Yokogawa CA150 垂直手持校准仪说明书
Vertical Handheld Calibrator Easy-to-hold vertical body is designed to make it intuitively easy to operate, as individual functions are accessed directly by pressing assigned keys. The main body case (sold separately) is designed to make it easy to hold the CA150 in one hand.Simultaneous Source and Measurement for Process Devices In conventional calibration applications, multiple devices such as a standard generator, dial resistor and multimeter were required. Now with a single CA150 unit, it is possible to perform operation check at regular inspection and maintenance of thermocouples, RTDs and instruments, as well as maintenance and equipment diagnosis of process devices such as transmitters, thermostats and signal converters.Loop Power Supply Function It is possible to measure generated current signals while supplying loop power 24 Vdc from a two-wire type transmitter (up to 22 mA DC).Highly Accurate and Multi-Functional Source and Measurement High Accuracy: 0.02% for the source unit and 0.02% for the measurement unit Source and Measurement Functions: DCV voltage, DC mA, ohm, Frequency and temperature (thermocouple, RTD) and 24 Vdc power supply function for transmitters Memory Functions:Setting Memory This function saves/loads setting conditions. Up to 21 data items can be stored. Settings for (source/ measurement) functions, ranges, generated values/measured values as well as setting mode conditions can be stored.Data Memory This function saves source and measure values displayed. Up to 100 data items can be stored.Storage date/time, (source/ measurement) functions, ranges and generated values/measured values can be stored. Stored data can be checked on the display of the main unit as well as via communication.Multi-Functional Handheld CalibratorU H ighly Accurate Within0.02% of the DC Voltage Range for Source and MeasureU S ource and Measurementcan be Performed SimultaneouslyU V ertical Body with LargeScreen Display U L oop Power SupplyU S ink FunctionU 3 Sweep FunctionOutputs (Step Sweep, Linear Sweep, ProgramSweep)CA150CA150 shown smallerthan actual size.Specifications (Common to Source and Measurement)Communication Functions: Serial interface RS232 D-Sub 9-pin connector Memory Functions: Data can be stored and loaded in setting memory (setting data) and data memory (source/measurement).Specifications (Common to Source Specifications)Power Supply: 6 “AA” size alkaline batteries (included), AC adaptor (sold separately) or dedicated NiMH battery (sold separately)AC Adaptor: 100 to 240 Vac, 50/60 Hz, 1.4 A Output: 12 Vdc, 3 A Battery Life Conditions: Simultaneous source/measurement output of 5 Vdc/10 k Ω or more Vdc A pprox 8 Hours: When 6 batteries are used Approx 10 Hours: When NiMH batteries are used Auto Power-Off: Approx 10 minutes; it can be canceled by setting Insulation Resistance (Between Input Terminal and Output Terminal): 500 Vdc, 50 M Ω or more Withstand Voltage (Between Measurement Terminal andGeneration Terminal): 350 Vac,1 minuteProgram Sweep FunctionOperating Temperature/Humidity Range: 0 to 40°C (32 to 104°F), 20 to 80%RH (no condensation)Storage Temperature Range:-20 to 60°C (-4 to 140°F), 90%RH or less (no condensation)External Dimensions: Approx 251 H x 124 L x 70 W mm (10 x 5 x 3")Weight: Approx 1000 g (oz)Accessories: One set of leadcables for generation, 1 set of lead cables for measurement, carrying case, terminal adaptor, and 1 (spare) fuse for measurement.Conforming Standards:Safety: EN61010-1EMC: EN 61326 Class B;EN 55011 Class B Group1EN 61000-3-2; EN 61000-3-3,EN 61326CA150-STRAP-CASE, strap and accessory CA150-NIMH-BAT, shown smaller than CA150-ACC-CASE, accessory storage case with lead cables, RJ sensor, and more can shown smaller than actual size.O A c Lead cable for source (one set includes 1 red and 2 black cables) Lead cable for measurement All shown smaller* Depending on the internal settings, either ITS-90 or IPTS-68 can be selected.Temperature Coefficient: Accuracy above x (1/10)/°C.

但是,近年来学者们对带有积分边值条件的奇异微分方程正解存在性的研究还是比较少的。
奇异分数阶微分方程有着实际的应用价值，该类微分方程是如今学者们研究的热点。
因此，本文的研究有着重要的意义。
