Automatic Scope Measurements

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	1100 counts
Accuracy
DC coupled:	±(1.5 % +10 counts)
DC to 60 Hz
AC coupled, low frequencies:	±(2.1 % + 10 counts)
50 Hz direct (1:1)
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.
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.
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	±(1.5 % + 10 counts)
DC to 60 Hz
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.
