1. In order to ensure the normal use of equipment, make sure to use device under the environment conditions shown in user’s manual.

2. When the probes or test cables are connecting with the power, please do not separate the probes and test cables.

3. Minimize moving the instrument to the extent possible. Handle with care. The instrument’s LCD display is the most fragile component. In order to avoid a hard shock or percussion damage, please do not move the unit when under power. Do not power off the unit and move immediately. If moving the instrument is required, remember to power off the instrument first, wait a moment and then move.

4. Avoid direct sunlight on the LCD display: Sun exposure, which not only affects the observation of the display, but can also cause premature aging of the LCD display, the display brightness reduce the LCD’s the life span.

5. Minimize the number of power-on / power-off cycles if possible. When power-on is initiated a current surge into the instrument occurs. In addition, because the circuit uses the inductive and capacitive components, an instant over-voltage / over-current phenomenon could easily damage components.

6. If a problem is found, immediately power-off the instrument. When in use, if smoke or a burning smell occurs, immediately shut down the instrument. Please contact Siglent for assistance (direct line: 877.515.5551).

7. Clean the outer portions of this instrument on a regular basis; prevent moisture erosion (moisture can not only reduce the insulation performance of high voltage components, causing ignition, cooling and other undesirable phenomena, but may also lead to corrosion and damage the copper foil of metal printing and component pins. In the extremely wet or humid conditions, the instrument should be regularly energized to operate 1 to 2 hours at a time as the internal heat can disperse the moisture.

8. Pay attention to instrument heating when in use: Under normal continuous use of 10 to 12 hours the instrument will perform as designed when it has proper ventilation and heat dissipation. But, as with all electronic components, the interior parts do have thermal limits. Keep the ventilation ports free of obstruction, avoid using the instrument placed on top of a soft cushion-type surface, and allow sufficient clearance between the instrument and a wall or other large objects which could obstruct air flow. Note that with winter use, the instrument should not be put near the heater or oven. It is recommended that the instrument is turned off and allowed to cool for approximately 30 minutes after 3 to 4 hours of continuous use.

9. For best operation of this instrument perform the oscilloscope’s self-calibration routine on a regular basis. This can help in reducing errors caused by the environment in which it is being operated.
