4. application methods 1. before the primary use, should first do the thermostat powersource plug with the avonmeter a time of security check, keeps off oneof with survey resistances, measures the plug to be photogenic,center, mutually between whether has short-circuits or the insulationundesirable tendency. 2. acts according to the regulations to join the distilled water(water level to lap approximately 30-43 millimeter) to put through thepower source plug the power source, opens in the control box the powerswitch and the electric pump switch, causes in the trough the watercycle convection. 3. adjustments constant temperatures water bath to hypothesistemperature. Supposes the room temperature is 20 ℃, wants toestablish the experimental temperature is 25 ℃, its adjustmentmethod as follows: First turns on lathe the mercury contactthermometer upper extreme spiral adjustment hat the fixed screw, thengyrates the magnetic spiral adjustment hat, causes the temperature toinstruct the nut is located probably is lower than wants to establishexperimental temperature 2~3 ℃ place (for example 23 ℃), opens theheater switch to heat up (for frugal heats up time, best fills intocomparatively needs constant temperature temperature approximately lowseveral hot water), if the water temperature and the hypothesistemperature difference is bigger, may first use the high efficiency toheat up (on board heater switch to be located "passes" position), whenthe water temperature approaches the hypothesis temperature, changesto the low power to heat up (on board heater switch to be located"heats up" position). Gazes at the thermometer the reading, whenachieved when 23 ℃ about, gyrates the magnetic spiral adjustment hatonce more, causes the electronic contact and the mercury column was atjust puts through with the separation condition (when constanttemperature indicating lamp Ming Shimie). This time must slowly heatup, reaches 25 until the temperature ℃, then tightens locks thescrew.
4. like needs to use is lower than when the environment roomtemperature to be possible to use on the thermostat therefrigeration, but sur- and thermostat same electrically operatedwater pump enters the cold water with the rubber leather hose from thecondensation tube the mouth introduction to in therefrigeration, simultaneously adds on the rubber pipe,controls the cold water the current capacity, inducts therefrigeration with the cold water generally only to be able to achieve20-15 ℃ between and must shut off the electric heating switch. 5. thermostats heated up well select the distilled water, is sure notto use the well water, the river water, hard water and so on waterseepage, after still used the running water to have each time to usethis inside and outside carries on the clean, prevented the tube wallagglomeration 水垢 affected the constant temperature sensitivity. Fifth, constant temperature water bath sensitivity curve plan 1. principles Many physical chemistry data determination all needs under theconstant temperature. Wants to control the temperature, passes thecommonly used following two methods: One, realizes usingtransformation temperature, two uses the electronic control system,carries on the automatic control to the heater or the refrigerationactive status, realizes the constant temperature goal. This experimentuses the constant temperature water bath through the electronic relayto the heater automatic control, realizes controls the warm goal. Whenthe constant temperature water bath when the quantity of heat toreason and so on outside proliferation causes the system temperatureis lower than supposes the definite value, the relay forces the heaterto heat up, when the system achieved once more when hypothesistemperature, the heater stops heating up. Like this starts once again,may make the system temperature to maintain constantly in the certainscope. The ordinary constant temperature water bath structure is by the bathtrough, the thermometer, the mixer, the heater, the contactthermometer and the relay and so on partially is composed. 2. data processing This experimental digital Beckmann thermometer surveytemperature, each 30 seconds record a time of value, altogether recordfor half hour, 61 data. Divides two lines of or two row inputs it withthe corresponding time, like first line of input time, second line ofinput temperature. After the input finished, designated all data,choose "the insertion" the center "the graph", or single-clicks in thetool fence "the graph" the mark. Appears a dialog box, the choice "thestandard type" the center "the XY scatter diagram", in appears in thedialog box under the choice chart first line of second, namely a beltdiagram of curves, single-clicks again "completes" then. In right strikes, the choice "the graph option", may sectionout the graph name as well as the coordinate axis representative'smeaning and the unit, but also may choose the mesh lines the form.Right strikes nearby two coordinate axes, may adjust the coordinateaxis the scale division, the typeface size and so on. Because quite issimple, not in detail introduced in here. Discovers peak T2 and most low point T1 on the chart, the sensitivityformula is S= T2 - T1/2. See T2 =35.212 from the data and the graph,T1=35.133, S= T2 - T1/2=0.0395.

