1-10 Performance Verification

Table 1-5

5A range current readback accuracy limits

* As determined from digital multimeter and 1Ω resistor. See procedure.

Models2303and2303B5mArangereadbackaccuracy

The following test applies only to the Models 2303 and 2303B:

1. With the power off, connect the digital multimeter and characterized 3kΩ resistor to the

Model 2303 or 2303B OUTPUT SOURCE terminals, as shown in Figure 1-4. Be sure

to observe proper polarity and connections (3kΩ resistor between SOURCE + and DMM

INPUT HI; SOURCE - to DMM INPUT LO).
