2.2 General Safety Information
Carefully read the following safety information in order to avoid any personal injury and damage
on this product or any products connected with it. This product can only be used in the specified
applications to prevent any possible dangers.
Warning:
To avoid fire or electrical shock. Please use proper power adapter. Use only the power
adapter appointed by the manufacturer and subject to approval of being used in the user’s
country.
Warning:
To avoid fire or electrical shock if a test tool input is connected to more 42V peak (30Vrms)
or on circuits of more than 4800VA:
●Use only insulated voltage probes, test leads and adapter supplied with the test tool, or
indicated by MEILHAUS ELECTRONIC as suitable for the Oscilloscope & Multimeter.
●Before use, inspect voltage probes, test leads and accessories for mechanical damage and
replace when damaged.
●Remove all probes, test leads and accessories that are not in use.
●Always connect the power adapter first to the AC outlet before connecting it to the
Oscilloscope & Multimeter.
●Do not apply voltages that differ more than 400 V from earth ground to any input when
measuring in a CAT Ⅲenvironment.
●Do not apply voltages that differ more than 400 V from earth ground to any input when
measuring in a CAT Ⅱenvironment.
●Do not apply voltages that differ more than 400 V from each other to the isolated input
when measuring in a CAT Ⅲenvironment.
●Do not apply voltages that differ more than 400 V from each other to the isolated inputs

●Do not use exposed metal BNC or banana plug connectors.
●Do not insert metal objects into connectors.
●Always use the Oscilloscope & Multimeter only in the manner specified.
●Voltage ratings that are mentioned in the warning are giver as limits for “working
voltage”. The represent V ac rms (50-60Hz) for AC sine wave applications and as V dc
for DC applications. Over voltage Category Ⅲrefers to distribution level and fixed

3. Performing the General Inspection
3.1 Performing the General Inspection
When you have got a new RedHand Scope series oscilloscope, it is suggested that you should
perform a general inspection on the instrument according to the following steps.
3.3.1 Check whether there is any Damage on it Due to Transportation
If the packing boxes or foam cushions are found in serous damage, keep them in a proper place till
the complete instrument and accessories have passed the electrical and mechanical tests.
3.3.2 Make a Check on Accessories
The accessory list has been described in the picture of Digital Oscilloscope Parts of this manual.
You can make a check and find whether there is any accessory loss with reference to the
Appendix. In case of any accessory loss or damage, consult the MEILHAUS ELECTRONIC
dealer responsible for such a business or the local office of MEILHAUS ELECTRONIC.
3.3.3 Make a Check on the Complete Instrument
If the instrument is damaged in its appearance or it fails in normal operation or performance test,
consult the MEILHAUS ELECTRONIC dealer responsible for such a business or the local office
of MEILHAUS ELECTRONIC. If the instrument is damaged due to transportation, keep the
packing in a proper place and consult the transportation department and the MEILHAUS
ELECTRONIC dealer responsible for such business, who will provide an instrument replacement
or maintenance.
