For sink operation (quadrants II and IV) without sink mode enabled, add 10 % of compliance range and ±0.02 % of limit settling to the
corresponding voltage source accuracy specifications. For 100 mV range add an additional 60 mV of uncertainty. Specifications apply with
sink mode enabled.
11
For sink operation (quadrants II and IV) without sink mode enabled, add 0.06 % of limit range to the corresponding current limit accuracy
specifications. Specifications apply with sink mode enabled.

Add 150 µs when measuring on the 1 A range.

40 V range

Maximum output voltage = 42 V – (total voltage drop across source leads).
Maximum 1 Ω source lead.
6 V range

Maximum output voltage = 8 V – (total voltage drop across source leads).
Maximum 1 Ω source lead.
Internally sensed temperature overload puts the instrument in standby mode
