Brand Name:icchipcn.com
Condition:New
Type:Voltage Regulator
Model Number:SIRI-210
2022 New Edition !!!
VI curve tester 210 professional version (mini version) voltage is adjustable, repaired the same BUG on the market, more powerful; it needs to be used with an oscilloscope.
4 levels of voltage adjustment:0.6V; 4V; 8V; 16V;
3 levels of frequency, A channel, B channel; A + B two channels are displayed at the same time, B channel can be moved, automatic scanning function;
Square wave trigger signal (SWT)
This instrument cannot be charged for measurement, especially the high voltage on the main capacitor of the switching power supply, which will damage the instrument, so discharge measurement is required!
Can be used at the same time, also can use 1 channel,
"ALT" is 2-channel simultaneous measurement,
The black knob that separates the two curves.
Curve movement | Scan function | True dual channel | Simultaneous display | Program control | Internal resistance | frequency | Voltage | power supply | other functions | shell |
Yes | Yes | Yes | Yes | Yes | 4 | 4 | 4 | External 24V | Professional Edition | Plastic case |
This instrument is used with a dual-channel oscilloscope with XY function, no special requirements, please contact if you are unclear.
VI curve analysis is also called ASA,It does not involve the circuit principle and does not need the circuit to be in working condition, so it can be used for fault detection of the circuit board without drawings and data, which is out of the equipment (without online testing);
absoluteCan not be charged and measured for undischarged capacitance,due toThere is no need to power up the circuit board, and the circuit board is relatively safer.Does not involve the function of the components on the circuit board, so no matter what type of components the circuit is composed of, digital, analog, mixed digital-analog, known functions, unknown (such as dedicated, programmable), etc., can be tested?It is tested on a circuit-by-circuit node (device pin), and is basically not limited by the packaging of components on the circuit board. Since a single device can be regarded as the simplest circuit board circuit, ASA technology can also be used to detect the quality of large-scale, complex or integrated devices with unknown functions. In fact, due to limited conditions, ASA is the only way for many users to detect such devices. In addition, when ASA is used to detect the function of discrete components, it is also convenient and intuitive.
VI and multimeter resistance method types, but the multimeter resistance file voltage is low, and this instrument uses AC signals to excite the circuit nodes, because the amplitude and frequency are adjustable, it can be excited by the amplitude close to the working voltage, and the measured graph is more realistic , After comparison, the faulty node can be found. Due to the limited current applied to the components, this technology will not affect or destroy any components. ASA has many advantages. It has been proven to be a fast and effective fault diagnosis technology! ! !
1. Use the provided BNC cable to connect to the XY of the oscilloscope according to the mark.
2. SettingsVertical sensitivity2V/div,Horizontal time base5MS/div (digital oscilloscope needs to adjust the time base according to different frequencies, and the horizontal line will be displayed as dots if it is not adjusted),triggerIf the curve is displayed as a 45-degree line, select another trigger channel.model: X-y
3. Select low resistance, low frequency, connect the test pen, adjust the horizontal position so that the open horizontal curve is on the horizontal cross axis, short the test pen, the screen will display a vertical line, adjust the vertical position so that the vertical line is on the vertical cross axis.
4. The machine has 4 internal resistances and 4 frequencies to choose from. The internal resistance and frequency indicator lights selected by pressing the button will light up. Press the channel key, it will flash on A, B, and A/B, which is dual channel.
5. For other detailed VI internal resistance, frequency selection, and curve definition, please see the email. TSH-210 is a foreign product manual, or it can be said to be a textbook, I suggest you read it carefully.
6. The choice of internal resistance is very important. Inappropriate internal resistance will cause the curve to show an open circuit or short circuit curve. The most sensitive one is the 45-degree curve. For the combined curve of resistance, diode, capacitor and inductance, try to make the combined curve into 45 angles.
There are many examples of the effect of TR-210 manual on internal resistance, please read it carefully and understand!The internal resistance is like the resistance file of a pointer multimeter. You use the R1 file and measure the large resistance with the needle on the far right side. The resistance of 10K and 20K is the same. It is a horizontal line on the VI curve. You cant distinguish it. Use large internal resistance to measure. The small resistance, the pointer is on the far left, is a vertical line on the VI sutra, and you can't separate it. This instrument has 4 levels of internal resistance, which is set based on the experience of major domestic manufacturers. It has a different effect from those instruments that only have 1 level. You only know after using things.
