1 If you set the main setting (MAX) to 120% of the range, the main setting (MIN) to 0% of the range, the divider value n/m to 1,
and the deviation to –2%, up to 122.4% of the range can be generated.
2 The resolution in high resolution mode is 1 ppm of range. But, for the 30 A range, it is 100 µA.
3 Can be output when the source range is between 1% and 120% of the range.
4 Using measurement leads B8506ZK, 758917, or 758933, excluding measurement lead aging, and excluding the measurement
lead internal resistance.
5 Indicates the 1-hour stability under standard operating conditions with the ambient temperature in the range of 23°C ± 1°C
after 1 hour has elapsed with the voltage or current source output turned on.
6 Excludes the voltage drop due to the output resistance.
7 Specifications under standard operating conditions.
8 If the ambient temperature is between 5°C to 20°C or 26°C to 40°C, add the temperature coefficient compensation to the
accuracy.
9 For source ranges that exceeds 120% of each range, add 500 ppm of range.
10 For source ranges that exceeds 100 V, add 12ppm×(source voltage/1000)
11 Only for the 100 mA range, the specifications are defined for sinking current up to 30 mA. Immediately after sinking current
that exceeds 30 mA, errors exceeding the accuracy specifications may occur due to the increased temperature inside the
2560A.
