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

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.
