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 injury to yourself or others.

Maximum input range

The ADC-10 and ADC-12 are designed to measure voltages in the range 0 to +5V.

Any voltages in excess of ±30V may cause permanent damage to the unit.

The ADC-40 and ADC-42 are designed to measure voltages in the range -5V to +5V.

Any voltages in excess of ±30V may cause permanent damage to the unit.

Mains voltages

No Pico products are designed for use with mains voltages. To measure mains we

recommend the use of a differential isolating probe specifically designed for such

measurements.

Safety grounding

The ground of every product is connected directly to the ground of your computer via

the provided interconnecting cable. This is done in order to minimise interference.

Always use the provided cable to attach the product to your computer.

As with most oscilloscopes and data loggers, you should take care to avoid connecting

the ground input of the product to anything which may be at some voltage other than

ground. If in doubt, use a meter to check that there is no significant AC or DC

voltage. Failure to check may cause damage to the product and computer and could

cause injury to yourself or others.

You should assume that the product does not have a protective safety earth.

Misconfiguration or use on voltages outside the maximum input range can be

hazardous.

Repairs

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.
