1.2 Safety warning
The ADC-100, like most oscilloscopes, has single ended
inputs: the ground inputs (BNC outer shell) are connected
directly to the ground of your computer. This is done in order to
minimise interference. You should take care not to connect the
ground input of the ADC-100 to anything which may be at some
voltage other than ground: doing so may cause damage to the
ADC. If in doubt, use a meter to check that there is no
significant AC or DC voltage.
The ADC-101 has differential inputs, so the ground inputs can
safely be at different potentials without the risk of a short circuit.
For computers that do not have an earth connection (for
example laptops), it must be assumed that the ADC-100/101
is not protected by an earth. For such computers, we
recommend that only class II (double insulated) oscilloscope
probes should be used.
The maximum input voltage range of the ADC-100 is ±20V.
The maximum input range of the ADC-101 is ±100V. For both
units, any voltages in excess of ±200V may cause permanent
damage to the unit.
The units contain no user serviceable parts: repair or
calibration of the unit requires specialised test equipment and
must be performed by Pico Technology Limited or their
authorised distributors.
