I found a typo in the "How good is your multimeter?" article, but I cannot edit it (it's an image).

In the "Measuring 3.3 V d.c." section, in the "Gossen Metrawatt M249A" column, in the "Error digits" row it says:

0.00015

, but instead should be:

0.0015

if 15 error digits in a 5.9999 V d.c. range are wanted.

Thus, the subsequent calculations are also wrong, and should be changed from:

• value at upper %  3.30066
• Error digits            0.00015
• final reading          3.30081
• Error %                 0.025%

to:

• value at upper %  3.30066
• Error digits            0.0015
• final reading          3.3022
• Error %                 0.067%
