Power Output Inspection
Output inspection is to ensure that the instrument can achieve its rated outputs
and properly respond to operation from the front panel.
1. Voltage Output Inspection
(1) When the instrument is under no load, select a channel and ensure the
output current setting for this channel is not at zero.

3.Primary User Guide
12
(2) Turn on the channel output, then ensure the channel is in Constant
Voltage output mode.
(3) Set some different voltage values on this channel; check if the actual
voltage value displayed is close to the set voltage value, and also that the
actual current value displayed is nearly to zero.
(4) Check CH1 and CH2 channel if the output voltage can be adjusted from
0.1V to the maximum rating.
2. Current Output Inspection
The following steps check basic current functions with a short across the
power supply's output:
(1) Power on.
(2) Connect a short across (+) and (-) output terminals with an insulated test
lead on this channel. Use a wire size sufficient to handle the maximum
current.
(3) Set the output voltage to the maximum rating on this channel.
(4) Turn on the channel output. Ensure the channel you used is in Constant
Current output mode.
(5) Set some different current values on this channel; check if the actual
current value displayed is close to the set current value, and to check if the
actual voltage value displayed is nearly zero.
(6) Check CH1 and CH2 channel if the output current can be adjusted from
zero to the maximum rating, When it is set to the maximum or minimum, a
beep is heard, indicating that the limit has been reached.
(7) Turn off the channel output and remove the short circuit from the output
terminals.
How to Implement the Probe Compensation
When connect the probe with any input channel for the first time, make this
adjustment to match the probe with the input channel. The probe which is not
compensated or presents a compensation deviation will result in the
measuring error or mistake. For adjusting the probe compensation, please
carry out the following steps:
1. Set the attenuation coefficient of the probe in the menu as 10X and that of
the switch in the probe as 10X (see "How to Set the Probe Attenuation
Coefficient" on P13), and connect the probe with the CH1 channel. If a
probe hook tip is used, ensure that it keeps in close touch with the probe.
Connect the probe tip with the signal connector of the probe compensator
and connect the reference wire clamp with the ground wire connector of

How to Set the Probe Attenuation Coefficient
The probe has several attenuation coefficients, which will influence the vertical
scale factor of the oscilloscope.
To change or check the probe attenuation coefficient in the menu of
oscilloscope:
(1) Push the function menu softkey of the used channels (CH1 channel or
CH2 channel).
(2) Select Probe Attenu (1X , 10X or other custom probe magnifications) in
the displayed channel setting window. The setting will remain in effect until
changed again after selection
This setting will be valid all the time before it is changed again.
Caution:
The default attenuation coefficient of the probe on the instrument is
preset to 10X.
Make sure that the set value of the attenuation switch in the probe
is the same as the menu selection of the probe attenuation
coefficient in the oscilloscope.

3.Primary User Guide
14
The set values of the probe switch are 1X and 10X (see Figure 3- 7).
Figure 3- 7 Attenuation Switch
Caution:
When the attenuation switch is set to 1X, the probe will limit the
bandwidth of the oscilloscope in 5MHz. To use the full bandwidth
of the oscilloscope, the switch must be set to 10X.
How to Use the Probe Safely
The safety guard ring around the probe body protects your finger against
any electric shock, shown as Figure 3- 8.
Figure 3- 8 Finger Guard
Warning:
To avoid electric shock, always keep your finger behind the safety
guard ring of the probe during the operation.
To protect you from suffering from the electric shock, do not touch any
metal part of the probe tip when it is connected to the power supply.
Before making any measurements, always connect the probe to the
instrument and connect the ground terminal to the earth.
How to conduct self-calibration
