Read First – Safety Information
In this calibration manual, a Warning identifies conditions and actions that pose
hazard(s) to the user. A Caution identifies conditions and actions that may damage the
Calibrator or the test instruments.
To avoid possible electric shock or personal injury:
•
DO NOT use the Calibrator if it looks damaged.
•
Follow all safety procedures for the test and calibration equipment you
use.
•
Examine the Calibrator before use. Look for cracks in the case, missing plastic,
or damaged insulation around the connectors.
•
Inspect the test leads for damaged insulation or exposed metal. Check for
test lead continuity. Replace damaged test leads as necessary.
•
Do not use the Calibrator if it operates abnormally. Protection may be
impaired. When in doubt, have the instrument serviced.
•
Do not apply more than the rated voltage, as marked on the Calibrator,
between terminals or between any terminal and earth ground.
•
Never touch the probes to a voltage source when the test leads are plugged
into the current terminals.
•
Select the proper function and range for each measurement.
•
Disconnect the test leads before changing to another measure or source
function.
•
When using probes, keep fingers behind the finger guards on the probes.
•
Use caution when working above 30 V ac rms, 42 V ac peak, or 60 V dc.
Such voltages pose a shock hazard.
•
Connect the common lead (COM) before connecting the live test lead. When
disconnecting test leads, disconnect the live test lead first.
•
Always place the 5520A calibrator in Standby (STBY) mode between tests
and before handling the test connections or cables.
•
Remove test leads from the Calibrator before opening the battery door.
•
Do not operate the Calibrator around explosive gas, vapor, or dust.
•
During normal operation, only use four properly installed AA batteries to
power the Calibrator.
•
Make sure the battery door is closed and latched before you operate the
Calibrator.
•
During calibration, use only specified calibration equipment listed in
Table 6.
