AC+DC ranges are specified from 2 % to 140 % of range.
1
20 A for 30 seconds on, 10 minutes off. >10 A not specified.

3 Add 20 counts in dual display ac over dc, dc over ac or ac+dc.
4 400 mA continuous; 550 mA for 2 minutes on, 1 minute off.
5 Verified by design and type tests.
6 Temperature coefficient: 0.1 X (specified accuracy)/C (<18 C or > 28 C).
Range: 1 nF to 10 mF
Accuracy: (1% +5) 1,2
Per manufacturer's manual, only 10 nF range is checked.
1
With a film capacitor or better, using relative mode (REL Δ) to zero residual.
