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.
Accuracy, FLUKE 190-xx4
DC coupled:
DC to 60 Hz ................................... ±(3 % +10 counts)
AC coupled, low frequencies:
50 Hz direct (1:1) ............... ±(3 % + 10 counts) - 0.6%
60 Hz direct (1:1) .............. ±(3 % + 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 ............................ ±(4 % + 15 counts)
20 kHz to 1 MHz ........................... ±(6 % + 20 counts)
1 MHz to 25 MHz ....................... ±(10 % + 20 counts)
For higher frequencies the instrument’s frequency roll
off starts affecting accuracy.
Normal Mode DC Rejection .................................. >50 dB
All accuracies are valid if:
• The waveform amplitude is larger than one division
• At least 1.5 waveform period is on the screen
AC+DC Voltage (True RMS)
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 ........................................ 1100 counts
Accuracy, FLUKE 190-xx2
DC to 60 Hz .................................. ±(1.5 % + 10 counts)
