Siborg has released their LCR-Reader-MPA Bluetooth Data Acquisition Tool with Logger program.
The LCR-Reader-MPA Bluetooth Data Acquisition Tool connects to PC and Android over a Bluetooth connection and allows users to remotely record measurements values in real time.
To use the LCR-MPA-BT Logger program, simply connect the BT dongle to the PC, turn on the MPA and only then start the program. The program will show that the device is connected and begin mirroring what is on the display in the program – showing the main impedance value, secondary value, signal test level, test frequency level, and equivalent circuit. There are also clickable parameters on the program’s main display for changing quick settings – frequency, test mode, etc.
The main feature of the program is the Pass/Fail assessment feature. Users are able to set custom profiles for each component in a predefined list (such as BOM). Users also set the desired values and test settings for the measured components. When testing, the main display on the program will turn red if the measured component does not meet the desired specs. The recorded values are marked red in the ‘Test’ column for fails, and green for pass.
There are two test modes: Single Component Test and Multiple Component Test. Single Component Test is best for testing the same type of component mutiple times. Multiple Component Test is best for full PCBs that have a range of different components with varied values. Users can set the name and the desired values for each component in the list. All measurement values, for both modes, can be exported to Excel.
Siborg is offering up to 30% off on many of their test devices, including LCR-Reader-MPA, LCR-Reader and Smart Tweezers devices. The sale is available in the LCR-Reader Store and Amazon sales channels. The sale runs from August 10 to August 31st at 11:59 EST.
Siborg took LCR-Reader-MPA to Nepcon Asia to show off their line of LCR-Reader multimeters with a focus on the MPA devices. Their newest business partner, AI-Rox Polytoronics, representing Siborg in China.

“There was a definitely a buzz from the audience. People were excited about fast and accurate measurements, no set-up and was also mentioned a lot. When we started presenting the device and mentioned that there would be a Bluetooth model in the future, people really got excited. Major manufacturing companies from Shenzhen were there and spoke highly of the ability to remotely record test measurements in real-time. This is a very practical ability for quality control.” says Director Michael Obrecht
Siborg System Inc. has added a Ring Coil Tester to their line of testing equipment for use with the LCR-Reader line of multimeters.
Basic inductor or coil tests can be done using any LCR meter, like LCR-Readers. When testing, if the device shows any continuity or reading this shows that the coil winding is not destroyed. Often, the coil reading may show a slight deviation in values that is only detectable by knowing the exact original values of R or L. If there is one or a few turns of the winding that have short, the values would only show a slight variation.
Using the Ring Test method is a proven accurate method of finding short turns in a coil. This method has been used for repairing old-style audio-video equipment that employ flybacks, deflection yoke windings, motors, chopper transformers, main transformers, VCR video and other magnetic heads.
The Ring Test Method is based on the theory that if a faulty coil or transformer has shorted turn(s) in one of the coils, the Q-factor of the transformer is drastically redacted. when an impulse is applied, a faulty transformer will resonate with a highly damped oscillation while a good one will decay graduall.
When connected to a high quality capacitor across one winding of the investigated device and a pulse is applied to the parallel resonant circuit, the waveform across the resonant circuit will produce a decaying oscillation. It will do this for at least a few cycles if the coil is good. The oscillations will be strongly damped and only complete one or two cycles if there is a shorted turn in any of the magnetically coupled coils of the device. A short turn can also be applied, if possible, to compare the behavior with and without the short turn. If no change is detected, there must be a shortened turn in at least one coil.
To use with LCR-Reader-MPA, connect the Ring Coil Tester using the micro-USB port on the device and connect a coil by the hook connectors. Set the MPA to “winding turns” in the menu. The display will show the excitation response from the coil. The figures below shows the difference between a good or bad coil. The shorted turn is connected and displays a significantly higher dissipation factor and therefore a fewer number of oscillations following the impulse on the coil.
Siborg presented the LCR-Reader-MPA at Nepcon Vietnam to an enthusiastic audience. The devices’ capabilities were well received and the booth had many visitors.
Nepcon’s visitors were impressed by what LCR-Reader-MPA can do. THe booth saw may visitors, many showing interest in the whole line of LCR-Reader, including the flagship device. The LCR-Reader line was created in 2014 as a budget alternative to the Smart Tweezers line of devices. The first model only offered a 0.5% basic accuracy and automatic measurements; users are able to change the test mode but not much else. Siborg released LCR-Reader-MP in 2017 as a bridge between LCR-Reader and Smart Tweezers. The MP offered a 0.1% basic accuracy and a range of features that rivaled the Smart Tweezers devices.
“The crowd was excited,” says the Director of Siborg, “the booth saw many visitors, many who mentioned they were very interested in the devices abilities. Among the visitors were many representatives from world leading companies including Toyota, Samsung and Panasonic. The announced Bluetooth model also attracted a lot of attention. The ability to save time, not only with quick and easy measurements, but also by remotely recording the values.”
