Automatic Scope Measurements
The accuracy of all readings is within ± (% of reading + number of counts) from 18 °C to 28 °C. Add 0.1x (specific
accuracy) for each °C below 18 °C or above 28 °C. For voltage measurements with 10:1 probe, add probe accuracy. At
least 1.5 waveform period must be visible on the screen.
General
Inputs ...................................................................... A, B, C and D
DC Common Mode Rejection (CMRR) ................... >100 dB
AC Common Mode Rejection at
50, 60, or 400 Hz .................................................... >60 dB
DC Voltage (VDC)
Maximum Voltage
with 10:1 probe ................................................... 1000 V
direct (1:1) ........................................................... 300 V
Maximum Resolution
with 10:1 probe ................................................... 1 mV
direct (1:1) ........................................................... 100 μV
Full Scale Reading .................................................. 999 counts
Accuracy at 4 s to 10 μs/div, Fluke 190-xx2
2 mV/div .............................................................. ±(1.5 % + 10 counts)
5 mV/div to 100 V/div .......................................... ±(1.5 % + 6 counts)
Accuracy at 4 s to 10 μs/div, Fluke 190-xx4
2 mV/div .............................................................. ±(3 % + 10 counts)
5 mV/div to 100 V/div .......................................... ±(3 % + 6 counts)
Normal Mode AC Rejection
at 50 or 60 Hz ........................................................ >60 dB
AC Voltage (VAC)
Maximum Voltage
with 10:1 probe ................................................... 1000 V
direct (1:1) ........................................................... 300 V
Maximum Resolution
with 10:1 probe ................................................... 1 mV
direct (1:1) ........................................................... 100 μV
Full Scale Reading .................................................. 999 counts
Accuracy, Fluke 190-xx2
DC coupled:
DC to 60 Hz .................................................... ±(1.5 % +10 counts)
AC coupled, low frequencies:
50 Hz direct (1:1) ............................................ ±(1.5 % + 10 counts) −0.6 %
60 Hz direct (1:1) ............................................ ±(1.5 % + 10 counts) −0.4 %
With the 10:1 probe the low frequency roll-off point will be lowered to 2 Hz, which improves the AC accuracy for low
frequencies. When possible use DC coupling for maximum accuracy.
AC or DC coupled, high frequencies:
60 Hz to 20 kHz .............................................. ±(2.5 % + 15 counts)
20 kHz to 1 MHz ............................................. ±(5 % + 20 counts)
1 MHz to 25 MHz ............................................ ±(10 % + 20 counts)
For higher frequencies the instrument’s frequency roll-off starts affecting accuracy.
