Fluke 125 Users Manual Making Measurements The reading area displays the numeric readings of the chosen measurements on the waveform that is applied to the input jack. Connecting the Inputs Voltage measurements See figure 2-3. For proper grounding connect the short ground leads d to the same ground potential. You can also use test lead c for grounding. See also Using Proper Grounding in chapter 9. Ohm (Ω), continuity, diode, and capacitance measurements See figure 2-4. Use the red shielded test lead from input A and the black unshielded ground lead from COM (common). Current measurements See figure 2-5. Select the probe setting that matches the used current clamp and its setting (e.g. 1 mV/A), see Chapter 1, Measurement Probes and Settings. Temperature measurements See figure 2-6. Use a 1 mV/°C or 1 mV/°F temperature transmitter to get the correct temperature reading. Power measurements See figure 2-7.

Making Measurements
The reading area displays the numeric readings of the
chosen measurements on the waveform that is applied to
the input jack.
Connecting the Inputs
Voltage measurements
See figure 2-3. For proper grounding connect the short
ground leads
to the same ground potential.
You can
also use test lead
for grounding. See also Using
Proper Grounding in chapter 9.
Ohm (
Ω
), continuity, diode, and capacitance
measurements
See figure 2-4.
Use the red shielded test lead from input A
and the black unshielded ground lead from COM
(common).
Current measurements
See figure 2-5. Select the probe setting that matches the
used current clamp and its setting (e.g. 1 mV/A), see
Chapter 1, Measurement Probes and Settings.
Temperature measurements
See figure 2-6. Use a 1 mV/
°
C or 1 mV/
°
F temperature
transmitter to get the correct temperature reading.
Power measurements
See figure 2-7. Select correct probe settings for voltage
measurement on input A, and current measurement on
input B.
