Operation Rules; Warm-Up Time - Fluke Calibration 5322A Operator's Manual

The measurement takes approximately 10 seconds and is used in the Loop/Line
impedance function. The measurement can cause current spikes to occur on the
mains supply, so this start-up measurement can be disabled if desired. Access to
changing the setting is in Setup>Line&Loop scan, and the Start Up SCAN
parameter. When the parameter is set to Off, initial residual resistance
measurement during power up is omitted.
The Product resets to its reference state whenever mains power is
removed and then reapplied to the Product.

Operation Rules

The following rules should be strictly observed to ensure
correct operation of the Product:
•
Turn on and turn off the Product only with the power switch on
the rear panel.
•
Do not connect the Product 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 Product
through the vent openings.
•
The Product must not be operated in a dusty environment. It
was designed to be used in a laboratory.
•
Do not operate the Product outside its operating temperature
range.
•
Connect the instruments to be calibrated to the proper output
terminals.
• If the instruments to be calibrated are not connected to the
Product output terminals using their original cables, ensure
that only cables rated for the applicable voltage and current
are used.
Whenever possible, use the setup menu to ground the LO output terminal. See
GND on the setup function, applicable for the low-resistance source, high-
resistance source, and voltage calibrator (VLC option).

Warm-Up Time

Once the Product reaches its reference state, it can be used for calibration.
However, the Product will only make calibrations to its specified accuracy after it
has been allowed to warm up for at least 30 minutes.
During these first 30 minutes, the Product cannot calibrate. If
Product calibration is attempted during this period, the Product
indicates that it cannot access the calibration.
