The 25MHz dual-channel oscilloscope PM 3212 is a compact, lightweight instrument, featuring ergonomic design and extensive measurement capabilities. A large 8 x 10 cm screen, with internal graticule lines, a high intensity trace together with features such as TV triggering, switchable trigger modes and adding modes for the vertical channel, make this instrument suitable for a very wide range of use. A double-insulated power supply allows the frame ground to be directly connected ro floating ground circuits provided this ground does not carry live potentials. Interference by ground currents, as is frequently experienced with grounded oscilloscopes, is also substantially reduced. Use of the oscilloscope in the field is further facilitated by optional battery operation.
