Automatic Measurements
The accuracy of all measurements is within ± (% of measu number of
counts) from 18 °C to 28 °C. Add 0.1x (speci
fi c accuracy) for each °C below
18 °C or above 28 °C. At least 1.5 waveform periods must be visible on the screen.

Characteristic Description
Inputs 1, 2, 3 and 4
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 μ V
Full scale measurement 999 counts
Accuracy at 5 s to 10 μ s/div
2 mV/div ±(1.5 % + 10 counts)
5 mV/div to 100 V/div ±(1.5 % + 5 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 μ V
Full scale measurement 999 counts
Accuracy
DC coupled: DC to 60 Hz
±(1.5 % +10 counts)
AC coupled, low frequencies
50 Hz direct (1:1) ±(1.5 % + 10 counts)
60 Hz direct (1:1) ±(1.9 % + 10 counts)
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
