Hi , new Member here but I have been reading the Forums for a while and Ordered a Uni-T 61E, for playing around with small projects at home and measure the odd line voltage thing at work, but at least to me it was doing strange things like when auto ranging while measuring AC voltage of an outlet and getting stuck in Manual mode, so I returned it and replaced it with the UT-139C having read about it here too and knowing it was safer for AC measurements anyway since it has 600v Fuses not 250v like the UT-61E . However I am sure the 61E was able to do the Red LED test as can my Old POS DMM I have had for 15-20yrs, but my new 139C doesn't seem to be able too ...or I am doing something wrong ?
Is there a good Tutorial on Testing a DMM , incase this one needs to go back too while it can, it seems okay autoranging on AC unlike the 61E ...thanks.
Also I always seem to have an issue measuring AC at an Outlet easily , so my thought was to splice a polarised Lamp cord ( so you can't get it wrong) into a set of cheap DMM leads I still have hanging around in the Shop , and use that instead of the probes?.
Thanks for your help/comments
