Inputs

Voltage Measurements

For proper grounding, connect the short ground leads to
the same ground potential, see Figure 8 setup 4. You can
also use test leads for grounding, see Figure 8 setup 5.
See also Grounding Guidelines on page 68.
Ohm, Continuity, Diode, Capacitance
Measurements
Use the red shielded test lead from input A and the black
unshielded ground lead from COM (common) for Ohms
(Ω), continuity, diode, and capacitance measurements.
See Figure 7 setup 1.

Current Measurements

Select the probe setting that matches the used current
clamp and its setting, for example, 1 mV/A. See Figure 9
and Measurement Probe Setup.

Temperature Measurements

Use a 1 mV/°C or 1 mV/°F temperature transmitter (not
available in all countries) to get the correct temperature
reading. See Figure 9.

Power Measurements

Select correct probe settings for voltage measurement on
input A and current measurement on input B. See
Figure 7 setup 2.
IntellaSet™ / AutoReading
The AutoReading function uses Fluke IntellaSet™
technology to enable hands-off operation to display meter
readings that correspond with the shape of the waveform.
This function automatically selects the meter readings
that are most often used with the measurement of the
waveform shape. As an example, when the waveform is a
line voltage signal, the V ac + dc and Hz readings show
automatically.
To enable the AutoReading function on input A:
1. Push  to open the Scope and Meter button bar.
2. Push 1 to open the MEASURE menu. See
Figure 10.
3. Push 1 to select the AutoReading to ON.
4. Push 4 to select Done and close the menu.
To disable this function, repeat the steps and select the
AutoReading to OFF.
