Preparing the Calibrator for Operation
Operation Rules 2
2-7
Note
The Calibrator resets to its reference state whenever line power is removed
and then reapplied to the Calibrator.
Operation Rules
The following rules should be strictly observed to guarantee correct operation of the
calibrator:
• The calibrator can only be switched on and off by pressing the power switch located at
the rear panel.
• Do not connect the Calibrator to a power source with a voltage other than that set by
the voltage selector on the rear panel.
• Do not block the vent openings located at the rear and bottom panels.
• Keep all liquids and small objects from entering the Calibrator through the vent
openings.
• The Calibrator must not be operated in a dusty environment. It was designed to be used
in a laboratory.
• Do not operate the Calibrator outside its operating temperature range.
• Connect the instruments to be calibrated to the proper output terminals. There is no
way to protect the Calibrator from damage caused by improper connections.
• Do not plug in banana connectors that are thicker than that for which the terminals
were designed.
• Whenever possible, use the setup menu to ground the LO output terminal (GND on the
setup function).
• If the instruments to be calibrated are not connected to the Calibrator’s output terminals
using their original cables, ensure that only cables suitable for the calibration voltage
and current are used.
Warm-Up Time
Once the Calibrator reaches its reference state, it can be used for calibration. However,
the Calibrator will only make calibrations to its specified accuracy after it has been
allowed to warm-up for at least 30 minutes.
Note
During these first 30 minutes, the Calibrator itself cannot be calibrated. If
calibration is attempted during this period, the Calibrator will display
“cannot access the calibration”.
