1.3 Probe
1.3.1 Probe Safety
A guard around the probe body provides a finger barrier for protection from
electric shock.
Picture 1.3-1
Connect the probe to the oscilloscope and connect the ground terminal to ground
before you take any measurements.
1.3.2 Probe Attenuation Setting
Probes are available with various attenuation factors which affect the vertical
scale of the signal. The Probe Check function verifies that the Probe attenuation
option matches the attenuation of the probe.
You can push a vertical menu button (such as the CH 1 MENU button), and select
the Probe option that matches the attenuation factor of your probe.
Be sure that the attenuation switch on the probe matches the Probe option in the
oscilloscope. Switch settings are 1X and 10X.
Note： ● To avoid electric shock when using the probe, keep fingers behind the
guard on the probe body.
● To avoid electric shock while using the probe, do not touch metallic
portions of the probe head while it is connected to a voltage source.
Connect the probe to the oscilloscope and connect the ground terminal
to ground before you take any measurements.
Note
:
The default setting for the Probe option is 1X.
Note:
When the attenuation switch is set to 1X, the probe
limits the bandwidth of the
oscilloscope to 6MHz (according to Probe spec). To use the full bandwidth of the

1.3.3 Probe Compensation
As an alternative method to Probe Check, you can manually perform this
adjustment to match your probe to the input channel.

1. Set the Probe option attenuation in the channel menu to 10X. Set the switch to
10X on the probe and connect the probe to channel 1 on the oscilloscope. If you
use the probe hook-tip, ensure a proper connection by firmly inserting the tip
onto the probe.
2. Attach the probe tip to the PROBE COMP～3V connector and the reference
lead to the PROBE COMP Ground connector. Display the channel and then
push the “AUTO” button.

Setting CH1, CH2 Channels
Each channel has its own separate Menu. The items are set up separately
according to each channel.
1. Choosing Coupling
Take the CH1 for example; the tested signal is a sine wave signal with DC
deflection:
● Press“CH1”→“Coupling”→“AC”, Set to AC couple mode. It blocks the DC
component of the input signal.
● Press“CH1”→“Coupling”→“DC”, Set to DC couple mode. Both DC and
AC component could be obstructed.
● Press“CH1”→“Coupling”→“GND”, Set to GROUND mode. It disconnects the
input signal.

2. Bandwidth Limiting
Take the CH1 for example; the tested signal is a pulse signal with the high
frequency surge:
● Press “CH1”→“BW Limit”→ “On”，Set the band width Limited to open state. The
high frequency component which is higher than 20MHz obstructed.
● Press“CH1”→“BW Limit”→ “Off”, Set bandwidth Limited to close state, the High

makes the vertical scaling in a 1-2-5-step sequence from 2mv/div, 5mv/div,
10mv/div to 10v/div.
● Press “CH1”→“Volts/Div”→“Fine”. This setting changes the vertical to small
steps between the coarse settings. It will be helpful when you need to adjust the
