P-800LT Freeze Point Analyzer 

6-2 

Routine Maintenance & Service 

 

System Temperatures  — This is an informational display only. 

T1 — For future use. 

Sample — This is the temperature inside the sample cell.  

Sensor — For future use. 

Output Control — The operation of the Analyzer’s various solenoids can be checked via these menu 
items. The Up/Down Arrow keys are used to change the status. 

Sample Solenoid  — The Analyzer’s sample solenoid valve is opened when this menu 
item is switched from OFF to ON. 

Validation Solenoid — The Analyzer’s validation solenoid valve is opened when this 
menu item is switched from OFF to ON.  

Stream Solenoid — The Analyzer’s stream switching solenoid valve is opened when this 
menu item is switched from OFF to ON.  

 

NOTE: The instrument must be equipped with the validation and stream switching 
options in order for the Validation and Stream Solenoid menu items to function 
properly. 

4-20 Control — This menu item allows you to output an analog signal with which to calibrate external 
devices. The Up/Down Arrow keys are used to increase/decrease the analog signal value. 

Alarms — The Analyzer’s alarm relays will activate when these menu items are switched from OFF to 
ON. 

Cell Temperature Control — These menu selections allow you to heat/cool the detection cell. When 
heat/cooling is applied, the system temperature information should change accordingly. The Up/Down 
Arrow keys are used to change the value or status of the highlighted selection. 

PWM Load — This is the percent of maximum power applied to the heater.  

Heater — The detection cell is heated when this menu item is switched from OFF to ON.  

Cooler — The detection cell is cooled when this menu item is switched from OFF to ON.
