I recently purchased 2 little voltmeters they look like the sort that would go in a control or instrument panel they are connected with just 2 wires which provide the operating supply ( they light up green and red) however the green one states it will work between 20and 500 volts and the red one between 60 and 480 volts. When they are both on the green one indicates normally around 241 volts the red one shows 235 volts why the discrepancy I know it's not much but makes you wonder if one of them is lying. Secondly I've noticed that the green one tracks voltage changes faster than the red one and that a few times the green one jumps down to 238 then up to 241 multiple times while the red one stays the same and I think can see a slight flicker in my filament lamps when this is happening incidentally both meters are connected to the same plug a 2 pin 5 amp one
Yesterday I went and did two jobs in Nottingham which along with lots of speed cameras has roadside LED displays that display your actual speed colour coded to tell you quickly if you are behaving correctly.
I bought a new sat nav recently and the GPS speedometer it displays matched the calibrated roadside displays, but the “analogue” speedometer on the dashboard with its swinging needle significantly over states the vehicle speed probably by about 10%.
As I was coming home on the motorways I did wonder how many people driving at around sixty and not keeping up with the flow of traffic actually think they are driving bang on the seventy speed limit.
Mind you it foes keep people well within the limit unlike the guy I worked with on Thursday who has just completed a speed awareness course, he lives in Wales and drives a transit van, not a good combination as I think there is only two roads in Wales on which you can drive at seventy in a Transit van.
We did have a discussion based on his recent updated knowledge from the deed awareness course about my Nissan NV200 van being described as a “car derived van” on its logbook, which should permit me to drive it faster than he can drive his Transit on many roads, a subject that Bod has commented on before.
