Hello everyone,
I'm a service engineer from Malaysia and come across a simple problem. I work with instrumentation and the problem I face with is regarding a Dissolve Oxygen Sensor. The sensor is used to measure oxygen in a sewage treatment plant by means of chemical reduction in its membrane...
My 2003 Toyota Echo has two back lights in the instrument cluster. One of the lights would flicker if I hit a bump or something. I swapped the lights, meaning I put the bad light in the good light's place and vice versa, to help determine if it was an issue with the bulb or something else. The...
First post, DIY.
I harvested this heavy transformer from an instrument that we took out of commission.
I live in a 220v country and I want to know if I can use this safely to run 120v tools (like routers etc).
1. It states 2kv. Is this ~2000 or ~4000 watts? (i.e. do I multiply by 120 or...
I was thinking a cheapo electric fence tester but need two probes for avian discouragement track. I have to test volts after installing. Oh and it's DC by the way.

Yes, I'm being lazy! Anyone have a Word/Excel version available, I've just lost loads of files from my laptop and this one does not appear to have been backed up.

Im looking to purchase my first test instrument and most probably a multifunction test instrument. Obviously a big money investment so i was wondering if anyone was aware of trialling or testing a test instrument before purchasing? My first instinct is probably not, but you dont know if you...

New tester should be light and portable, user configurable and able to conduct fixed appliance testing so I don't have to lug about a low resistance...
