A warning shows that if the operation does not

comply with the following correct instruction, it is

possible to bring hazards to the user or cause

damage to the calibrator in use. The warning also

points out how to avoid the accidents.

Note

A note serves as a sign to remind the user that he

must understand the correct operation of the

calibrator and its characteristics.

To prevent the user and the calibrator from any electric shock and

other hazards, it is necessary to observe the following regulation:

Warning

Warning

Warning

Warning

It is not allowed to operate the calibrator at the working

field where there exists flammable gas or explosive gas or

vapor. It is very dangerous to operate the calibrator in

such a surrounding.

Never apply more than 30V between any two terminals, or

between any terminal and earth ground.
