Operating Basics; Safe Test Lead Connections - Fluke 183 User Manual

Operating Basics

Before you take any of the measurements described in this section, follow
these steps:
For specified accuracy, allow the meter to stabilize for 30 seconds after
you turn on the meter.
Observe the safe test lead connections below when you remove the test
leads from the meter.
Always disconnect power to the circuit when you measure resistors,
capacitors, diodes, or continuity within the circuit.
Discharge capacitors before taking capacitance measurements.

Safe Test Lead Connections

To safely disconnect the test leads from the meter, first disconnect all test leads
from the circuit being tested, then disconnect the leads from the input
connectors.
To prevent electrical shock, do not insert unnecessary test
leads or metal pins into the A (amps) connector. Voltages
applied to any connector may be present at all other input
connectors. Only use the test leads supplied or
recommended (or their equivalent) with the meter. Refer to
the "Accessories" section.
