can demonstrate the size of what and surplus sky of oil mass in each jar in good time, different jars can call different jars gage table, so carry out the gage table setting and be exactly and different jars is set specifically will calls which gage table and count to be provided with and certain jar will be set exactly will import what points, key is set by selecting to count can count with the numerical key input, to count by corresponding preservation after input finishes and to come into force after key is preserved, (1) each jar count can import at most 50 points (2) count input will to preserve 7 spacings that can come into force be unit with the centimetre by preserving key after finishing, the input method of spacing is with the same remarks of input method of counting: the spacing of (1) each jar can be after selecting the input of (2) spacing to finish between the digital 1-9 will be preserved to come into force and 8 selects to be provided with by numerical key 1-8 and count and the jar of spacing by preserving key, with said method counting of all jars and spacing can be set simultaneously, count and after spacing 9 imported counting of certain jar and spacing will importing earlier before each jar input data, select enter key to import the gage table data, the effect that oil product is selected: in order better to carry out the unitarity management of each oil tank and oil product, need to select the 95# oil product to the oil product setting of oil tank, press earlier the oil product options button, select the 95# oil product by numerical key " 3 " key again, can preserve by the preservation key and come into force selecting to finish the back, alarm is meant when being provided with warning, and the alarm that is produced when satisfying alert if, the warning setting option of setting operation of specifically reporting to the police referring to 3.2.1.3; Alarm comprises that (Chinese character display alarm and audible alarm on the liquid crystal) is if be provided with oil level, water level, temperature alarming also just occurs the alarm shown in the last figure when satisfying alert if, last figure illustrates the oil level and the temperature superelevation of No. 1 jar respectively, water level is ultralow, the alarm lamp flashes with alarm sound and points out simultaneously, can check the alarm condition of other oil tanks by numerical key 1-8, can be directly can illustrate by the cancellation alarm keys as cancelling alarm sound: after by the cancellation alarm keys, perhaps chimes of doom also will continue 1-3 time can stop remarks: at the default conditions of the setting of reporting to the police or be set to represent to close warning at 0 o'clock.
