扫描仪在出厂开箱后及长期使用过程中，用户可以自行使用本软件对扫描仪进行重新校准，以确保扫描时获得高质量、精准的三维模型。
*为什么对相机进行重新标定？扫描仪在出厂前已经过精确标定校准。
但在使用很长时间后，或由于设备受环境变化、外力、碰撞导致相机镜头位置、角度发生轻微形变，以致设备内的原出厂参数不再适用于相机的当前状态。
此时进行扫描及三维重建的结果可能会出现精度偏差，表现为生成的模型（点云）有重叠、构网后模型表面有错层、褶皱等现象。
此时就需要以相机当前的硬件状态为基础，进行重新标定（校准），重置相机内部参数。
适用产品Revo Calibration软件目前仅适用于对POP 2扫描仪（USB有线连接方式）的标定校准，后续将扩展支持更多同系列扫描仪。

Traditional methods of curing use medium or long wave infrared. Medium and long wave infrared light cures from the outside in —which can trap solvents or only cure the surface —leaving coatings wet on the inside. Short wave differs from these other methods by penetrating the applied coating and heating the substrate beneath, forcing all of the solvents out and resulting in a uniform and complete cure. Since it works from the inside out, REVO can cure up to three full coats of a product in one curing cycle with no need to cure between coats. Additionally, the infrared technology works on nearly all substrates including steel, aluminum, fiberglass, plastic, carbon fiber, etc.HANDHELD UNIT DIAGRAMHeat ShieldMain Power Switch Parameters DecalInfrared BulbHandle10 Amp at 110 VoltHANDHELD UNITSPECIFICATIONSPlug the unit into a 110V outlet rated for at least 10 amps.Flip the power switch to the on position.

3-WAYFLEX LEVELLIQUID LEVEL SWITCH OPERATION MANUALOMP# LS-3 – 5/19 1.0INTRODUCTIONThe Ruelco Model 30C2 (2” NPT Mount)/31C2 (Flange Mount) 3-way pneumatic liquid level switch is typically mounted directly into a tank or vessel or in an optional external cage (See Figures 1,2). Horizontal or hang down displacer elements are available. This displacer operates a pneumatic valve when a liquid in a tank or a pressurized vessel reaches a predetermined level. The operation mode, as a high or a low level sensor, is selected by rotating the valve body 180 degrees.FIG. 1TYPICAL MOUNTING OF MODEL 30C2LEVEL SWITCHESFIG. 2MODEL 30C2 SHOWN INMODEL 3C01 EXTERNAL CAGE 2.0OPERATION (See Fig. 3)When in the non-tripped condition, the3-way pneumatic valve is configured asa normally open valve when set for highlevel detection and as a normally closedvalve when set for low level detection.When used as a high level sensor, thevalve will allow air flow from inlet tooutlet when the liquid is below thedisplacer. When liquid contacts thedisplacer, the valve will block the inletpressure and vent the outlet pressure.When used as a low level sensor, thevalve will allow air flow from inlet tooutlet when the liquid is above thedisplacer. When liquid no longercontacts the displacer, the valve willblock the inlet pressure and vent theoutlet pressure.Because of the balanced design of thevalve, variations in instrument pressurefrom 5 to 50 PSI will have little effecton level switch performance.The switch senses a change in thebuoyancy of a displacer assembly insidea pressurized or unpressurized vessel.To transmit the buoyancy change, apivoting action is used. The I.D. of thecone contacts the pivot attached to thepush rod and valve body. The o-ring(provides a pressure tight seal betweenthe body and the shaft of the coneprotruding through the o-ring. Pressurein the vessel, if any, acting on the shaftof the cone, forces the cone against thepivot point on the valve body. Theposition of this point, at the center of theo-ring, allows the displacer assembly tomove up or down.2.1HIGH LEVEL OPERATION(NORMALLY OPEN)As the liquid level rises and begins tocover the displacer assembly, thebuoyancy in the liquid reduces thecounterclockwise rotational force on thecone. At some point, the spring willexert a greater clockwise rotational forceand cause the cone to push the valvestem downward, and act on the push rodand 3-way valve. This allows thepressure present at the outlet to ventthrough the weep holes in the valvebody while blocking the inlet pressure.2.2LOW LEVEL OPERATION(NORMALLY CLOSED)As the liquid level falls and begins touncover the displacer assembly, itsbuoyancy in the liquid increases thecounterclockwise rotational force on thecone. At some point, the displacer willexert a greater clockwise rotational forceand cause the cone to push the valvestem upward, and act on the push rodand 3-way valve. This allows thepressure present at the outlet to ventthrough the weep holes in the valvebody while blocking the inlet pressure.NOTE: THE VALVE CAN BE USEDWITH OPPOSITE FUNCTION IFROTATED 180 DEG.3.0INSTALLATION3.1 EXTERNAL CAGE TO VESSELIt is suggested that the level switch beinstalled in an external cage formaintenance and testing purposes. Onerecommended piping system formounting an external cage to a vessel isshown in Figure 1. The valves aboveand below the cage are required fortesting and maintenance purposes.If a cage with butt weld connections isused, the level switch should beremoved from the cage before welding.This will prevent weld sparks fromdamaging the displacer assembly.Remove the switch from the cage as perinstructions in Paragraphs 5.2.1through 5.2.2 of the FULLDISASSEMBLY section of this manual.After welding, install the level switch asper instructions in Section 