Data Sheet

Cursor measurements (125, 124)
Sources: Input A, Input B
Modes: Single or dual vertical cursor, dual horizontal
cursor, risetime or falltime
Measurements:
Single vertical line: Average, min value, max value,
time from start of recording in roll mode
Dual vertical lines: ∆V at markers, time between
cursors, 1/T between cursors (in Hz)
Dual horizontal lines: High, low or ∆V – readout,
risetime and falltime: transition time, 0 %-level,
100 %-level, with markers at 10 % and 90 %
Accuracy: As oscilloscope
Bus health tester (Fluke 125 only)
Bus health automatically analyzes the electrical signals
on the network to give waveform data and measure
individual parameters. Automatic comparison of the
measurement results to the standards results in “good”
or “false” indicators to be displayed per parameter.
Bus types and reference standards used:
AS-i (EN50295, 166 kb/s)
®
;
CAN-bus (ISO-11898, up to 1 Mb/s);
Interbus S (EIA-485, up to 10 Mb/s)

or user defined system
Measured parameters: Baud rate, risetime, falltime,
high level, low level, distortion, amplitude and jitter,
with comparison to system’s standard values
Power measurements (Fluke 125 only)
Measure types: Watt, VA, VAR, Power Factor (PF)
Power configuration: Single phase or balanced
3-phase (delta-configuration) mains supply
Voltage measurement: Channel A, using STL120,
voltage probe or direct input
Current measurement: Channel B, using i400s
current clamp (included) or other compatible clamp
Current clamp or shunt sensitivity:
0.1/1/10/100/1000 mV/A, 10 mV/mA and 400 mV/A
Harmonics mode (Fluke 125 only)
Converts waveform information into a harmonics dis-
play (using FFT processing), which shows the relative
amplitudes of the 1st up to the 33rd harmonic
Harmonics frequency range: DC to 33rd harmonic
(fundamental ≤ 60 Hz); DC to 24th (fundamental
≤ 400 Hz)
Analyzed waveform: Voltage waveform (Ch.A),
current waveform (Ch.B) or power (Ch.A x Ch.B),
automatically generated
Display: Bargraph showing 1st up to 33rd harmonic,
amplitude displayed in % relative to fundamental
Timebase setting: 5 ms/div.
Measurements: Relative amplitude of individual
harmonic; THD in %r or %f
