This is my multi-meter. It’s a bit of kit that goes everywhere with me. I work on the signalling side of the operation, checking signals across East Anglia. Sometimes there can be a fault and on one occasion I had to spend up to 12 hours fixing it. But that’s the nature of the job. A lot can happen and from one day to the next, it can be very different. I know that if I keep the signals in good working order (and part of that involves giving the electrical circuit a good clean), then I’m helping to keep the network running smoothly. That’s why the multi-meter is so important. And I use it
every day.
