To enter a sample number: a. Depress the (N) key – a number will display. b. Enter new number (1 – 6 figures) using keypad – display will blink. c. Depress the (ENT) key to validate. 14 Start stirrer by depressing “-O-” key. 15 Start test by depressing ON key. 16 Test will end when ball drop is detected – an audible alarm will sound and display will blink. 17 Press “ALA” key to silence alarm. IMPORTANT: At test end, “ALA” key must be depressed to store data. If “OFF” key is pressed to silence alarm, data will be lost and will not be retrievable. 18 Record temperature reading from display screen. 19 Clean test components with toluene while still warm. CAUTION: Allow beaker to cool before removing from heating plate. Completed Date: Note: Prepared By: Approved By: This procedure is only valid at the time of printing.
