How to Get Started

Warning
To prevent possible electrical shock, fire, or
personal injury:
•
Disconnect power and discharge all high-
voltage capacitors before you measure
resistance, continuity, capacitance, or a diode
junction.
•
Remove circuit power before you connect the
Product in the circuit when you measure
current. Connect the Product in series with
the circuit.
•
Do not use the HOLD function to measure
unknown potentials. When HOLD is turned
on, the display does not change when a
different potential is measured.

If familiar with the Fluke 80 Series DMM, read "Using the
Current Output Functions," review the tables and figures in
"Getting Acquainted with the Meter," and begin using the
meter.
If unfamiliar with Fluke 80 Series DMMs, or DMMs in
general, read "Measuring Electrical Parameters" in
addition to the sections referenced in the previous
paragraph.
The sections following "Using the Current Output
Functions" contain information about the power-up options,
and battery and fuse replacement instructions.
See Table 2 for an overview of the meter.
