when used with the secondary ignition pickup leads supplied. The unit's BNC inputs
are designed to operate with voltages in the range -2 V to +2 V and are protected
against continuous or transient overvoltages of up to ±4 V. Any voltages exceeding
this may cause permanent damage to the unit, your oscilloscope or your computer.
