General Inspections
When you get a new DS211 Mini Oscilloscope, you are advised to inspect the product by the following steps.
- Inspect damages caused by shipping. If the packaging carton is seriously damaged, keep the package until the oscilloscope & accessories pass the electrical and the mechanical test.
- Inspect the product. Please contact the dealer if the following problems occur to DS211: 1) product appearance is damaged, 2) product doesn't work properly, 3) product does not pass performance test. If the damage to DS211 is resulted from shipping, please keep the package.
Functional Inspections
Make a quick inspection of functions to ensure the device is working soundly. Please perform following steps:
- Turn on power and access to the homepage of the oscilloscope.
- Place in the standard signal (e.g. square wave 1 KHz, Vpp=5V), Insert X1 probe's MCX end to "INP” channel, and the probe to "OUT" channel. Check if the measurement value and the standard value are equal, calibrate if different.
Battery Charging Instructions
When the battery voltage status turns to "?" or display brightness is relatively dim, please charge the battery in time; charging is workable in both power-on and off mode.
Firmware Upgrading
To upgrade the firmware of oscilloscope, please carry out the operation follow the steps below:
- Visit www.miniware.com.cn, download the firmware to your PC appropriate DS211.
- Hold “—” button on DS211 and switch on the Power to enter DFU firmware upgrading mode.
- Use USB data cord to connect DS211 to your PC, and a removable hard disk named: “DFU X.XX" will appear on your PC; copy the hex firmware to the root directory of that disk, after the extension of the firmware changes from "hex” to “rdy”, restart DS211, and then the upgrading process is completed.
Buttons and Interface
The device features ports for Signal Input (INP), Signal Output (OUT), and USB connection. The front panel includes buttons for Power, Stop, Up, Left, Right, Down, and Menu (M).
