Maximum current calculation:
In the previous section, it was stated that the horizontal axis is the voltage and the vertical axis is the
current. The voltage-division value (V/div) is 1/4 of the test voltage. Ex. V/div value for 5V test voltage is
1.25V.
The maximum test current value is the test voltage divided by the limit resistance.
I
max
= V
test
/ R
limit
The current-division value is 1/4 of the maximum current value. For example, when the test voltage is 5V
and the limit resistance is
1KΩ, the maximum current value;
I
max
= 5V / 1K
Ω
= 5mA
The current-division value (I/div) is 5mA / 4 = 1.25mA /square.

Menu usage
In this section, the tracer menu usage of the UCE-DSO4200C device is explained. There are some buttons in
the tracer menu in Figure 5;
EXIT:
Used to return to the Main Menu. Also, during this process, the setting data is saved in the memory
(ct_settings.cfg).
DUAL:
It allows simultaneous use of Probe-1 (yellow color) and Probe-2 (red color) channels. If a single
channel is used, only the Probe-1 channel is enabled.
SCAN BTN:
Scans user buttons at regular intervals. When scanning is
active, the “
SCAN BTN
” button is
marked in green. The user button marked with green color is the step where the measurement is made at
that moment. When the step that does not want to be scanned is clicked, that step is cancelled. Inactive
stages are marked in red. Click again if it is desired to be reactivated. The buttons marked in gray are the
levels that will be scanned but are not active at that moment.
When the scan mode is active, the scan period is displayed at the top of the screen. Indicates the time
between two steps. The period time can be adjusted between 0.25 sec and 2 sec. Rotary-1's button is
pressed to increase the time, and Rotary-2's button to decrease it.
