Reset the Calibrator
At any time during front-panel operation, return the Calibrator to the power-up state with
. When is pushed, it:
• Returns the Calibrator to the power-up state: 0 mV dc, standby, internal guard, and
internal sense.
• Clears the stored values for limits, offset, scale, and error mode reference.
• Secures the Calibrator if the passcode had been entered.
Operate and Standby Modes
When the OPERATE light above the output terminals is illuminated, the output value and
function shown on the display are active at the selected terminals. “Operate” also shows
on the display.
When the STANDBY light above the output terminals is lit, all 5730A Calibrator binding
posts except GROUND are open-circuited. “Standby” also appears on the display in this
case.
Visual Connection Management output terminals illuminate in green to indicate which
terminals are active and provide guidance to ensure the proper connection of cables for
each function.
Push to put the Calibrator into the OPERATE state. Push to put the
Calibrator in the STANDBY state.
If any of the subsequent events occur during operation, the Calibrator automatically
switches to standby mode:
• The key is pushed.
• A voltage ≥22 V is selected when the previous output voltage was <22 V.
• The output location is changed, for example by selecting an amplifier. The
exception is when the 5725A is selected for ac voltage or current, provided the
Calibrator current output location is set to “5725A.”
• The output function is changed from one function to another.
