ground phase. Do not connect or disconnect probes or test leads while they are connected to a voltage source.
Disconnect the probe input and the probe reference lead from the circuit under test before disconnecting the
probe from the measurement product.
⚫Ground the product. To avoid electric shock, the instrument grounding conductor must be connected to
earth ground.
⚫Observe all terminal ratings. To avoid fire or shock hazard, observe all rating and markings on the product.
Consult the product manual for further information of ratings before making connections to the product.
⚫User correct probes. To avoid excessive electric shock, use only correct rated probes for any measurement.
⚫Disconnect AC power. The adapter can be disconnected from AC power and the user must be able to access
the adapter at any time.
⚫Do not operate without covers. Do not operate the product with covers or panels removed.
⚫Do not operate with suspected failures. If you suspect that there is damage to this product, have it inspected
by service personnel designated by Micsig.
⚫Use adapter correctly. Supply power or charge the equipment by power adapter designated by Micsig, and
charge the battery according to the recommended charging cycle.
⚫Avoid exposed circuitry. Do not touch exposed connections and components when power is present.
⚫Provide proper ventilation.
⚫Do not operate in wet/damp conditions.
⚫Do not operate in a flammable and explosive atmosphere.

Measurement Category
ATO series oscilloscopes can be measured under measurement category I.
Measurement Category Definition
Measurement category I is for measurement on a circuit that is not directly connected to the mains power supply. For
example, there is no circuit drawn from the main power source, or a circuit that has been drawn from the mains but has
been specially protected (internal). In the latter case, the instantaneous stress will change; therefore, the user should
understand the instantaneous endurance of the device.
Warning:
IEC measurement category. Under IEC category I installation conditions, the input terminal can be connected to a
circuit terminal with a maximum line voltage of 300Vrms. To avoid the risk of electric shock, please do not connect
the input terminal to a circuit whose line voltage exceeds 300Vrms. The transient overvoltage exists in a circuit
isolated from the main power supply. TO1000 series digital oscilloscopes are designed to safely withstand
occasional transient overvoltages up to 1000Vpk. Do not use this equipment to measure in a circuit where the
instantaneous overvoltage exceeds this value.
1.2 Safety Terms and Symbols

Chassis Ground Measurement Ground Terminal
Please read the following safety precautions to avoid personal injury and prevent damage to this product or
any products connected to it. To avoid possible hazards, this product can only be used within the specified
scope.
Warning
If the instrument input port is connected to a circuit with the peak voltage higher than 42V or the power exceeding
4800VA, to avoid electric shock or fire:
⚫User only insulated voltage probes supplied with the instrument, or the equivalent product indicated in the
schedule.
⚫Before use, inspect voltage probes, test leads, and accessories for mechanical damage and replace when
damaged.
⚫Remove voltage probes and accessories not in use.
⚫Plug the battery charger into the AC outlet before connecting it to the instrument.

Figure 2-5 Basic Operations of tBook mini series Oscilloscope
Tap
Tap button on the touch screen to activate the corresponding menu and function. Tap any blank space on the screen
to exit the menu.
Swipe
Single-finger swipe: to open/close menus, including main menu, shortcut menu button and other channel menu
operations. For example, the main menu is opened as shown in Figure 2-6. The closing method is the opposite of
the opening method.

16
Figure 2-6 Slide out of Main Menu
Tap the options in the main menu to enter the corresponding submenu.
The opening methods of channel menu and math menu are slightly different from that of the main menu. Tap the
channel icon and math icon to open the corresponding menu.
Three-finger slide: to quickly turn on/off Zoom. Refer to “3.5 Zoom Mode” for details.
Four-fingers slide: for quick screen capture. Refer to “7.1 Screen Capture Function” for details.
Single-finger drag: For coarse adjustments of vertical position, trigger point, trigger level, cursor, etc. of the
waveform. Refer to “3.1 Horizontal Move Waveform” and “4.3 Adjust Vertical Position” for details.
2.8 Mouse Operation
Connect the mouse to the “USB Host” interface, then operate the oscilloscope with the mouse. The menu will pop
up with the right mouse button. The left mouse button has the same function as the finger touch, and the horizontal
time base can be adjusted by rolling the mouse wheel. The right mouse button menu is shown in Figure 2-7.
Figure 2-7 Mouse Cursor
Note: The touch operation cannot be used normally after the mouse is connected (unless it is unlocked, see 12.9 Shut
down, lock screen and unlock for details)
2.9 Connect Probe to the Oscilloscope
1) Connect the probe to the oscilloscope channel BNC connector.
2) Connect the retractable tip on the probe to the circuit point or measured equipment. Be sure to connect the
probe ground wire to the ground point of the circuit.

Maximum input voltage of the analog input
Category I 300Vrms, 400Vpk.
2.10 Use Auto
Once the oscilloscope is properly connected and a valid signal is input, tap the Auto Set button to quickly
configure the oscilloscope to be the best display effects for the input signal.
Auto is divided into Auto Set and Auto Range. It is defaulted as Auto Set.6
Auto Set — Single-time auto, and each time press “Auto”, the screen displays “Auto” in the upper left corner. The
oscilloscope can automatically adjust the vertical scale, horizontal scale and trigger setting according to the
amplitude and frequency of signals, adjust the waveform to the appropriate size and display the input signal. After
adjustments, exit from the auto set, the “Auto” in the upper left corner disappears.
Channels may be automatically opened. Any channel greater or less than the threshold level can be opened or closed
automatically according to the set threshold level. The threshold level can be settable.
Source can be automatically triggered, and the triggered source channel can be automatically set to select priority
to the current signal or to the maximum signal.
Open the main menu. Tap “Auto” to open the auto set menu, including channel open/close setting, threshold voltage
setting and trigger source setting.
Figure 2-8 Open Auto Set
Automatic configuration includes: single channel and multiple channels; automatic adjustment of the horizontal
time base, vertical sensitivity and trigger level of signal; the oscilloscope waveform is inverted off, the bandwidth
limit sets to full bandwidth, it sets as DC coupling mode, the sampling mode is normal; the trigger type is set to
edge trigger and the trigger mode is automatic.
Note: The application of Auto Set requires that the frequency of measured signal is no less than 20Hz, the
duty ratio is greater than 1% and the amplitude is at least 2mVpp. If these parameter ranges are exceeded,
Auto Set will fail.
