Introduction

Please contact us if you need help, if you have a complaint, or if you have  suggestions to help
us improve our products or services.

If you contact us about a product you already have, please tell us the full  model number and
serial number, so that we can give you  accurate and fast help.

This product has  a 2 year warranty. We will put right or replace any meter which is faulty
because of  bad workmanship or materials. This warranty does not cover damage caused by
misuse or accident.

If you return a unit for repair, please include a detailed description of the problem, and the
name of a contact who we can refer to for any questions. Please mark for the attention of the
QA Department.

IMPORTANT

If this equipment is important to your process, you may want to buy a spare to cover possible
failure or accidental damage in the future.

This is because during factory shutdown periods, you may have to to wait several weeks for
an equivalent replacement, or we may have no stock at the time you urgently need it.

You may also need to pay extra carriage charges if you want a fast, guaranteed courier  service.
Warranty repairs or replacements are usually returned with a standard courier service.

We do not offer compensation for losses caused by failure of this instrument.

If you do not agree with these conditions, please return this item in unused, condition, in its
original packaging and we will refund the purchase price, excluding any carriage paid.

We thought you’d  prefer to know about possible delays and extra charges now, rather than
during a panic. A spare unit could help to avoid these issues.

We always try  to improve our products and services, so these may change over time. You
should keep this manual safely, because future manuals, for new designs, may not describe
this product accurately.

We believe these instructions are accurate, and that we have competently designed and
manufactured the product, but please let us know if you find any errors.
