1. INTRODUCTION

This manual describes how the AD-1690 Leak Tester works and how to get the most out of it in terms of performance. Read this manual thoroughly before using the Leak Tester and keep it at hand for future reference.

1.1. Compliance

Compliance with FCC Rules

Please note that this equipment generates, uses and can radiate radio frequency energy. This equipment has been tested and has been found to comply with the limits of a Class A computing device pursuant to Subpart J of Part 15 of FCC rules. These rules are designed to provide reasonable protection against interference when the equipment is operated in a commercial environment. If this unit is operated in a residential area, it may cause some interference and under these circumstances the user would be required to take, at his own expense, whatever measures are necessary to eliminate the interference.

(FCC = Federal Communications Commission in the U.S.A.)

Compliance with EMC Directives

This device features radio interference suppression in compliance with

valid EC Regulation 2004/108/EEC.

2. FEATURES

- This Leak Tester judges a leak by a pressure change, after the initial pressure is set

inside the instrument, to a maximum of -20kPa ± 4kPa.

The Leak Tester can verify a leak in a small instrument easily (Example: Micro

pipette. etc).

The amount, -20kPa, attained by evacuating the air with the Leak Tester, is

approximately 0.2 atmospheres (based on atmospheric pressure at sea level).

(100kPa is approximately 1 atmosphere (based on atmospheric pressure at sea

level).)

This Leak Tester is a tool for judging leakage, and it can not measure pressure

values accurately. The Leak Tester displays -20kPa as a reference pressure and

measures leakage as a pressure change from this amount.

This Leak Tester is designed to test the leakage of a pipette or dispenser and prevent

foreign particle from invading the Leak Tester when evacuating the air at the nozzle of the

instrument.

This Leak Tester is protected against invading dust by an air filter located on the

main unit bottom side.

The accessories provide attachments for three different pipettes tip sizes.

You can select an attachment where the tip and pipette size match up.

With the Micro pipette, the available test capacity is up to 10000μℓ.
