Title: T4D 52
Post by: retiredcaps on March 01, 2013, 06:50:27 PM

Hi Martin,

I'm not 100% sure regarding the "drama", but as soon as I saw your shirt, I knew you would handle it in a gentlemanly manner.

I wasn't surprised that you would try the self calibration because I have been following your channel for a while and knew of your modifications to the Fluke 287.

Anyway, I'm looking forward to the Agilent multimeter review.

PS. The Amprobe AM-160 on the 1.5000V DC test is borderline at 1.5007.

PPS. When you calibrated the UT61E, I'm curious why you used the 5.0000 and not the 1.5000?  Since the UT61E can display 22,000 counts, wouldn't it be better to calibrate with an extra digit even though it is LSD?

Hi Martin,

For the U1232A vs 115 video, can you please test the autoranging speed of both by

a) hooking both up to a 5.00V DC source, powering off the source, wait 3 seconds and then turn on the 5V source?

b) do the same above but have a 20V source (so they both "range up")

There have been reports that the U1232A autoranging is slow?

PS. While testing scenario b) above, give both a flick to the ACV setting and see if both settle down to 0.0V AC?

;-) Thanks good man!

Good point...the more places after the decimal the better...might be a tad fiddly but great idea.
Will see if I can do it at the same time as the Amprobe.

Noted....just hope my brain remembers...a fair bit going on but good points.
