Measurement category

This instrument can be used for measurement under class I.

Warning :
This instrument is only allowed to be used in the specified measurement class. Measurement class definition

• Class I refers to measurements taken on a circuit not directly connected to the main power supply. For example, measurements made on circuits that are not exported from a main power supply, especially from a protected (internal) main power supply. In the latter case, the instantaneous stress will change. Therefore, the user should understand the instantaneous capacity of the instrument.
• Class II refers to measurements taken on a circuit directly connected to low-voltage instruments. For example, measurements made on household appliances, portable tools, and similar equipment.
• Class III refers to measurements taken on construction equipment. For example, measurements made on switchboards, circuit breakers, circuits (including cables, busbars, junction boxes, switches, sockets) in fixed equipment, as well as equipment for industrial use and certain other equipment (for example, fixed motors permanently connected to fixed instruments).
• Class IV refers to measurements taken at the source of low-voltage equipment. For example, measurements made on electricity meters, primary overcurrent protection equipment, and pulse control units.

Ventilation Requirement

This oscilloscope uses a fan to force cooling. Please make sure that the air intake and exhaust areas are free from obstructions and have free air. When using the oscilloscope in a bench-top or rack setting, provide at least 10 cm clearance beside, above and behind the instrument for adequate ventilation.
Note :
Inadequate ventilation may cause an increase of temperature in the instrument, which would cause damage to the instrument. So please keep the instrument well ventilated and inspect the air outlet and the fan regularly.

Working Environment

Installation (Overvoltage) Category

This product is powered by mains conforming to installation (overvoltage) category II. Warning:

• Ensure that no overvoltage (e.g. from lightning) reaches the product. Otherwise, the operator may be in danger of receiving electric shock.
• Installation (Overvoltage) Category Definitions
• Installation (overvoltage) category I refers to signal level which is applicable to equipment measurement terminals connected to the source circuit. Among these terminals, precautions are done to limit the transient voltage to a low level.
• Installation (overvoltage) category II refers to the local power distribution level
• which is applicable to equipment connected to the AC line (AC power).
• Pollution Degree
• Pollution Degree 2
• Pollution Degree Definition
• Pollution Degree 1: No pollution or only dry, nonconductive pollution occurs. The pollution has no effect. For example, a clean room or air-conditioned office environment.
• Pollution Degree 2: Normally only nonconductive pollution occurs. Temporary conductivity caused by condensation is to be expected. For example, indoor environment.
• Pollution Degree 3: Conductive pollution or dry nonconductive pollution that becomes conductive due to condensation occurs. To be found in industrial environment or construction sites (harsh environments). For example, sheltered outdoor environment.
• Pollution Degree 4: The pollution generates persistent conductivity caused by conductive dust, rain, or snow. For example, outdoor areas. Security level Class 1 – Grounded products

Preparation before use

1. To Adjust the Supporting Legs
   There is a bracket design at the bottom of the machine, and the bracket should be adjusted appropriately to tilt the oscilloscope slightly upwards, which can better stabilize the placement of the oscilloscope and facilitate observation and operation. When not using the machine, simply close the bracket.

2. To Connect to AC Power
   The specifications of the AC power supply that this oscilloscope can input are:
   100- 120V, 50/60/400Hz; 100-240V, 50/60Hz. Please connect the oscilloscope to the power supply using the power cord provided in the attachment, as shown in the figure.
   To avoid electric shock, ensure that the instrument is correctly grounded.

3. Turn-on Checkout
   When the machine is properly plugged in and the oscilloscope is powered on, press the power button in the lower left corner of the front panel to start the oscilloscope. During the startup process, all the button lights on the front panel will light up for a few seconds, and the oscilloscope will perform a series of self checks. After the self check is completed, the startup screen will appear.

4. Function Inspection

• Click on [Default Setup] in the button area to restore the oscilloscope to its factory settings.

• Connect the grounding crocodile clamp wire of the probe to the grounding terminal in the figure below.

• Connect the probe to the input terminal of channel 1 and the compensation signal output terminal marked in the figure below.

• Set the probe attenuation ratio to X10 and click on the button area [Auto Scale].

•  Observe the pictures on the waveform to see if the square wave signal is displayed normally. As shown in the following figure.

• Check CH2~CH4 channels using the same method. If the square wave waveform displayed in the time base does not match the figure above, you can follow the instructions in the section on Probe Compensation

Warning :

To avoid electric shock when using the probe, please make sure that the insulated wire of the probe is in good condition. Do not touch the metallic part of the probe when the probe is connected to high voltage source.

Tip:
The probe compensation signal can only be used for probe compensation adjustment and cannot be used for calibration.

Probe Compensation

When connecting the probe to any input channel for the first time, this adjustment is required to match the probe with the input channel. Uncompensated or offset probes can lead to measurement errors or errors.

• Perform the first four steps of the previous section on “Function Check”.
• Compare the waveform with the figure below.

If necessary, use a non-metallic screwdriver to adjust the variable capacitance on the probe until the waveform displayed on the screen is “Perfectly compensated” as shown in the figure above. If necessary, repeat this step. The adjustment method is shown in the following figure.

Touch Screen Controls

This series of oscilloscopes provides a 10.1 inch super capacitive touch screen, which supports multi-touch and gesture operation with high sensitivity. The functions supported by the touch screen include touch, drag, pinch, and rectangle drawing.
