Safety Terms and Symbols Terms appear in this manual: ___________________________________________________ WARNING. Warning statements identify conditions or practice that could result in injury or loss life. ___________________________________________________ CAUTION. Caution statements identify conditions or practice that could result in damage to this product or other property. Safety Symbols Connect it to safety earth ground using the wire recommended in the user’s manual. High voltage danger The symbol on an instrument indicates that the user should refer to the operating instructions located in the 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, do not use the probe under the condition that the voltage between either input lead or earth is above 1000Vrms CAT III. This voltage rating applies to both probes and both settings 1/10 & 1/100 (TT-SI 9001) and 1/20 & 1/200 (TT-SI 9002). 10 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 MEAUSREMENT 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/60mA or regulated 9VDC/40mA mains adaptor or power lead. 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. 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. 11 4. Installation a. Simply plug-in the BNC output connector 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 or enter the batteries, then turn it on. c. Select the proper attenuation ratio. When measuring signals below 70V, switch the attenuation ratio to 1/10 (TT-SI 9001) or 1/20 (TT-SI 9002) in order to get higher resolution and less noise ratio. Otherwise, set the attenuation ratio to 1/100 (TT-SI 9001) or 1/200 (TT-SI 9002) when measuring signals up to 700VDC (TT-SI 9001) or 1400VDC (TT-SI 9002) 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 to 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. 5. Appearance The differential probe looks as follows. a. Output Cable The BNC output connector and an auxiliary grounding terminal b. Input Leads are connected to the oscilloscope. The 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. 12 6.
