LCR-7000 Series Precision LCR Meter

The GW Instek LCR-7000 Series is a benchtop precision LCR meter with a 5-inch touch display, measuring passive components from 10 Hz up to 300 kHz with 0.05% basic accuracy. It shows up to four parameters at once, sweeps two parameters against frequency, applies an internal ±5 V DC bias, and sorts parts into 9 BIN + 1 AUX for incoming inspection and production. Five models cover maximum test frequencies of 2, 20, 100, 200 and 300 kHz.

LCR-7000 model lineup

All models set frequency continuously within their range (±0.01%, 4-digit resolution) and share the same accuracy, test signal, bias, sorting and interface specifications.

Key specifications

Touch operation and frequency sweep

The 5-inch touch display shows setting conditions, the primary and secondary results and two monitor parameters on one screen, and GO/NoGO mode adds a PASS/FAIL verdict. The sweep function plots two parameters against frequency, so you can observe how a component’s characteristics trend across the band or check a specific frequency point. The 10-step list mode checks fixed frequency, voltage and current points in one cycle.

Bias, ALC and correction

GW Instek provides Auto Level Control (ALC) to meet the test-voltage requirements of MLCC measurement. The internal ±5 V DC bias covers bias-dependent capacitors; for higher bias, GW Instek offers the LCR-16 ±45 V DC bias voltage box and the LCR-17 ±2.5 A DC bias current box as factory options. OPEN/SHORT correction across the full frequency range or at a spot frequency removes fixture and lead parasitics.

Sorting and system integration

The Handler interface and the 9 BIN + 1 AUX comparator connect the LCR-7000 to a component sorter for production screening. RS-232C, USB Type-C and LAN carry SCPI commands for automated test, and GW Instek provides PC software for logging results. Test fixtures include the LCR-06B Kelvin clip lead (standard accessory), the LCR-05 axial/radial fixture, and the LCR-08A and LCR-15 SMD fixtures. The GRA-459 kit mounts the meter in a 19-inch 2U rack.

Applications

• Passive component characterisation in R&D and engineering test.
• Incoming quality inspection of capacitors, inductors and resistors.
• Production sorting through the BIN comparator and Handler interface.
• Power magnetics: inductance, DCR and frequency sweeps, with DC bias current through the optional LCR-17 box.
