1. Safety Precautions
This product complies with the requirements of the following European Community Directives: 2004/108/EG
(Electromagnetic Compatibility) and 2006/95/EG (Low Voltage) as amended by 2004/22/EG (CE-Marking).
Overvoltage category II; pollution degree 2.
To ensure safe operation of the equipment and eliminate the danger of serious injury due to short-circuits
(arcing), the following safety precautions must be observed. Damages resulting from failure to observe these
safety precautions are exempt from any legal claims whatever.
* Do not use this instrument for high-energy industrial installation measurement.
* Do not place the equipment on damp or wet surfaces.
* Do not exceed the maximum permissible input ratings (danger of serious injury and/or destruction of the
equipment).
* The meter is designed to withstand the stated max voltages. If it is not possible to exclude without that
impulses, transients, disturbance or for other reasons, these voltages are exceeded a suitable presale
(10:1) must be used.
* Disconnect test leads or probe from the measuring circuit before switching modes or functions.
* Check test leads and probes for faulty insulation or bare wires before connection to the equipment.
* To avoid electric shock, do not operate this product in wet or damp conditions.
* Conduct measuring works only in dry clothing and rubber shoes, i. e. on isolating mats.
* Never touch the tips of the test leads or probe.
* Comply with the warning labels and other info on the equipment.
* The measurement instrument is not to be to operated unattended.
* Do not subject the equipment to direct sunlight or extreme temperatures, humidity or dampness.
* Do not subject the equipment to shocks or strong vibrations.
* Do not operate the equipment near strong magnetic fields (motors, transformers etc.).
* Keep hot soldering irons or guns away from the equipment.
* Allow the equipment to stabilize at room temperature before taking up measurement (important for exact
measurements).
* Do not input values over the maximum range of each measurement to avoid damages of the
instrument.
* Periodically wipe the cabinet with a damp cloth and mid detergent. Do not use abrasives or solvents.
* The meter is suitable for indoor use only
* Warning:
To avoid fire or electrical shock, when the oscilloscope input signal connected is more than 42V peak
(30Vrms) or on circuits of more than 4800VA, please take note of below items:
- Only use accessory insulated voltage probes and test lead.
- Check the accessories such as probe before use and replace it if there are any damages.
- Remove probes, test leads and other accessories immediately after use.
- Remove USB cable which connects oscilloscope and computer.
- Do not apply input voltages above the rating of the instrument because the probe tip voltage will directly
transmit to the oscilloscope. Use with caution when the probe is set as 1:1.
- Do not use exposed metal BNC or banana plug connectors.
- Do not insert metal objects into connectors.
