9. Press E. The calibrator clears your entry from the Control Display and copies

applied current.
Three softkey labels appear on the Control Display in the ac current function: “Currnt

MENU
• 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.
