Table 1 - Control and Display Descriptions
Pushing the switches turns the sample point on and off. The adjacent
light turns on when the point is on. The light blinks on and off when the
point is in alarm. When the point is on, the respective sample (when
sample switching) or cell signal (when sensor switching) will be
analyzed in sequence.
The removable name tag allows the sample name to be typed and
displayed through the clear pocket on the membrane switch. The
nametag is accessed by removing the front display plate.
Indicates the sample point number corresponding to the value in the
display function window.
Indicates the value of the current function (indicated by the display
function light which is on).
Indicates which function (CYCLE TIME, DELAY TIME, DWELL TIME,
ANALOG mA, LOW ALARM, HIGH ALARM or STATION NUMBER) is
currently being displayed.
These tactile feedback switches control the displays, reset alarms and
start or restart the Sample Sequencer. The DISPLAY, NEXT and
ALARM RESET keys serve a different purpose when programming
(see below).
Activates the programming mode to program new values for all display
functions except ANALOG mA. For example, new values for CYCLE
TIME or LOW ALARMS can be programmed. The arrows light up
when the programming mode is activated. The control switches
immediately above the arrows control the digit position and value when
programming. For example, the DISPLAY switch becomes the "up
arrow" function to increase the function display digit value when
programming.
When lit, indicates an analyzer system alarm.
