The L/C meter 2B by Neil Heckt is a PIC16C622 based meter that is available as a kit, ready built, or for those who are able, can be home constructed after downloading the PIC code over the web. The kit includes a case and takes about 1.5hrs to complete. The Meter is self calibrating and is typically 1% accurate. Inductance range is from 1nH to 100mH (almost good enough for 8kHz Hi) or capacitance from 0.1pF to 1uF. A novel feature is the ability to cancel out, or zero, the effects of the test leads prior to making measurements at the lower end of the range. Measurements are made at 750kHz 60kHz or 20kHz depending on value of the unknown component. My kit was ordered over the net from Neil's base in Auburn, Washington USA and arrived in a few days. They are also available in the UK from Mainline Details at http://www.aade.com 73 David
