9. MAINTENANCE AND GUARANTEE

The

N24 and

N25 digital panel meter series do not require

any periodical maintenance.

In case of some incorrect operations:

During the Guarantee Period:

One should take the meter down from the installation and

the anufacturer.

After the Guarantee Period:

One should

The disassembling of the casing causes the cancellation of the

granted guarantee.

Our policy is one of continuous improvement and

we reserve the right to make changes in design and

speci

ﬁ
