功能 检查

● When you get a new DS202 oscilloscope, you are advised to

inspect the product by the following steps.

● Inspect damages caused by shipping.
If the packaging carton or the protection pad is seriously damaged,

keep the package until the oscilloscope & accessories pass the
electrical and the mechanical test.

● Inspect the product.
Please contact the company if the following problems occur: 1)

product surface is damaged, 2) product doesn't work properly, 3)
product does not pass performance test.

If the damage is resulted from shipping, please keep the package

and contact the company for repair or exchange.

● Make a quick inspection of functions to ensure the device is working

soundly. Please perform following steps:

● Turn on power and access the homepage of the mini oscilloscope.

● Connect the oscilloscope with standard signals (e.g. square wave

20KHz， Vpp=5V), set the switch on probe tip as 1X, plug
oscilloscope probe to the Input Channal.Check whether the
measured signal value is the same as the standard value; it can be
calibrated if the margin is small.
