An electrical shock causing 10 milliamps of current to pass through the heart will stop most human heartbeats.Voltage as low as 35 volts dc or ac rms should be considered dangerous and hazardous since it can produce a lethal current under certain conditions. Higher voltages are even more dangerous. Your normal work habits should include all accepted practices to prevent contact with exposed high voltage, and to steer cur- rent away from your heart in case of accidental contact with a high voltage. Observe the following safety precautions: 1 There is little danger of electrical shock from the dc output of this power supply. However, there are several other possible test conditions using this power supply that can create a high voltage shock hazard: 1a If the equipment under test is the hot chassis“ type, a seri- ous shock hazard exists unless the equipment is unplugged (just turning off the equipment does not remove the hazard), or an isolation transformer is used. 1b If the equipment under test is powered up“ (and that equipment uses high voltage in any of its circuits), the power supply outputs may be fl oated to the potential at the point of connection. Remember that high voltage may appear at unexpected points in defective equipment. Do not fl oat the power supply output to more than 100 volts peak with respect to chassis or earth ground. 1c If the equipment under test is off“ (and that equipment uses high voltage in any of its circuits under normal operation), discharge high-voltage capacitors before making connec- tions or tests. Some circuits retain high voltage long after the equipment is turned off. 2 Use only a polarized 3-wire ac outlet.This assures that the power supply chassis, case, and ground terminal are con- nected to a good earth ground and reduces danger from electrical shock. 3 Dont expose high voltage needlessly. Remove housings and covers only when necessary.Turn off equipment while making test connections in high-voltage circuits. Discharge high-voltage capacitors after removing power. 4 If possible, familiarize yourself with the equipment being tested and the location of its high voltage points. However, remember that high voltage may appear at unexpected points in defective equipment. 5 Use an insulated fl oor material or a large, insulated fl oor mat to stand on, and an insulated work surface on which to place equipment; and make certain such surfaces are not damp or wet. 6 When testing ac powered equipment, the ac line voltage is usually present on some power input circuits such as the on-off switch, fuses, power transformer, etc. any time“ the equipment is connected to an ac outlet. 7 B+K Precision products are not authorized for use in any application involving direct contact between our product and the human body, or for use as a critical component in a life support device or system. Here, direct contact“ refers to any connection from or to our equipment via any cabling or switching means.A critical component“ is any component of a life support device or system whose failure to perform can be reasonably expected to cause failure of that device or system, or to affect its safety or effectiveness. 8 Never work alone. Someone should be nearby to render aid if necessary. Training in CPR (cardio-pulmonary resuscitation) fi rst aid is highly recommended.

It is prohibited to separate the safety ground connection. Most electron tubes generate X rays; the ion dose rate of this in- strument remains well below the 36 pA/kg permitted by law. In case safe operation may not be guaranteed do not use the instrument any more and lock it away in a secure place. Safe operation may be endangered if any of the following was noticed: in case of visible damage. in case loose parts were noticed if it does not function any more. after prolonged storage under unfavourable conditions (e.g. like in the open or in moist atmosphere). after any improper transport (e.g. insuffi cient packing not conforming to the minimum standards of post, rail or trans- port fi rm) Proper operation Please note: This instrument is only destined for use by person- nel well instructed and familiar with the dangers of electrical measurements. For safety reasons the oscilloscope may only be operated from mains outlets with safety ground connector. It is prohibited to separate the safety ground connection. The plug must be inserted prior to connecting any signals. CAT I This oscilloscope is destined for measurements in circuits not connected to the mains or only indirectly. Direct measurements, i.e. with a galvanic connection to circuits corresponding to the categories II, III, or IV are prohibited! The measuring circuits are considered not connected to the mains if a suitable isolation transformer fulfi lling safety class II is used. Measurements on the mains are also possible if suitable probes like current probes are used which fulfi l the safety class II. The measurement category of such probes must be checked and observed. Measurement categories The measurement categories were derived corresponding to the distance from the power station and the transients to be expected hence. Transients are short, very fast voltage or cur- rent excursions which may be periodic or not. Measurement cat. IV: Measurements close to the power station, e.g. on electricity meters Measurement cat. III: Measurements in the interior of buildings (power distribution installations, mains outlets, motors which are permanently installed). Measurement cat. II: Measurements in circuits directly connected to the mains (household appliances, power tools etc). Environment of use The oscilloscope is destined for operation in industrial, business, manufacturing, and living sites. Important hints Please check the instrument for mechanical damage or loose parts immediately after unpacking. In case of damage we advise to contact the sender. Do not operate. List of symbols used: Consult the manual High voltage Important note Ground Positioning the instrument For selection of the optimum position in use the instrument may be set up in three different positions (see pictures C,D,E). The handle will remain locked in the carrying position if the instrument is positioned on its rear feet. Move the handle to the instrument top if the horizontal operating position is preferred (See picture C). If a position corresponding the picture D (10 degrees inclination) is desired move the handle from the carrying position A towards the bottom until it engages and locks. In order to reach a position with still greater incli- nation (E shows 20 degrees) unlock the handle by pulling and move it further into the next locking position. For carrying the instrument in the horizontal position the handle can be locked horizontally by moving it upwards as shown in picture B. The instrument must be lifted while doing this, otherwise the handle will unlock again. Safety The instrument fulfi ls the VDE 0411 part 1 regulations for electrical measuring, control and laboratory instruments and was manufactured and tested accordingly.
