New LCR-Reader-R2 Ready for Release

// August 23rd, 2021 // No Comments » // Uncategorized

Siborg’s newest device, the LCR-Reader-R2 is read for release. The new device is based on LCR-Reader-MPA, with features from the previous model and better stability for testing in-circuit measurements. The ability to switch test signal source resistance from 100 Ohms to 1.4 kOhms. The higher source resistance reduces noise when measuring small inductances.

R2 utilizes a different, more powerful MCU and therefor allows to process measurement at higher frequencies. This also allowed an implementation of additional test feature, the Analog Signature Analysis. ASA is a circuit board troubleshooting technique that uses an AC sine wave across two points of an electronic component or a circuit. The resulting waveform is displayed using current and voltage as x and y axis. This signature is compared to that of the known good circuit board or component allowing to determine the board or component health.

The R2 was supposed to initially have a 300 kHz test frequency, but after some preliminary testing, 300 kHz was too high without sacrificing measurement accuracy. The 250 kHz test frequency, along with the change in source resistance, is very important while testing small capacitance and inductances, and also while testing in-circuit.

The major differences between MPA and R2 is the removal of AC/DC current measurements, AC/DC voltage measurements up to 15 V, Frequency meter and Oscilloscope mode.

Features on R2:

  • Automatic and manual LCR, ESR, LED/Diode measurements
  • 0.1% basic accuracy
  • Automatic test signal reduction to 0.1 V for in-circuit measurements
  • Three test signal levels, 0.1, 0.5 and 1 Vrms
  • Automatic and manual test frequency, including 100, 120 Hz, 1, 10, 20, 30, 40, 50, 60, 75, 100 and 250 kHz
  • Measures components to a 0201 size (0.3 mm)
  • Parasitic offset removal using easy Short/Open Calibration
  • 1.5 oz. weigh
  • Backlit LCD
  • Displays active and reactive impedance compoennts
  • gold-plated test leads
  • NIST traceable calibration certificate.

Test Results for the First Batch of the LCR-Reader-R2 Tweezer-meter

// September 29th, 2020 // No Comments » // Uncategorized

Siborg is continually working on updating the devices in order to offer their customers high accuracy devices while still being affordable. For over a year they have been working on a new model of their LCR-Reader devices, the LCR-Reader-R2. The new model offers a basic accuracy of 0.1% and features a record high 300 kHz test frequency. The new device is going to have the ability of using adjustable 100 Ohm and 1 kOhm signal source resistance allowing for better in-circuit testing.

The new model combines advantages of past models LCR-reader-MP and LCR-Reader-MPA due to the ability of switching the test signal source resistance from 100 Ohms as in MPA to 1 kOhm as in MP. Using 1 kOhm increases the stability of measurements and works much better for in-circuit measurements. But, lower source impedance effectively increases the actual test signal applied to the component under test, thus reducing the signal-to-noise ratio in some cases.

The device will feature a new CPU, which allows for 300 kHz test frequency. This frequency also may allow to better measure sub 10 nH inductors.

The new device will have better accuracy for measuring small capacitances and inductances and in-circuit measurements due to the ability to use higher source resistance. The higher accuracy is due to the use of adjustable signal source resistance of 100 Ohms and 1 kOhms, and the higher 300 kHz test frequency.

LCR-Reader-R2 will not feature the same features as LCR-Reader-MPA;

  • Automatic and manual LCR, ESR, LED/Diode measurements
  • 0.1% Basic Accuracy
  • Automatic and manual test frequency including 100, 120 Hz, 1, 10, 20, 30, 40, 50, 60, 75, 100 and 300 kHz
  • Three test signal levels: 0.1, 0.5, 1 Vrms
  • Automatic Test Signal Reduction to 0.1 V for in-circuit measurements
  • Parasitic offset removal using easy Short/Open Calibration
  • Measures compoents to a 0201 size (0.3mm)
  • Displays active and reactive impedance components
  • Li-Ion battery and micro-USB charging port
  • 1.5 oz. weight
  • Backlit LCD display
  • Gold plated test leads

Features that are only available on LCR-Reader-MPA

  • AC/DC voltage measurements up to 5 V
  • AC/DC current measurements
  • Oscilloscope Transient Voltage up to 100 kHz
  • Frequency meter
  • Sine Wave Signal Generator

Each device comes with pre-installed set of gold-plated tips, NIST Traceable Calibration Certificate, Offset Calibration Board and hard-shelled carrying case. Other accessories include spare ergonomic bent-tips, spare battery and the LCR-Reader Kelvin Probe Connector.

New Bluetooth Data Acquisition Tool

// September 28th, 2020 // No Comments » // Bluetooth, LCR-Reader, LCR-Reader-MPA

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.

Coil Ring Tester Attachment Now Available

// September 4th, 2020 // No Comments » // Uncategorized

Siborg has begun offering a new Coil Ring Tester for LCR-Reader-MPA.

LCR-reader-MPA with Coil Ring Tester

The main difficulty for testing coils if that the LCR-meter shows almost no change in the impedance value if there is a short turn in the coil. An accurate way of finding short turns in a coil is by using the Ring Test technique. This method has been used in old AV equipment that us flybacks, motors, chopper transformers, deflection yoke windings, magnetic heads, main transformers and ore.

The coil ring method is based on Gibbs phenomenon that is a response of the system to a step excitation. When a capacitor is connected across the investigated coil and a pulse is applied to the parallel circuit. The wave form across the resonant circuit will create a decaying oscillation, with 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 could also be applied, when applicable, to compare with and without a short turn. If there is no change, there is a short turn in at least one coil. Experience and comparison with a known good device will tell you what to expect.

The LCR-Reader-MPA is connected to the Ring tester using the micro-USB plug and connected to the coil under test using the hook connectors. Set the MPA to “winding turns” in the menu. When the device is set, the screen will show the response on the display. The example below shows a dramatic difference; when a shorted turn is connected, the display shows significantly higher dissipation factor and therefore a fewer number of oscillations following the impulse on the coil.

The Ring Coil Tester Attachment is currently only available from Siborg directly and from their Chinese distributor AI-Rox in Shenzhen.
