1 Introduction
This manual describes how the AD-1641 works and how to maximize
performance. Please read this manual completely before using the AD-1641.
This device conforms to FCC rules and CE mark EMC directives.
1.1 Features
■ The AD-1641 is a data logger equipped with 5 sensors: air flow, temperature,
humidity, barometric pressure and vibration. Air flow sensor part is independent
from the instrument and can be installed to any desired location for
measurement.
 By connecting the output of the AD-1641 to the RS-232C of the insutrument, it
is possible to record weighing data and environmental data sets so data can be
saved without the computer.
■ The AD-1641 has a built-in clock. This allows the date and time to be stored
along with the data.
■ A maximum of 10,000 data can be stored.
■ The environmental data is stored in CSV format and can easily be used by
software such as spreadsheet applications.
■ The stored data can be read by a computer after the AD-1641 is recognized as
USB memory so no special software is required.
■ The AD-1641 can transmit data to programs in the computer (Ex: Excel, etc)
using the USB interface. (Real time transmission mode)
■ When connecting any combination of weighing instrument or computers, the
power is supplied for the AD-1641 by them. In this case, AD-1641 batteries are
not used.
1.2 Caution During Use
When operating this instrument, be sure to observe the following.
■ Do not open the case to repair the AD-1641. Only authorized personnel can
perfrm repairs. Attempting repairs yourself may cause damage to the AD-1641.
and will void the warranty.
 When the battery cover and temperature & humidity sensor unit are connected
to the AD-1641 and the connectors are firmly seated in the water resistant
connector covers, the AD-1641 is protected against light water exposure
(equivalent to IP 65). Please note that the water resistance will not endure
immersion in water or high pressure runnning water.

Air flow can only be
measured from the
front.
4 How to use
Step 1 Install the air flow sensor unit in an arbitrary location.
( Since there are two M4 screw holes in the bottom of the Air Flow
sensor, it can be fixed to the floor surface .)
Step 2 Connect the air flow sensor and the main unit with the cable.
Step 3 Turn on the power.
 In the case of the AC adapter:
The power turns on automatically. Select「EXT.POWER」, press ENTER key.
 In the case of battery drive:
When pressing and holding the ON/OFF key,the AD-1641 will turn on.
For inserting of batteries, please refer to the "9.Replacement for batteries
and Sensor Unit".
Step 4 The basic operation will use the keys below:
 SELECT key (Press):
Switches the display.
 START/STOP key(Press):
Starts the interval recording,and the REC sign will be displayed.
 START/STOP key (Hold down):
Stops the interval recording, and the REC sign will be turned off.
 ON/OFF key (Hold down):

Turn off the AD-1641 (except during the interval recording or when power is
supplied from a source other than batteries)
Note
 If the air flow sensor is not connected to the main unit, air flow cannot be
measured. "AF" is only displayed when the air flow sensor cable is connected.
■ The air flow sensor only measures air flow that comes from the front.
■ If the measurement value is not zero when there is no air flow calibrate the
AD-1641 referring to "calibration of wind speed values" in "5.Air Flow Calibration"
before using the AD-1641.
■ The air flow measurement battery life is approximately 20 hours.
■ Display turn off time can be changed in the "time to display off (POWER SAVE)"
of "7.4.Internal settings." If there has been no operation for over one minute, the
display will turn off automatically when battery power is being used.(The factory
setting)
■ During the interval recording, should the recording data memory become full, the
interval recording stops automatically and, the power is turned off.(The factory
default recording system "FUNCTION" setting is "ONE-TIME".)
 Temperature and humidity sensor unit is replaceable (life approximately 2 years).