3.2,INSTALLING LEVEL SWITCH INCAGE.If the cage has threaded or flangedprocess connections, the level switchdoes not have to be removed beforemounting the switch to the vessel. Cageswith 1” NPT process connections maybe installed on the vessel with 1”, ¾”or ½” O.D. piping.CAUTION: Be sure the pressurerating of all valves, pipe and pipefittings meets or exceeds the workingpressure of the vessel on which theyare to be installed. Adequate supportfor long pipe runs should be providedto prevent excessive vibrations of thelevel switch.It is recommended that external cages beinstalled with the process connections asclose to vertical and the cage length asclose to horizontal as possible. This willinsure the proper liquid flow into andout of the cage.3.2LEVEL SWITCH INSTALLATIONBefore installing a level switch into anexternal cage or mating flange, verifythat level switch is set up or theoperation required (i.e., high or lowliquid level detection). See Section 4.0,CHANGING MODE OF OPERATIONand Figure 5. NOTE: When directmounting a level switch to a tank orvessel, verify that the end displacerassembly will be at least ½” (13mm)longer than the 2” connection on whichit is being installed. (See Figure 4).TOOLS REQUIRED:A 2.125” openend wrench or a suitable adjustablewrench or pipe wrench.3.2.1Clean any dirt or debris from the 2”NPT pipe threads and the external cage(if any are being utilized).3.2.2Apply Teflon tape or other threadsealing compound to the 2” NPT threadson the level switch. 3.2.3Apply an anti-galling compound to the2” NPT female thread into which theswitch is installed.3.2.4 Screw the level switch into themounting thread and tighten with thewrench. When tight the spring cap mustbe up as shown in Fig. 5.FIG. 3CAUTION: If using a pipe wrench, do not allow the wrench jaws to contact the spring cap. Wrench forces may damage the cap and prevent the switch from operating properly.NOTE: THE SPRING CAP MUST ALWAYS BE IN THE VERTICAL POSITION AS SHOWN IN FIG. 5 FOR THE “FLEX LEVEL” SWITCH TO OPERATE PROPERLY.FIG. 4TYPICAL DIRECT MOUNTING4.0CHANGING MODE OFOPERATIONTOOLS REQUIRED: 3/16” Allen Wrench The level switch can be changed from high level detection to low level detection very easily. If the level switch is installed into a pressurized cage or vessel, the pressure does not have to be removed, but the caution in Section 4.2 should be followed closely. Fig. 5 shows the proper orientation of the level switch function markings for high and low level operation.FIG. 54.1UNPRESSURIZED CAGEOR VESSEL4.1.1 Verify that no pressure ispresent in the cage or vessel. Ifthis cannot be verified, followinstructions in Section 4.2PRESSURIZED CAGE ORVESSEL.4.1.2Block and bleed the instrumentpressure from the inlet. Removeany instrument tubing connectedto the inlet.4.1.3With the 3/16” Allen wrench,remove the four hex socket headcap screws. Rotate the valvebody 180 degrees to change themode of operation from high tolow or from low to high asdesired. See Fig. 5 for propervalve body orientation.4.1.4Replace the four hex socket capscrews and tighten.4.1.5Connect the instrument supplyif it was disconnected.4.2PRESSURIZED CAGE OR VESSEL 4.2.1Block and bleed the instrumentpressure from inlet. Remove anyinstrument tubing connected tothe inlet.4.2.2Use a 3/16” Allen wrench andremove two of the hex sockethead cap screws that arediagonally apart. Replace thetwo hex socket head cap screwsjust removed with two ¼”-20screws or bolts that are 1-1/4’ to1-1/2” long. These serve as asafety stop in the event the levelswitch has received unknowndamage. Rotate the remainingtwo screws one turn at a time,alternating between the two.The process pressure acting onthe end of the cone that isprotruding through the bodywill move the valve bodyoutward as the two screws areturned. When the valve bodyhas stopped moving, remove thefour screws completely. Rotatethe valve body 180 degrees tochange the mode of operationfrom high to low or from low tohigh as desired. See Fig. 5 forproper valve body orientation. CAUTION: THE VALVE BODY SHOULD MOVE OUTWARD 1/16” AND STOP AS THE DISPLACER ASSEMBLY CONTACTS THE BODY. IF THE PROCESS PRESSURE IS STILL EXERTING A FORCE ON THE VALVE BODY AFTER 1-1/2 TURNS, THEN STOP TURNING THE TWO SCREWS. THE UNIT MAY HAVE DAMAGE THAT WILL ALLOW THE CONE TO DISENGAGE THE O-RING AND THE PROCESS PRESSURE AND MEDIUM WILL ESCAPE THROUGH THE BODY. THE PROCESS PRESSURE WILL HAVE TO BE REMOVED FROM THE CAGE OR VESSEL BEFORE ANY FURTHER DISASSEMBLY IS POSSIBLE.4.2.3 Replace the four hex socket head capscrews and tighten.4.2.4 Connect the instrument supply if it wasdisconnected.5.0 DISASSEMBLY (SEE FIG. 1 and 3) TOOLS REQUIRED:7/16” open end wrench or adjustable wrench5/8” open end wrench or adjustable wrench3/16” Allen wrench1/8” Allen wrenchNeedle nose pliersPliersO-ring pick or small screwdriverLarge adjustable wrench or pipe wrench 5.1PARTIAL DISASSEMBLY(3-WAY POPPET VALVE REPAIR) CAUTION: ONLY THE VALVE BODY CAN BE REMOVED FROM THE LEVEL SWITCH UNIT WITHOUT DEPRESSURIZING THE CAGE OR VESSEL.
