. Uncertainty is valid for four-terminal connection with use of Option 70 or Option
140-41 Cable adapters. For two-wire connection from the terminals Hi-Lo na the front panel add to the specified uncertainty next +10
mOhm.

DC POWER uncertainty
Uncertainty of DC power can be calculated from the following formula:
d P = √ ( dU
2
+ dI
2
+ 0.01
2
) [%]
where dP is uncertainty of output power [%]
dU is uncertainty of set voltage [%]
dI is uncertainty of set current [%]
DC ENERGY uncertainty
Depends on voltage, current, time values. The best uncertainty is 0.016 %.
ACV uncertainty
