Table A-12. 2640A AC Voltage General Specifications (cont)
Specification Characteristic
Maximum Input Voltage The lesser voltage of:
300V ac rms from any terminal on channels 1 and
11 to earth.
150V ac rms from any terminal on channels 2
through 10, and 12 through 20 to earth.
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.
Maximum Volt-Hertz Product 2x10
6
Volt-Hertz product on any range, normal
mode input.
1x10
6
Volt-Hertz product on any range, common
mode input.
Temperature Coefficient 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%.
Accuracy at -20°C 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.
DC Component Error The presence of a dc voltage will cause an
indeterminate error in the reading of the ac voltage
on the input.
