Operation flow
1
What is the measurement target
object?
What is the voltage of the target
object?
Check the maximum input voltage.
Check the maximum ground input voltage.
2
Connect the power cord to the
8855 unit.
Confirm that the power-supply voltage is 100 VAC to 200 VAC.
Confirm that the power-supply frequency is 50/60 Hz (sine
wave).
3
Connect to the measurement
target object.
Confirm that the power switch of the measurement target object
is turned off.
4
Turn on the power switch.
Turn on the power switch located
on the right side of the unit.
5
Select a measurement function.
In each screen, move the flashing cursor to the top (upper left)
item.
There are four selectable items: memory, recorder, R&M, and
FFT.
6
Set the time axis.
Press the DISP
or STATUS key.
Make settings in the display or status screen.
Sampling frequency (s) = Time axis (s/DIV) / 100 (number of
pieces of data per DIV)
7
Set the recording length.
Press the DISP
or STATUS key.
Make settings in the display or status screen.
Measurement time s (s) = Time axis (s/DIV) / recording length
(DIV)
8
Set the input channel.
Press the CHAN
key.
Make settings in the channel screen.
Voltage axis range, zero position, coupling, filter, etc.
9
Make trigger settings.
Press the TRIG
key.
Make settings in the trigger screen.
Trigger mode, pre-trigger, trigger type, trigger level, etc.
10
Begin measurement.
Press the START
key.
On the front panel of the main unit, press the green START
key located at the lower right corner.
The LED lights up, and measurement starts.
11
End measurement.
Press the STOP
key.
(Trigger mode: Continuous/Auto)
In the single-trigger mode, measurement ends when data of the
set recording length is obtained. In the continuous or auto
trigger mode, measurement ends when the STOP
key is
pressed. To abort meas urement, press the STOP
key twice.
12
Begin analysis.
Waveform zoom (Refer to Chapter 8 in the 8855 Quick Start Manual.)
A-B cursors (Refer to Chapter 8 in the 8855 Quick Start Manual.)
Numerical processing, waveform processing (Refer to Chapter 7 in the
8855 Instruction Manual.)
Waveform search (Refer to Chapter 8 in the 8855 Instruction Manual.)