LCR-Reader-MPA is offers the highest basic accuracy of 0.1% out of all Siobrg’s devices. It also offers a wide range of test features, including 100 kHz test frequency level, oscilloscope mode, LED/diode testing and more.
Siborg now offers a Bluetooth enabled model that can remotely send measurement values to PC or Android device. The measurement results are recorded in a comma-separated string of values and are instantly sent in real time to software, such as the LCR-MPA Bluetooth Logger program or NI LabView. The data can be saved to a database or spreadsheet for later analysis.
Siborg’s LCR-Reader-MPA will soon be getting an update which allows the device to remotely record measurement value over a Bluetooth connection. This adds an extra feature to the device, which already boasts a 0.1% basic accuracy and wide range of features including a 100 kHz test frequency, LED/diode testing, oscilloscope mode and more.
The new Bluetooth feature uses a low-energy Bluetooth connection using a dongle to PC, and eventually dedicated apps for iOS and Android. When connected, LCR-Reader-MPA will send the measurement data, including the main and secondary measurements value and test parameters are sent to the receiving software in a comma-separated string of values. The ability to automatically record values in real time is exceptionally useful for quality control and situations where recording values is crucial.
The device can work with programs such as LCR-Reader-MPA BT Logger, TeraTerm, or NI LabView. The recorded values can be saved to a spreadsheet or database for later analysis.
Siborg will be showing the LCR-Reader-MPA and their LCR-Reader multimeters to the Del Mar Electronics and Manufacturing Show at booth #233 in San Diego, California, from September 16-17 2020.
The LCR-Reader line of multimeters offer fully automatic LCR, ESR, LED/diode measurements. The devices use a powerful multimeter combined with a set of gold-plated tweezers; when the tweezers old a component, the multimeter will automatically determine the type of component and best test parameters to use with no set-up required. All measurement values, including any secondary values, are automatically available on the OLED display. The ability to test without any set-up is especially useful for component sorting and time sensitive tasks such as production lines.
Siborg published a white paper on TechBriefs about their newest device, the LCR-Reader-MPA. The paper gives insight to the devices’ capabilities and features.
The paper reviews how the device uses different measurement methods in order to produce high accuracy measurements, and the properties of operations. These operations include how the device is able to determine the type of component and test parameters to use. The paper also provides a short summary of the features and functions and an explanation how to use the Offset Removal feature.
The paper explains how LCR-Reader-MPA uses two methods of measuring capacitance using AC response method and DC charge/discharge methods. Using the AC response method allows the device to have a 0.1% basic accuracy for capacitances from 0.1 pf to 1 mF, the DC charge/discharge is more efficient in the range from 1 mF to 1 F.
The principle of operations is explained as “Voltage from the voltage source through a limiting 100 Ohm resistor is applied to the DUT connected at points A and B. The amplitude and frequency of the Test signal V are adjustable. The voltage drop on resistor Rj measured by DAj is proportional to the current flowing through the measured component. After digitizing the ADC signals the impedance is calculated according to the formula DUT impedance Z = Rj*Vau/Vaj.
For the Offset Elimination Technique is explained using the Capacitance Offset Calibration board; the dummy PCB uses holes to represent various sizes of components. Users place the tweezers’ tips in the corresponding hole to the component they are measuring and perform an open/closed calibration. The MPA will remove this value from the measured value, eliminating the value of any parasitics between the tweezers’ tips.
“Initial values of the impedance (offsets) obtained during calibration with Open and Short probes are stored in the non-volatile memory of the device and are considered in the calculation in the impedance of the measured component thus eliminating the offset due to the device internal parasitics.”
Siborg debuted their LCR-Reader-MPA all-in-one multitester at Nepcon Korea in May. The audience showed great interest in the devices availabilities to test with efficiency and high 0.1% basic accuracy.
“This was the first presentation of the new LCR-Reader-MPA. EMK Nepcon has been proven to be a great place for us to debut devices in the past and this year was no different. We heard a lot of feedback from people, mostly interested in the wide range of applications and high accuracy of the MPA” says Michael Obrecht, the director of Siborg.
Electronics Manufacturing Korea (EMK) has become a globally renowned exhibition for domestic and foreign buyers and is Korea’s largest electronics manufacturing exhibition. Siborg has debuted both LCR-Reader and LCR-Reader-MP at Nepcon in 2014 and 2017 respectively.
LCR-Reader-MPA is a different from traditional multimeters that require set-up and have long wire leads. MPA’s compact design that combines a set of tweezers with a powerful multimeter. When in contact with a component, MPA will automatically determine the type of component and best test parameters to use for the highest accuracy measurements. All measurements are done with 0.1% basic accuracy and are instantly shown on the OLED display, including any secondary values (ESR, Q, D).
