Warning: Be careful not to input excessive power voltage
- The input power capacity is fixed as shown below to prevent electric shock and/or Please DO NOT use voltage higher than that prescribed below.
Warning: Be sure to check the probe attenuation before measuring the voltage. The voltage that is higher than the maximum input voltage can cause damage to the device and you. In particular, there is the risk of an electric shock when measuring high voltage. So you need to pay extra attention not to have your hand touch the terminal.
- Please eliminate all unused probes or tester leads so that they do not come in contact with surrounding high voltage parts.
- Make sure that the PC’s power source is grounded.
- The probe ground lead is at ground potential. Do not connect the ground lead to an elevated voltage. Connect the ground lead of the probe to earth ground only.
If measuring the floating potential, we will recommend the measurement by the differential motion method using CH1 and CH2.
- Do not connect or disconnect the product with the probe or test lead which is connected to a voltage source.
- Do not attempt to operate the product at the situation that a risk of dysfunction or shock expected to happen.
- Stop using the product immediately when you notice something unusual about the smell, smoke or sound.
- And then remove the USB connection form your computer.
- Keep the product out of the reach of children or those who cannot be trusted with the use.
- Do not use the product with your hands wet. It can cause an electric shock.
- Do not try the product for the purposes other than those stated.
- If the products crevice is exposed to electric conductors (solids or liquids), the product will short circuit and possibly create dangers of electric shock or fire. Please keep this product away from humidity, water, or dust.
- DO NOT use this product near gas as well as other flammable and/or explosive materials.
- Store the product where direct sunlight can’t reach.

Minimum System Requirements
To install and run the USB, you should have the following.
Microsoft Direct X supported
Screen resolution: 800 x 600
Colour depth: 16 bit
- When manufactured, the USB is calibrated manually to obtain maximum performance.
- You may calibrate the USB 5 or 6 months after purchase.
- You must use a probe with more than 100 MHz bandwidth to get undistorted signal.
- Probe should be compensated whenever it is connected for the first time.
- Connect calibration signal to channel 1, and then push AUTOSET.
- Check the shape of the displayed waveform.
- Adjust the probe until the displayed waveform is compensated.
