300V ac rms from any terminal on channels 1 and 11 to any other terminal.

150V ac rms from any terminal on channels 2 through 10 and 12 through 20 to any other input terminal.

2x106 Volt-Hertz product on any range, normal mode input.

1x106 Volt-Hertz product on any range, common mode input.

Linear interpolation between 2 applicable points for temperatures between 28ºC and 60ºC, or -10ºC and 18ºC, e.g., if the applicable specification at

28ºC is 2% and the specification at 60ºC is 3%, then the specification at 40ºC is

(3%-2%)x(40-28)/(60-28)+2%=2.375%.

Multiply the -10°C to + 60°C accuracy specification by 2. After 1 hour warm-up. For accuracy between -10°C and -20°C, interpolate linearly.

The presence of a dc voltage will cause an indeterminate error in the reading of the ac voltage on the input.
