Control Panel
(See the inside back cover for a recommended settings guide)
Heat On light:
Indicates that the heating element is heating up.
Set light:
Indicates that the current parameter, SP1, SP2 or SP Limit can
be programmed.
Actual light:
Shows the actual immediate internal temperature.
LED screen:
Displays the current setting or error message.
Display Set button: Cycles the user through the two programs SP1 and SP2 (SP = Set Point). Pressing "Display Set" multiple times
will navigate the user from SP1 temperature and time, to SP2 temperature and time, then to SP Limit, Actual Temperature and
back to SP1.
Up and Down arrows: Adjusts the settings for temperature and time higher and lower.
Start/Stop button: Starts and stops the instrument depending upon the temperature and time settings.
SP1 LED readout: Set Point 1 has two LED readouts on the digital display. The first readout is the temperature at which the user
wants to set the Decloaking Chamber, the second is the time interval the user wants to maintain the SP1 temperature.
SP2 LED readout: Set Point 2 has two LED readouts on the digital display. The first readout is the temperature to which the
chamber has to be cooled in order to be able to remove the slides. The second readout is the amount of time the SP2 temperature
is to be maintained before an alarm goes off. The purpose of the second alarm is a quality control that allows for standardization
between runs. It also ensures that the slides remain inside the chamber for a standardized amount of time.
SP Limit readout: The Set Point Limit is an internal circuit breaker that is set by temperature. It is an absolute limit on temperature
that cannot be exceeded or the heating element will turn itself off. For example: if SP1 is set to 125 °C and the SP Limit if set to
10 °C, the element will automatically turn off if a temperature of 135 °C is reached. This is a safety feature that avoids overheating
if there is not enough water added to the system.
Error Messages
The LED panel will display the letters “ERR” if the following technical problems occur:
• The pan is not filled with enough water, causing the heat and pressure to rise beyond normal limits
• The SP Limit is set so low that the normal temperature tolerance heats beyond the SP1 + SP Limit
• Failure of the Heat Sensor
Audible Alerts
When the chamber reaches the SP1 time or the SP2 time, the alarm will beep until the "Start/Stop" button is pressed. The temperature
and pressure should be recorded at these set points for quality control.
Display Buttons: The display buttons beep each time they are pressed.
