In the other 20% of cases, you can usually make minor modifications to the wiring (usually by adding/removing wire links) to allow the use of a standard filter module. The Solartron 7150Plus bench DMM is a good example of this. The stock filter module is a Schaffner part which is basically unobtainable on the UK market at a reasonable price (RS did sell them at one point, for ?50 plus VAT each). The cheapest fix (and IMO still a valid fix because it's reversible) is to get the wiremap for the Schaffner AC module, jumper the relevant voltage-select wires using Faston tabs and wire, and connect the now-loose L/N/E lines to the back of the new filter module. For safety, cover any exposed AC-level metalwork or wiring with heatshrink. You lose voltage selection, but gain a working DMM... To reverse the bodge -- cut off the heatshrink, unplug the tabs, and plug in a Schaffner voltage-switching filter module... Any port in a storm, right? -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/
