Chapter 1. Safety Precautions
1.1 Safety Precautions
The following safety precautions must be understood to avoid personal injury and prevent damage to this product or
any products connected to it. To avoid possible safety hazards, it is essential to follow these precautions while using
this product.
⚫Only professionally trained personnel can operate the maintenance procedure.
⚫Avoid fire and personal injury.
⚫Use proper power cord. Use only the power cord specified for this product and certified for the country/region
of use.
⚫Connect and disconnect probes properly. Connect the instrument probe correctly, and its ground terminal is
ground phase. Do not connect or disconnect probes or test leads while they are connected to a voltage source.

2
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.

Chapter 1. Safety Precautions
3
⚫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.
⚫Keep product surfaces clean and dry.
⚫The disturbance test of all models complies with Class A standards, based on EN61326:1997+A1+A2+A3,
but do not meet Class B standards.
Measurement Category
The STO1000 series oscilloscope is intended to be used for measurements in Measurement Category I.

4
Measurement Category Definition
Measurement category I is for measurements performed on circuits not directly connected to the MAINS. Examples
are measurements on circuits not derived from MAINS, and specially protected (internal) MAINS derived circuits.
In the latter case, transient stresses are variable; for that reason, the user must understand the transient withstand
capability of the equipment.
Warning
IEC Measurement Category. Under IEC Category I mounting conditions, the input terminal can be connected to the
circuit terminal with a maximum line voltage of 300Vrms. To avoid the risk of electric shock, the input terminal
should not be connected to the circuit with a line voltage greater than 300Vrms. Instantaneous overvoltage is
present in circuits that are isolated from the mains supply. The STO1000 series digital oscilloscope is designed to
safely withstand sporadic transient overvoltage up to 1000Vpk. Do not use this equipment for any measurements in
circuits where the instantaneous overvoltage exceeds this value.
