2) It can quickly view several continuous signals without adjusting the oscilloscope. This function is very
useful if you need to use two probes at the same time, or if you can only use the probe with one hand
because the other hand is full.
3) Control the automatic adjustment setting of the oscilloscope.
2.11 Load Factory Settings
Open the main menu, tap “User Settings” to enter the user setting page. Tap “Factory Settings” and the dialog
box for loading factory settings will pop-up. Press “OK” and load the factory settings. The dialog box for loading
factory settings is shown in Figure 2-12.

2.12 Use Auto-calibration
Open the main menu, tap “User Settings” to enter the user setting page. Tap “Auto Calibration” to enter the auto-
calibration mode. When the auto-calibration function is active, the upper left corner of the screen displays
“Calibrating” in red, and after calibrating is finished, the word in red disappears. When the temperature changes
largely, the auto-calibration function can make the oscilloscope maintain the highest accuracy of measurement.
⚫ Auto-calibration should be done without probe.
⚫ Auto-calibration process takes about two minutes.
⚫ If the temperature changes above 10℃, we recommended users perform the auto-calibration.
2.13 Passive Probe Compensation
Before connecting to any channels, users should make a probe compensation to ensure the probe match the input
channel. The probe without compensation will lead to larger measurement errors or mistakes. Probe
compensation can optimize the signal path and make measurement more accurate. If the temperature changes 10℃
or above, this program must run to ensure the measurement accuracy.
Probe compensation may be conducted in the following steps:
1) First, connect the oscilloscope probe to CH1. If a hook head is used, make sure that it is in good
connection with the probe.
2) Connect the probe to the calibration output signal terminal and connect the probe ground to the ground
terminal. As shown in Figure 2-13.