5. Relay relay with the heater and contact thermometer connected to play a role in temperature control. Laboratories have used the Relay Relay tubes and transistors Relay. Constant temperature water bath to measure the quality of good and bad, hot water can be used to measure the sensitivity. Usually measured by the maximum temperature and minimum temperature difference between the value of the numerical half to show its sensitivity. 4. Use one. Before the initial use, the thermostat should be given the power plug Multimeter used for a safety inspection, one of the measuring resistor block. Plug compatible volume, medium, whether between short circuit or insulation ill. 2. In accordance with the regulations by adding distilled water (water from the cover of about 30-43 mm) to the power plug connected to the electricity. open the control box on the power switch and electric pump switches, so that the water cycle convection tank. 3. Adjust to the hot water temperature setting. Assumed room temperature to 20 ° C, wishes to set temperature 25 ° C, the regulation is as follows : Rotary first open contact with the mercury thermometer adjust the top screw caps lock screws, and then rotating magnetic screw cap regulation, Nut instructions so that the temperature at about wishing to set below the experimental temperature 2-3 ° C (such as 23 ° C), Open heater switch heating (heating time for the savings, preferably on different machines than the required temperature thermostat a few degrees lower in water), If the water temperature and the temperature difference between larger, High-power ahead with heating (instrument panel heater switch in the "links" position), when the water temperature close to the temperature setting, switch to low-power heating (instrument panel heater switch in the "heat" position). Watching the thermometer readings, reached 23 ℃, again rotating magnetic screw cap regulation, make contact with the mercury in just connected and disconnected state (light at the prescribed temperature when eliminate). At this point slowly heating until the temperature up to 25 ° C, then tighten the screw lock. 4. For use environment below room temperature thermostat can be used on a condenser tube cooling, can be applied and thermostats same electric water pump to a tube with a rubber tube into the condensate from the mouth to introduce within the refrigeration condenser tube and rubber hoses in the tubes add a folder to control the flow of cold water, Introduction cooling with cold water can only reach between 20-15 ° C and keep electric heating switch turned off. 5. Heating thermostat, preferably distilled water and not to use well water, river water and springs and other hard water. still have to use tap water after each use this for internal and external cleansing to prevent the accumulation of Wall furring affect temperature sensitivity. 5, hot water sensitivity curve of a drawing. Principle of many physical and chemical data are measured in constant temperatures. Want to control temperature, usually with the following two methods : First, the use of phase change temperatures to achieve the second is the use of electronic control system, of the heater or cooling for the state automatically adjusted to achieve the temperature goals. The experiment used by the hot water heater on electronic relay automatically adjusted to achieve the purpose of temperature control. When the hot water for heat outward proliferation caused the temperature below the set value, the relay forced heater heating, When the system again to set temperature, heater stop heating. This cycle, we can make certain temperature within constant. Ordinary hot water from the structure of the bath, thermometers, blenders, heater, thermometer and relay contacts and other components. 2. Experimental data processing of the Digital Beckman thermometer to measure the temperature every 30 seconds a numerical mind, A total of mind for half an hour, 61 data. With its counterparts in two hours or two firms to import, such as the importation of the first line, second line input temperature. Input has been completed, all data selected, choose "insert" the "table", or click the column "chart" symbol. A dialog appears, choose the "standard type" of the "XY plot" in the dialog that appears, choose the first plan under the second, or a bit of curve, and then click "completion" can be. Right click on the blank space, and choosing "Chart options," we can chart shows the name and on behalf of the axes of meaning and units can also choose the grid format. 2-axis in the vicinity of right-click, can adjust the axis coordinates of the calibration, font size. As relatively simple, here is not the details. On maps to identify the highest point and the lowest point T2 T1, sensitivity calculation formula for S = T2-T1/2. From the data and drawings seen T2 =35.212, T1=35.133. S = T2-T1/2=0.0395.
