The conformity test made by HAMEG is based on the actual generic- and product stan- dards. In cases where different limit values are applicable, HAMEG applies the severer standard. For emission the limits for residential, commercial and light industry are applied. Regarding the immunity (susceptibility) the limits for industrial environment have been used. The measuring- and data lines of the instrument have much infl uence on emmission and immunity and therefore on meeting the acceptance limits. For different applications the lines and/or cables used may be different. For measurement operation the following hints and conditions regarding emission and immunity should be observed: 1. Data cables For the connection between instruments resp. their interfaces and external devices, (computer, printer etc.) suffi ciently screened cables must be used. Without a special instruction in the manual for a reduced cable length, the maximum cable length of a dataline must be less than 3 meters and not be used outside buildings. If an interface has several connectors only one connector must have a connection to a cable. Basically interconnections must have a double screening. For IEEE-bus purposes the double screened cables HZ72S and HZ72L from HAMEG are suitable. 2. Signal cables Basically test leads for signal interconnection between test point and instrument should be as short as possible. Without instruction in the manual for a shorter length, signal lines must be less than 3 meters and not be used outside buildings. Signal lines must screened (coaxial cable - RG58/U). A proper ground connection is required. In combination with signal generators double screened cables (RG223/U, RG214/U) must be used. 3. Infl uence on measuring instruments. Under the presence of strong high frequency electric or magnetic fi elds, even with careful setup of the measuring equipment an infl uence of such signals is unavoidable. This will not cause damage or put the instrument out of operation. Small deviations of the measuring value (reading) exceeding the instruments spe- cifi cations may result from such conditions in individual cases. 4. RF immunity of oscilloscopes. 4.1 Electromagnetic RF fi eld The infl uence of electric and magnetic RF fi elds may become visible (e.g. RF superimposed), if the fi eld intensity is high. In most cases the coupling into the oscilloscope takes place via the device under test, mains/line supply, test leads, control cables and/or radiation. The device under test as well as the oscilloscope may be effected by such fi elds. Although the interior of the oscilloscope is screened by the cabinet, direct radiation can occur via the CRT gap. As the bandwidth of each amplifi er stage is higher than the total 3dB bandwidth of the oscilloscope, the infl uence RF fi elds of even higher frequencies may be noticeable. 4.2 Electrical fast transients / electrostatic discharge Electrical fast transient signals (burst) may be coupled into the oscilloscope directly via the mains/line supply, or indirectly via test leads and/or control cables. Due to the high trigger and input sensitivity of the oscilloscopes, such normally high signals may effect the trigger unit and/or may become visible on the CRT, which is unavoidable. These effects can also be caused by direct or indirect electrostatic discharge.

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. General information 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 As can be seen from the fi gures, the handle can be set into diffe- rent positions: A = carrying B = handle removal and horizontal carrying C = horizontal operating D and E = operating at different angles F = handle removal T = shipping (handle unlocked) Attention! When changing the handle position, the instru- ment must be placed so that it can not fall (e.g. placed on a table). Then the handle locking knobs must be simultaneously pulled outwards and rotated to the required position. Without pulling the locking knobs they will latch in into the next locking position. Handle mounting/dismounting The handle can be removed by pulling it out further, depending on the instrument model in position B or F. Safety The instrument fulfi ls the VDE 0411 part 1 regulations for electrical measuring, control and laboratory instruments and was manufactured and tested accordingly. It left the factory in perfect safe condition. Hence it also corresponds to
