Test equipment Shed Workshop – Saturday 9 March

On Saturday 9 March a shed workshop was held at the QTH of Mike ZL1AXG from 1pm – 3pm on the topic of test equipment. A number of speakers gave brief presentations (Mains power analyser and Vector Network Analyser by John ZL2JPM, a logic analyser by Kenneth ZS6KEN, a digital oscilloscope and spectrum analyser by Bernard ZL2BD, a Megger by Malcolm ZL2UDF, and analogue scopes by Don ZL2BL). This included a brief description of the purpose, indicative cost and tips and tricks in using the equipment. Eleven turned up and found plenty useful in the talks.

Multimeter Shed Workshop – Sunday 10 Feb

The shed workshop on Sunday 10 February was attended by five OMs. Several weren’t able to be present due to a conflict with the Vintage Radio Society. The conflicting time will be remedied for future shed workshops.

The topic for the workshop was provided by Bernard ZL2BD – an introduction to multimeter calibration.

Our measurements and calibration errors

Those attending the workshop brought along their multimeters and these were calibrated on the spot by those attending using an averaging method. Most of us were surprised how poorly the analogue meters (including an AVO) fared, and just how well our modern cheapie (and not so cheap) digital multimeters actually did.
