Safety warning
We strongly recommend that you read the general safety information below before using
your product for the first time. If the equipment is not used in the manner specified, then
the protection provided may be impaired. This could result in damage to your computer
and/or injury to yourself or others.
The USB TC-08 is designed to measure voltages in the range of ±70 mV. Any voltages in
excess of ±30 V may cause permanent damage to the unit.
Pico products are not designed for use with mains voltages.
The ground of every product is connected directly to the ground of your computer through
the interconnecting cable provided. This is done in order to minimise interference. If the
PC (especially laptop) is not grounded, reading stability cannot be guaranteed and it may
be necessary to manually ground the equipment.
As with most oscilloscopes and data loggers, you should take care to avoid connecting
the inputs of the product to anything which may be at a hazardous voltage. If in doubt,
use a meter to check that there is no hazardous AC or DC voltage. Failure to check may
cause damage to the product and/or computer and could cause injury to yourself or
Take great care when measuring temperatures near mains equipment. If a sensor is
accidentally connected to mains voltages, you risk damage to the converter or your
computer and your computer chassis may become live.
You should assume that the product does not have a protective safety earth. Incorrect
configuration or use of the device to measure voltages outside the maximum input range
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
