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, see section '10:1 Probe' on page 129. 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.
