70MHZ高壓測試-差分探頭 原裝-臺灣進口 以下為技術參數 1 70MHz HIGH VOLTAGE DIFFERENTIAL PROBE USER’S MANUAL This probe is in compliance with IEC-61010-031 CAT. I, Pollution Degree 2. 1. Safety Terms and Symbols Terms appear in this manual: _______________________________________________ WARNING. Warning statements identify conditions or practices that could result in injury or loss life. _______________________________________________ CAUTION. Caution statements identify conditions or practices that could result in damage to this product or other property. Symbols appear on the product: Danger Protective Attention High Voltage (Earth) Terminal Refer to Manual 2. General Safety Summary Review the following safety precautions to avoid injury and prevent damage to this probe or any products that connected to it. Observe Maximum Working Voltage To avoid any injury, does not use the probe under the condition that the voltage between either input lead or earth is above 2500Vrms CAT II or above 5000Vrms CAT I between two inputs. This voltage rating applies to both of 1/100 & 1/1000 settings. 2 Must be Grounded This probe is grounded with the shell of BNC connector and an auxiliary grounding terminal, through the grounding conductor of the power cord of the measurement instrument. Before making connections to the input leads of this probe, ensure that the output BNC connector is attached to the BNC connector of the measurement instrument and the auxiliary grounding terminal is connected to a proper ground, while the measurement instrument is properly grounded. Use Fused Test Prods if Necessary If this probe is intended to use for measurements in circuits of INSTALLATION CATEGORY III, it should incorporate with fused test prods. Do Not Operate Without Covers To avoid electric shock or fire hazard, do not operate this probe with covers removed. Do Not Operate in Wet/Damp Conditions To avoid electric shock, do not operate this probe in wet of damp conditions. Do Not Operate in Explosive Atmosphere To avoid injury or fire hazard, do not operate this probe in an explosive atmosphere. Avoid Exposed Circuit To avoid injury, remove jewelry such as rings, watches, and other metallic objects. Do not touch exposed connections and components when power is present. Use Proper Power Source To ensure this probe function well, use four AA cells or 6VDC/200mA or regulated 9VDC/120mA mains adaptor or power leads. Do not operate this probe from a power source that applies more than the voltage specified. Do Not Operated With Suspected Failures If you suspect there is damage to this probe, have it inspected by qualified service personnel. 3 3. Description By enabling conventional oscilloscopes to display and measure in-circuit waveforms that are referenced to high common mode voltages. The differential probe extends the measurement capability of oscilloscopes in electronic power converters, inverters, motor speed controls, switch mode power supplies and many applications. 4. Installation a. Simply plug-in the output BNC connector of this probe to the vertical input of a general purposed oscilloscope or other measurement instrument, and connects the auxiliary grounding terminal to a proper ground. The measurement instrument must have a ground referenced. b. Connect an appropriate power source to this probe and then turn it on. c. Select the proper attenuation ratio. When measuring signals below 700V, switch the attenuation ratio to 1/100 in order to get higher resolution and less noise ratio. Otherwise, set the attenuation ratio to 1/1000 when measuring signals up to 7000V. ________________________________________________________ WARNING. To protect against electric shock, use only the accessories supplied with this probe. d. Using the appropriate probe accessories, connect the inputs to the circuits under measurement. ________________________________________________________ CAUTION. This probe is carry out differential measurement between two points on the circuit under measurement. This probe is not for electrically insulating the circuit under measurement and the measuring instrument. 4 5. Appearance The differential probe looks as follows. a b c a. Output Lead T h e B N C output connector and an auxiliary grounding terminal are connected to the oscilloscope. b. Input Leads T h e input leads of the differential probe connect to sprung hooks that come with the probe. c. Sprung Hooks The sprung hooks are connected safely to test points in circuits under measurement. 6. Power Leads We offer two types power leads; a. Adaptor-Lemo?0?3 Lead: For the oscilloscope whose power connector is Lemo?0?3 connector. b. Adaptor-Probus?0?3 Lead: For the oscilloscope whose power connector is Probus?0?3 connector. c. USB Power Cord: For the oscillo
