cables, software and examples. Features include:
Built in sensors for light, sound (level and waveforms) and temperature
Measure pH - just plug in our standard pH electrode
Sockets for external sensors
Use DrDAQ to capture fast signals (for example, sound waveforms)
Digital output for control experiments
Simply plug in to your PC and measure - supplied with both PicoScope (oscilloscope)
and PicoLog (data logging) software

Safety warning
DrDAQ ground is connected directly to the ground of your computer. As with most
oscilloscopes and data loggers, this is done in order to minimise interference. You should
take care not to connect the ground (screw terminal, outer shell of BNC or exposed
metalwork) of DrDAQ to anything which may be at some voltage other than ground: doing
so may cause damage to the unit. If in doubt, use a meter to check that there is no
significant AC or DC voltage.
For computers that do not have an earth connection (for example, laptops), it must be
assumed that DrDAQ is not protected by an earth (in the same way a battery multimeter
is not protected by an earth).
The maximum input voltage range of any input is 0 to 5V. Any voltage in excess of ±30V
may cause permanent damage to the unit.
The unit contains 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.
