Dave - the soft case seems to have disappeared from the store - are we going to see that return (particularly one suited to the larger BM786)?

Are the calibration procedures documented for this meter?

No they aren't.
They usually only release this to trusted major dealers.

I don't particually want to carry multiple cases, so I might look into if it's possible to get one that suits all meters.

If you are wondering why your new BM786 multimeter didn't come with batteries, it's because DHL Express took it upon themselves to open every package and remove them & send them back. Alkaline batteries. Freak'n ALKALINE BATTERIES.

Did they say why they removed alkaline batteries??? Or did the guy at the Xray machine just figure they should have them removed after spotting batteries...

DHL's policy appears to prohibit the international shipping of Alkaline batteries, in all cases. The document is US-based, but presumably the International provisions apply network-wide. See page 7.

For international shipping it makes sense to not include standard batteries. They only add to the weight and there is a small risk of the batteries to cause trouble: An unintentional short in a smashed parcel may start a fire - not very likely but alkaline cells often have quite some power. The other problem is leakage  :horse: - reduced air pressure in an aircraft can accelerate this.

Another point about not having batteries is that it makes it easier to spot a possible bomb from xray pictures.

There is no real need to have standard AA batteries shipped with the DMM. These are better bought locally in most places.

So Dave - what are you going to do with a few kilos of alkaline batteries?

Looks like I'll have to rmeove the batteries for all international DHL shipments. Local will still have them.

Woo Hoo -- just arrived! (3 days to travel to the other side of the globe) It's a thing of beauty. Calibration out of the box is pretty damn good. Here is a recently calibrated 34401 (by Keysight at the end of November 2020) (warmed up for an hour along with the source. showing 5.00000V from a DMMCheck+. The EEVBlog Brymen is 1 count high. (it's been on for 30 minutes. It was 5 counts high for the first minute, then quickly settled at 5.0001V, and it hasn't budged since then.

on DC milli-amps (@1.0mA), it is 2 counts higher than my 34401 . Resistance, 600ohm range (100ohms) it's 3 counts higher, and the 6k, 60k and 600k ranges (using 1K, 10K, and 100K resistors), the EEVBlog meter is within 1 count of the calibrated 34401.

For AC volts (5V AC, square wave @ 100hz), it is 24 counts lower than my 34401.

Pretty much spot on -- I don't think it could be any closer.

I'm very happy with my purchase.

The batteries were in the package (3 energizer aaa in a small ziplock bag) but not installed in the meter -- so I guess DHL didn't remove all of them...

One very minor error in the manual -- on page 16, where it depicts a north-american style outlet -- it has the neutral and live sides reversed. If the ground min is on the botom, the live side is on the right (and is slightly shorter than the neutral that is to the left). In that diagram on that page, the manual shows the live side is on the left.
