3-16 Measurements and Sourcing Voltage Model 6487 Reference Manual
5. Enter the desired voltage source value, then press ENTER. Voltage values are
changed immediately from this configuration by pressing the arrow keys. The and
arrows are used to select the digit being edited and the V-SOURCE and keys
change the value. The digits will not increment beyond the limit for the present
source range with subsequent source arrow key presses.
klqb The V-SOURCE
and keys will operate in the same manner as the RANGE
and
keys if they are not being used to change the voltage source values.
6. After the voltage value and range is selected, press ENTER to advance to the cur-
rent limit display and select the desired current limit. The current limit display
offers different choices depending on the source range (Table 3-7). Pressing
ENTER or EXIT from this display returns you to the normal readings display.
Sourcing voltage
t^okfkd Always turn off the Model 6487 power before changing voltage source
connections to avoid a possible shock hazard.
Perform the following steps to source voltage:
Step 1. Set up voltage source
Press either of the V-SOURCE adjustment keys, then use a manual RANGE key to set the
voltage source range. Set the voltage and current limit to the desired values using the cur-
sor and RANGE keys.
