1. SAFETY PRECAUTION
The A oscilloscope is easy to operate and highly reliable. It is an ideal instrument for research, production, education, and development. It is a compact and portable oscilloscope with a frequency bandwidth of 10MHz and sensitivity of 5mV/DIV-5V/DIV. Supplied as standard, with a switchable X10: X1 probe which extends the sensitivity up to 50V/div. The horizontal timebase is 0.1S/DIV to 0.1µS/DIV.
The instrument is designed and tested in accordance with EN publication 61010, CAT II, Pollution degree II and Overvoltage 600V. The instrument has been tested in accordance to the following EC Directives (EMC) :
a.EN50082
b.EN55011
c.EN610000-3-2
d.EN61000-3-3
The instrument complies with the requirements of the European Council Directive 89/336/EEC (EMC Directive) and 73/23/EEC (Low Voltage Directive). To ensure that the instrument is used safely, follow all safety and operating instructions in this manual. If the instrument is not used as described in this manual, the safety features might be impaired.
WARNING
Non compliance with the warnings and/or the instructions for use may damage the instrument and/or its components or injure the operator.
Take extreme care under the following conditions when using the instrument:
For your own safety and that of the instrument, you must follow the procedures described in this instruction manual and especially read all the notes proceeded by the symbol 
carefully.
Do not use this instrument in a location where there is explosive gas in the vicinity. The use of this instrument in a location where there is explosive gas could result in explosion.
If there is any smoke, abnormal odor, or abnormal sound coming from this instrument, immediately switch off the power and disconnect the power cord. Continuous using of this instrument under these conditions could result in electrical shock or fire. After disconnecting the power cord, contact the service offices for repair. Repair by the user is
2
dangerous and should be strictly avoided.
Take care not to allow water to get into this instrument. The use of this instrument in a wet state could result in electrical shock or fire. If water or other foreign matter has penetrated this instrument, first switch the power off, remove the power cord and call for repair.
Do not place this instrument on an unstable or slanting surface . The dropping or turning over of this instrument could result in electrical shock, injury or fire. If this instrument has been dropped or its cover has been damaged, switch the power off, remove the power cord and call for repair.
Do not allow any foreign matter such as metal or inflammable substance to get into the instrument via the air holes. The penetration of any foreign matter from the ventilation holes could result in fire, electrical shock, or power failure.
Use this instrument with the rated AC power source. Use of this instrument with a voltage other than specified could result in electrical shock, fire or power failure. The usable power voltage range is marked on the rear panel.
Do not remove either the cover or panel.
Take sufficient care when measuring high voltages.
Do not modify this instrument.
Avoid use of damaged cables .
