Safety warnings
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 injury to
yourself and others.
DO NOT exceed the maximum input range.
The PT-104 Data Logger is designed to
measure voltages in the range 0 to +2.5 V. Any voltages in excess of ±30 V may
cause permanent damage to the unit.
DO NOT use in contact with mains (line) voltages.
This product is not designed
for use on circuits carrying mains voltages. Take great care when measuring
temperatures near mains (line-powered) equipment. If in doubt, use a meter to check
that there is no hazardous AC or DC voltage on the equipment. If a sensor is
accidentally connected to a mains voltage, you risk damage to the converter and your
computer, and your computer chassis may become live resulting in injury to yourself
and others.
DO NOT exceed the maximum input voltage range of the device.
Incorrect
configuration or use of the device to measure voltages outside this range can be
hazardous.
DO NOT rely upon the product's ground connection as a protective safety
earth.
If there is any possibility of contact with hazardous voltages, the equipment
under test must be safely earthed.
DO NOT attempt to repair 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 or its authorised distributors.
