2.7.8 Using the Ohms Function As A Current
Source
Table 2-4. Ohms Function Current Output Values
The Model 617 ohms function may also be used to generate
currents in decade values between InA and lOOpA. To use the
instrument in this manner, simply connect the Model 6011
cable to the INPUT jack and connect the red and black alli-
gator clips to the circuit under test. Select the resistance range
in accordance with the desired current (see Table 2-4). Note
that current flows from input high through input low. The
test voltage is less than 2V for all ranges 2GQ and less. except
when an overload occurs, in which case the compliance is
3OQv.
