There is a bug in the firmware of the AL539, AL539B when you select continuity and measure the resistance for example 6 ohms it reads this as 1.6 ohms. ....has anyone else spotted this fault?

Also why the small resistance measurement capability only up to 50 ohm?

...Also in oscilloscope mode why does it not hold the min max values on screen for very long? a touch hold function would be useful to keep the min max and waveform on screen when probes are removed from circuit.

a graphing mode would also be useful graphing min max values against time down to 500us/div

We got screwed on these units big time! They apparently dont work accurately for anything. See my other post about the CCA readings!

THEY NEED TO BUY THESE UNITS BACK FROM US!

looks to be a problem with firmware in the AL539B..... readings are out by a factor of 4 on continuity

e.g 4 ohms is read as 1 ohm and 8 ohms is 2.... etc.

Could please confirm there is indeed an error with resistance?

measure a solenoid on an injector or engine fuel valve for example

thanks

let me know if all is OK with your meter?

All I had to check yesterday was a tail light lamp, but the Autel showed zero resistance even though my Fluke 87V showed resistance.

Regardless of what I test in resistor mode, I get OL

Same here. I guess tech. support is either on vacation or terminated.

We need to get the word out about this company! at least the USA division will talk to you, but nothing they can do for the al539b, since it is not an American product!
