2 Performance Verification CC Load Effect Test category = performance This test measures the change in output current resulting from a change in output voltage from full scale to short circuit. 1 Turn off the power system and connect the current shunt, DMM, and electronic load (see Test Setup B). Connect the DMM directly across the current shunt. 2 Turn on the power system and program the instrument settings as described in the test record under “CC Load Effect”. 3 Set the electronic load for CV mode and program it to the output channel’s voltage as described in the test record under “CC Load Effect”. The output status should be “CC”. If it isn’t, adjust the load so that the output voltage drops slightly. 4 Divide the voltage drop (DMM reading) across the current monitoring resistor by its resistance to convert to amps and record this value (Iout). 5 Short the electronic load. For models N6751A and N6752A, wait 10 seconds for the output to stabilize. For models N6761A and N6762A, wait 60 seconds for the output to stabilize. Divide the voltage drop (DMM reading) across the current monitoring resistor by its resistance to convert to amps and record this value (Iout). The difference in the current readings in steps 4 and 5 is the load effect, which should not exceed the value listed in the test record for the appropriate model under “CC Load Effect”. 6 For models N6781A and N6782A only. Repeat steps 2 through 5 for the 1 A range and the 300 mA range. 7 For model N6784A only. Repeat steps 2 through 5 for the 1 A range, the 100 mA range, and the 10 mA range. CC Source Effect Test category = performance This test measures the change in output current that results from a change in AC line voltage from the minimum to maximum value within the line voltage specifications. 20 1 Turn off the power system and connect the ac power line through a variable voltage transformer or AC source. 2 Connect the current shunt, DMM, and electronic load (see Test Setup B). Connect the DMM directly across the current shunt. Set the transformer or AC source to nominal line voltage. 3 Turn on the power system and program the instrument settings as described in the test record under “CC Source Effect”. 4 Set the electronic load for the output channel’s voltage under “CC Source Effect”. The output status should be “CC”. If it isn’t, adjust the load so that the output voltage drops slightly. Series N6700 Service Guide
