Are you interested in miliOhm and microHenry when measuring?
Measuring instruments Voltcraft LCR-100 and R-200 are able to convert estimation into accurate measurement and moreover, they are at a good price. Find them in our stock range.
The R-200 multimeter could almost be considered a common TRMS multimeter CATIII / 600V, but it has 3 ranges to measure the small resistances, which makes it unique: 40 Ohm, 4 Ohm, 0.4 Ohm.
In the smallest range, we find a great resolution of 0.1 milliohms (0.0001 Ohm). And thus we can, for example, easily measure various shunts, which are now often formed just by a small PCB track, or we can check wires for big currents, etc. In order to measure such small resistances, currents in tens to hundreds of mA are needed in practice, so the R200 is powered by 6 AA batteries, not a classic 9V battery, which is unable to deliver the required current and would quickly discharge.
The device is also very suitable for measuring very small currents, as both DC and AC ranges have a resolution of 0.1 uA.
LCR-100 is a typical representative of specialized LCR meters and thus actually allows measuring and verifying the parameters of these passive elements.
The LCR-100 has:
- 7 Resistance Range (up to 0.01Ohm).
- 8 Capacity measurement ranges (up to 1pF resolution), including large capacitance measurements up to 110mF (miliFarad).
- 4 Ranges for inductance measurement up to 1 uH resolution.
The measurement of resistance and capacity is with automatic or manual range selection. If the capacitor was not discharged before the measurement and there was a significant charge left in it, dSC will appear on the display, the capacitor will be discharged in a moment and the instrument will show the measured value. As a bonus, it also offers diode and continuity (buzzer) testing.
Large backlit displays with maximum counts of 11,000 allow a very decent resolution when comparing (selecting) passive components, where it is often not necessary to be absolutely accurate but to be able to compare the same two parts (the REL function is also perfectly suited for this). Automatic shutdown after 15 min. Inaction is also a welcome little thing.
