Question:	I need to measure down to 2uh, will this meter do that
Answer:	Lowest range on the BM4070 is 200 microhenries, with a resolution of 0.1 uH. However, accuracy degrades substantially at small inductance values. For example, my instrument reads 0.9 uH with zero test inductance (test lead length is 2 x 8 inches). With a 26 inch pair of test leads, this error increases to 2.3 uH. Thus, it's important to determine and subtract out the stray inductance of your test setup before trying to measure anything as small as 2 uH. Also, I have no precisely known inductances at values this small, so cannot say what the instrument calibration accuracy is in this range. If accuracy/precision are important, I'm afraid you're going to have to obtain a (much more expensive) lab-grade instrument, such as an inductance bridge, capable of measuring down to this level.
Question:	For l/c measurement, what frequency do this use? 100hz? 1khz? 10khz? or

Tips for not accurate measurement:

To measure small capacitance, different measurement principles and different measurement frequencies will lead to different measurement results.

The resistance component affects the accuracy, and the measurement results need to be subtracted from the data displayed before the measurement.

When measuring small inductors and capacitors, if the component feet are suitable, it is recommended not to use the test leads. Please just insert component feet directly into two rectangular jacks of LCR Meter to measure.

Product description

LCR-Reader-MPA is a fully automatic and manual multi tester with 0.1% basic accuracy with a wide selection of test functions and features including 100 kHz test frequency. When set to ‘Auto mode’, MPA automatically determines the type of component and best test parameters before measuring with high accuracy. All measurement values are instantly displayed. MPA is well suited for virtually any task involving SMT or PBC debugging. It is an exceptional tool for testing large Capactiances up to 680 mF. Electrolytic capacitors are measured at 120 Hertz with ESR measured a 100 kHz in accordance to regular electrolytic capacitor test conditions. When the device is in ‘Large Cap. Mode’ it will automatically reduce the test frequency to 25 Hertz, thus being able to measure very large caps with reasonable accuracy. An Oscilloscope mode allows to analyze voltage waveforms with frequencies up to 100 kHz on active circuit boards. This mode, while used with the LCR-Reader Kelvin Probe Connector, turns the MPA into a low-frequency probe station. Features: Grey backlit LCDFully automatic & manual LCR, ESR, LED/Diode measurements 0.1% Basic Accuracy Automatic & manual test frequencies; including 100, 120 Hz, 1, 10, 20, 30, 40, 50, 60, 75 & 100 kHz Test signal levels of 0.1, 0.5 & 1.0 Vrms Easy Open/Short Calibration and offset removal AC/DC voltage measurements up to 15 V AC/DC current measurements LED testing with 3.2 Volts Signal Generator with Sine wave up to 100 kHz Oscilloscope Transient Voltage up to 100 kHz 100 Ohms Signal Source Resistance Displays active & reactive impedance components Gold-plated test leads 1 oz. weight Li-Po battery & micro-USB charging port Handles components to 0201 size 4-way joystick navigation button

User questions & answers

Question:	Says esr meter , but i do not see that , even in the instruction of menus , there is no esr setting. so why does this claim to do esr
Answer:	LCR-Reader MPA is the only tweezer-meter that does ESR measurements the way it should be done: Capacitance is measured at 120 Hz and the ESR at 100 kHz. Here is a fragment of the LCR-Reder-MPA Manual Page 9: https://lcr-reader.com/LCRMPAmanual.pdf 7.1.1 Measurements When the measured component is connected to the test leads, the screen displays information depending on the component and the selected settings in the R-L-C-D mode menu. In automatic mode, measurement of capacitance larger than 0.9 μF by default is made at 120 Hz, while ESR is measured at 100 kHz. In this case the display looks as follows. The frequency is not shown on the screen, but two additional numbers are displayed indicating the capacitor parameters described below.
Question:	What is the smallest capacitance it can measure? 100's of pF
Answer:	Less than 1000 pf, the accuracy is not that great. I was able to measure 100 pf with ± 10% accuracy, which is acceptable in most of the applications.
Question:	Can this meter read down to the lower microhenry range? (uH) vs the millihentry range (mH) I cant figure specs
Answer:	I cannot attest to the accuracy of this DMM with measuring inductances however, I just measured a brand new 1000 uH inductor and on the lowest setting of the DMM it measured 1.108 mH. I would not trust it to measure anything below a couple hundred uH however, it has worked excellently for my uses in measuring components. Can't argue with the price either!
Question:	Is a 9V battery included
Answer:	Yes.

User questions & answers

Question:	will this meter measure 60Hz at 120vac
Answer:	Yes
Question:	Does this meter measure trms ac voltages for modified sine waves or square wave ac
Answer:	Yes it does read true RMS. I verified this with my modified sine wave, AC inverter/charger that backs up my basement sump pump. It reported 123 Vac which was about right while an average reading meter reported around 96 Vac. This makes sense since an average reading meter will measure 108V for a 120Vrms true sine wave. so it is calibrated 11.1% higher to report 120V. For a 120Vrms modified sine wave, the average reading AC meter will read 85V and report 95V.
Question:	What kind of test leads come with it
Answer:	It is a CATII grade leads I believe that can stand with the voltage...
Question:	I need to test the maximum current while servos are moving but the numbers change too fast. Does this have max/min function

User questions & answers

Question:	Can this be used to safely slowly discharge the capacitor of a microwave without any sparks
Answer:	No
Question:	how well does this work on induction loop testing
Answer:	The DM4070 LCR meter is not for induction loop testing. Induction loop equipment is used to transmit signals to receivers by induction. The DM4070 LCR meter is for measuring the inductance of wire coils, chokes, or transformers. The meter could be used to measure the inductance of the transmitter coil but it is not designed to transmit any signal to be measured by a receiving device.As a side note, I have found the meter to be quite accurate in Inductance and Capacitance measurement. It does exhibit erratic readings if the battery is weak. I have calculated the permeability of transformer cores with the inductance measurements and have been very pleased with the results.
