Siborg has released a new model in the MP line, the LCR-Reader-MPA. The device features a new design with lighter weight, easier-to-read display, and 4 way-joystick navigation button. Features include 3 test signal levels, more accurate LED testing, and 0.1% basic accuracy.
The title says it all, LCR-Reader will automatically show you all you need to know with just a touch, with no set-up required. When a component is between the gold-plated tweezer tips, LCR-Reader will determine the type of component, main impedance value L, C or R, but also any ESR value and the frequency used.
Built for Simplicity
LCR-Reader handheld multimeter is a lightweight device that can determine and test components with just a touch of the gold-plated tweezer probes. When a component is between the tweezers' probes, LCR-Reader will automatically determine the type of component and select the best test mode and frequency to use for the component. All measurements are done using a 0.5% basic accuracy and data is instantly displayed on the OLED screen. The device will show the test mode (L, C, or R), main impedance value, secondary value (ESR) and test frequency used.
Controlled by a one-button navigation, the device will cycle through the test modes with each touch. These modes include Inductance, Resistance and Capacitance, ESR (Equivalent Series Resistance) and Auto mode which allows the device to select the component type to use.
The device is powered by a Li-Ion battery and recharged via micro-USB. The 80-hour continuous battery life, bright OLED display and 1 oz. lightweight, compact design makes LCR-Reader ultimately portable and useful for in-field tasks.
The display, shown on the left, is an example of LCR-Reader during a measurement. AM shows that the device is set to 'Automatic Mode' and is measuring a 'C' Capacitor with 20.08 pF, using a 10 kHz test frequency. The value on the top of the display is the secondary value, shown as Rs, the parasitic series resistance. A battery icon indicates the remaining charge of the devices.
To verify the LCR-Reader's accuracy, Siborg sent 4 randomly selected devices to Navair Technologies, one of Canada's leading calibration facilities for NIST certifications in Toronto, Ontario. The results returned were higher than expected, with basic accuracy closer to 0.5% than the believed 1%. View the results and certificates here. New 4-wire and 2-wire Calibration Fixtures were created for LCR-Reader and Smart Tweezers devices, including older models. The calibration fixture uses 14 known components within the LCR-Reader's measurement ranges. When connected, the calibration fixture signals a different component with each button press. The measurement values displayed are compared to the actual values of the components to confirm or reject the accuracy.
LCR-Reader or Smart Tweezers ST-5S: Which Device is Best for You?
LCR-Reader is an alternative to the Smart Tweezers line of handheld digital multimeters. The tried-and-tested design of a set of tweezer probes combined with a multimeter that requires no set-up between measurements. There are a few differences between the devices, so which is best for you?
LCR-Reader was created a more affordable device, which was achievable by removing some features and LCR-Reader uses the same design as Smart Tweezers, with tweezer probes combined with a digital multimeter. Unlike Smart Tweezers, LCR-Reader is priced lower, around $200 USD, making it more affordable for hobbyists and non-professionals.
All measurements are done with a 0.5% basic accuracy, which is slightly lower than the 0.2% accuracy offered by Smart Tweezers. Smart Tweezers also offers more test signals (0.5 and 1.0 Vrms), variable tolerances (1, 5, 10 and 20%), more features including continuity and diode testing, and a semi-automatic offset removal. Smart Tweezers also uses a joy-stick navigation which allows for more customization for measurements, including the ability to change basic test parameters from the main display.
LCR-Reader is a far more stripped-down model with only LCR and ESR measurements, 0.5 Vrms test signal, and one button navigation, but these all contribute to the ability for a lower priced device.
For a better comparison between LCR-Reader and Smart Tweezers devices, consult the comparison table below. The table also outlines the features found on LCR-Reader-MPA, Siborg’s most recent device that offers more features and higher accuracy than both LCR-Reader and Smart Tweezers.
Smart Tweezers ST-5S, LCR-Reader and LCR-Reader-MPA Comparison
The Colibri is the model right between Smart Tweezers and the LCR-Reader. Built from the LCR-Reader, the Colibri offers a 0.5% basic accuracy, lower price, and easy-to-use design but allows users the ability to select the test frequency for more specific measurements. Just like LCR-Reader, Colibri is able to automatically determine the type of component and the best test mode and parameters for the component under test. The main difference between the Colibri and LCR-Reader is the variable test frequencies on the Colibri. When the button on the device is pressed, Colibri will change the measurement mode (AM, L, C, R, ESR) with frequencies of 10 kHz, 1 kHz, or 100Hz available for selection. To reset the device to the default fully-automatic mode, simply hold the button down until the display flashes. The Colibri is available for around $200, making it affordable for non-professionals. This model does not come with the NIST traceable Calibration Certificate.
