Fluke 725Ex User Manual page 15

To avoid electric shock, injury, damage to the Calibrator, or ignition of an explosive atmosphere,
follow all equipment safety procedures.
•
Use the Calibrator only as described in this User Manual and the Fluke
Drawing) or the protection provided by the Calibrator may be impaired.
•
Inspect the Calibrator before use. Do not use it if it appears damaged.
•
Check the test leads for continuity, damaged insulation, or exposed metal. Replace damaged test leads.
•
When using probes, keep fingers behind the finger guards on the probes.
•
Never apply more than 30.0 V between the input terminals, or between any terminal and earth ground.
•
Applying more than 30.0 V to the input terminals invalidates the Calibrator's Ex Approval and may
result in permanent damage to the unit so it can no longer be used.
•
Use the proper terminals, mode, and range for the measuring or sourcing application.
•
To prevent damage to the unit under test, be sure the Calibrator is in the correct mode before
connecting the test leads.
•
When making connections, connect the COM test probe before the live test probe. When
disconnecting, disconnect the live probe before the COM probe.
•
Never open the Calibrator case. Opening the case invalidates the Calibrator's Ex Approval.
•
Make sure the battery door is closed and latched before entering an Ex hazardous area or using the
Calibrator. See "Ex Hazardous Areas".
•
Replace the battery as soon as the B (low battery) symbol appears to avoid false readings that can
lead to electric shock. Remove the Calibrator from the Ex-hazardous area before opening the battery
door. See "Ex Hazardous Areas".
•
Remove test leads from the Calibrator before opening the battery door.
•
Measurement Category I (CAT I) is defined for measurements performed on circuits not directly
connected to the mains.
•
Turn off circuit power before connecting the Calibrator mA and COM terminals in the circuit. Place
Calibrator in series with the circuit.
