To register the change, press the key labeled “Accpt.” To cancel the change, pressthe key labeled “Cancl.” The display remains at the TEST TEMPERATURE screen.If you accepted the change, note that the new set point is displayed at the top of thethermometer display on the FINAL TEST screen. This is the HISTARTTEMPERATURE that will be used when “START” is pressed the next time.< Idle TemperatureThe idle temperature is the temperaturemaintained by the instrument betweentests. This is used to speed testing, bydecreasing the time required to heat thesample chamber at the beginning of thetest. It can save 10 to 90 seconds of testtime if properly used. A common idletemperature value is 50 o C but any valueabove room temperature (but below150°C) can be used. Experiment to see Figure 21 IDLE TEMPERATUREwhat value is best for your application.Too high a value will cause low resultsbecause the sample is evaporating while the basis weight is being measured at thebeginning of the test.The current idle temperature setpoint is displayed after IDLE TEMPERATURE andthe cursor will be positioned at the first (most significant) digit. Use the up or downarrows to increase or decrease the digit value. Press the right arrow key to move toanother digit, and change each appropriately. When finished, move the cursor to theend digit and press the key labeled “Quit.” To register the change, press the keylabeled "Accpt." To cancel the change, press the key labeled “Cancl.” The displayremains at the TEMPERATURES screen. If you accepted the change, note that thenew set point is displayed at the upper and lower end of the thermometer display onthe FINAL TEST screen. This is the idle temperature that will be used after“START” is pressed the next time.28
Start Temp ControlThe START TEMP CONTROL preventsa test from starting if the chambertemperature is more than two degrees(2°C) hotter or colder than the IDLETEMPERATURE. This feature canimprovethe standard deviation of resultsof some temperature sensitive materials.When this feature is enabled (on), analarm will sound when the chambertemperature is correct.Figure 22 START TEMP CONTROLIf “START” is pressed when the chamberis too hot, the following message will be displayed: CHAMBER TEMPERATUREIS HIGH. Open the lid and wait for the alarm.If it's too cold, this message appears: CHAMBER TEMPERATURE IS LOW.Leave the lid closed and wait for alarm. When the TEMP CONTROL is disabled(off), a test can be started at any temperature.! ENDING CRITERIAEnding criteria are the rules used by theinstrument to automatically end a test.This feature makes it unnecessary for theoperator to monitor the analyzer while it isperforming a test.Change the ending criteria from the EDITTEST PARAMETERS menu using the up Figure 23 ENDING CRITERIAor down arrow key to move the selectorbar to the ENDING CRITERIA option and press the key labeled “Selct”. Thisdisplays the ENDING CRITERIA menu.END TEST ON PREDICTIONThe test will end when the predicted final valuemeets certain criteria.END TEST ON RATE The test will end when the weight loss rate falls below aselected value.Highlight the ending criterion to be changed and press “Selct.”29
