3.2 Before Use

To perform a quick verification of the instrument’s normal operations, please follow the steps below：

(1) Connect to the Power Supply

The power supply voltage range is from 100 VAC to 240 VAC, the frequency range is 45 Hz to 440 Hz.

Connect the oscilloscope to the power supply line that came with the oscilloscope or any power supply

line that meets the local country standards. Turn on the power button, which on the back of the

oscilloscope. The soft power button in the front of the oscilloscope should be on red.

(2) Boot Check

Press the soft power button and the light should change to green.The oscilloscope will show a boot

animation, and then enter the normal interface.

(3) Connect Probe

Use probe in the attachment and connect it BNC terminal to the channel 1 BNC terminal of the

oscilloscope. Connect the probe’s main alligator clip to the “Compensating signal terminal” and the ground

clip is connected to the “Ground terminal” shown below. The output of the compensating signal should

be a 3 Vpp amplitude, default frequency is 1 kHz.

Figure 1 Compensating Signal and Ground Terminal

(4) Function Check

Press theAUTO key, a 3 Vpp 1 kHz square ware should appear. Repeat step 3 for all channels.

(5) Probe Compensation

When the probe is connected to any input channel for the first time, this step might be required in order

to match the probe and the input channel. Probes that are not compensated may lead to measurement

errors or mistake. Please follow the following steps:

Compensating signal terminal

Ground terminal

①Set the attenuation coefficient in the probe menu and the switch on the probe to 10x, and connect the

probe to CH1. Make sure the probe’s connector is properly connected with the oscilloscope. Connect the

probe’s main clip and ground clip to the oscilloscope’s compensating signal and ground terminal

respectively. Open CH1 and press theAUTO button.

②View displayed waveforms

Excessive Compensation Correct Compensation Insufficient Compensation

Figure 2 Compensating Calibration of Probe

③If the displayed waveform is look like the above “Insufficient Compensation” or “Excessive

Compensation”, use a non-metallic screwdriver to adjust the probe’s variable capacitance until the display

matches the "Correct compensation" waveform.

Warning: To avoid electric shock when measuring high voltage using the probe, please ensure

that the probe insulation is in good condition and avoid physical contact with any metallic part of

the probe.
