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

1.1. Compliance1.1.1. 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 aredesigned 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 totake, at his own expense, whatever measures are necessary to eliminate the interference.
(FCC = Federal Communications Commission in the U.S.A.)4

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 -20 kPa ± 4 kPa.
The Leak Tester can verify a leak in a small instrument easily (Example: Micro pipette.
etc).
The amount, -20 kPa, attained by evacuating the air with the Leak Tester, is approximately
0.2 atmospheres (based on atmospheric pressure at sea level).
(100 kPa is approximately 1 atmosphere (based on atmospheric pressure at sea level).)This Leak Tester is a tool for judging leakage, and it cannot measure pressure values
accurately. The Leak Tester displays -20 kPa as a reference pressure and measuresleakage 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 ofthe 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 four 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 10000 μℓ.
