5700A/5720A Series II
Operators Manual
4-28
• The “Currnt Output” softkey selects one of three locations for current output: the
OUTPUT binding post (NORMAL, which is the OUTPUT HI binding post, also the
default setting); AUX, which is the AUX CURRENT OUTPUT binding post, or
5725A, which is the 5725A Amplifier binding posts. (The 5725A must be turned on,
but not necessarily activated.)
Note
If AUX is selected for a calibrator configured for rear output, error
message: “Compliance voltage exceeded” will be displayed. For rear
output, use the NORMAL setting.
• The “Range” softkey selects autorange or lock for the present range. When the range
is set to AUTO (the default setting), the calibrator automatically selects the lowest
possible range.
• The “Setup Menus” softkey opens the setup menu.
4-28. AC Current Output
To set an ac current output, proceed as follows:
1. Make sure the calibrator is in standby (STANDBY annunciator lit). Press O if
necessary.
2. If the UUT is not connected, connect it now as described earlier in this chapter under
“Connecting the Calibrator to a UUT.”
3. Set the UUT to measure ac current on the appropriate range.
4. Press up to seven numeric keys to select an amperage level.
5. Press U or m if necessary.
6. Press A.
7. The Control Display now shows the amplitude of your entry. If you made an entry
error, press C to clear the display, then reenter the value. The following illustration
of the Control Display assumes an entry of 125 mA:
