●
avoid personal injury and prevent damage to the
device or any products connected to it.In order to
avoid possible dangers, be sure to use this
product in accordance with the provisions in order
to avoid fire or personal injury.
Read carefully all the following safety precautions to
● Use proper power cord.Please use power cord
specified for this product and certified for use of
your country/region .
● Connect and disconnect properly.Do not connect or
disconnect probe or test leads while they are
connected to voltage source, disconnect the
testing circuit before connecting or disconnecting
the probe.
● Observe all the terminal ratings.To avoid fire or
shock hazard, please do not measure signals at
DC40V or above to avoid damage to the
device.Consult the product manual for further
rating information before making connections to
the device.
● Do not operate in wet/damp conditions.

VI. General Inspections
VII. Functional Inspections
Make a quick inspection of functions to ensure the device is working
soundly.Please perform following steps:
1.Turn on power and access to the homepage of the oscilloscope.
2. Place in the standard signal (e.g. square wave 1 KHz, Vpp=5V),
Insert X1 probe’s MCX end to CH A or CH B, and the probe to “WAVE
OUT”.Connect the oscilloscope with standard signals (e.g. square
wave1KHz, Vpp=5V), plug oscilloscope probe to the Input Channel,
set the switch on probe tip as 1X, connect the oscilloscope probe to
the Input Channel, align the probe slot with the socket and then plug
in.

VIII. Batter y 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.
When you get a new DS211 oscilloscope, you are advised to inspect
the product by the following steps.
1. 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.
2. 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.
IX. Firmware Upgrading
To upgrade the firmware of oscilloscope, please carry out the
operationfollow the steps below:
1. Open web browser to visit www.minidso.com, download the newest
firmware appropriate toof your oscilloscope to your PC.
2. Press “—” button on DS211 and switch on the Power to enter into
DFU firmware upgrading mode.
3. Use USB data cord to connect DS211 to your PC, and a removable
hard disk named：“DFU V3_60_D” 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 finished.
