed and operating normally, there should be no need to alter the
operational parameters. During normal operation, the LCD continuously
displays the measured component’s concentration, temperature, and sample
cell pressure.
The SpectraSensors keypad is shown in Figure 3–2. To activate any functions
on the keypad, press the mode key # followed by a number on the keypad to
specify a mode.
When you press the # key, the word MODE displays on the LCD. At this point,
the analyzer waits for you to press a second key.
The * key functions as the “enter” key. The analyzer saves the displayed
parameter value when you press this key. Always press * after entering a value
on the keypad (unless the entry was made in error).
If you do make an error, press the # key followed by the 1 key to return to
Mode 1 without saving.
You must press the # key before pressing a number or function
key to trigger a response from the keypad.
