Installation and Precautions
Installation and PrecautionsInstallation and Precautions
3.1. Installation and Precautions
The AD-4406 weighing indicator is a precision electronic instrument. Handle the
indicator carefully.
The operating temperature is -10 to +40 (14 to 104 ).
Do not install the indicator in direct sunlight.
A malfunction or other problems may be caused by an unstable power source including
momentary power failure or instantaneous noise. Use a stable power source.
When an AC Adapter is used, please confirm that the local voltage and receptacle type
are correct for your indicator.
Use shielded cables for all connections. Connect the cable shields to the shield
terminal or case as an earth terminal.
Earth ground the indicator. Do not join the earth ground line with other electrical
power equipment.
Do not install the indicator in a place where it is apt to be charged with static
electricity, or where the relative humidity is lower than 45%RH. Plastic and isolators
are apt to be charged with static electricity.
3.2. Power Supply
When an AC adapter is used
A stable power source must be used; an unstable power source which includes an
instantaneous noise component may result in a malfunction.
When dry batteries are used
Use fresh batteries, preferably alkaline type. Insert batteries into the battery box (use
caution in inserting to match the polarity of the batteries), and insert the battery box
with the contacts to the inside of the indicator. Push it in and towards the bottom.
The battery box will hook onto the edge of the case. Install the cover over the battery
box so that it will not fall out.
To remove the battery box, press in and up on the end of the battery box. Slowly
release pressure on the battery box while holding it against the top of the battery
compartment and the battery box will slide out.
The AD-1681 rechargeable battery pack can be used in place of the standard battery
box.
AD-4406 Weighing Indicator Page 5
3. Installation and Precautions
3.3. The Load Cell Connections
Connect the load cell wires to the connector (receptacle), at the rear panel, using the
accessory load cell plug.
It is possible to connect a 4 wire cable provided that pins 1-2 and pins 3-4 are
shorted, if the distance between the indicator and a load cell is shorter than 5m.
The output voltage of a load cell is a very sensitive signal. Place the load cell cable
away from any noise source.
It is possible to connect four 350 ohm load cells.
The load cell drive is 5VDC 5% between EXC+ and EXC-, the maximum current 60 mA.
3.4. Adjustment of the Load Cell Output
Caution Use a metal film resistor in the range of 50kohm to 500kohm with a good
temperature coefficient, when adding a resistor to adjust a load cell
output. Use the largest resistance value possible in the range in which
zero adjustment is possible. Solder this resistor at a point near the load
cell or the indicator.
In Case of Reducing the Output Voltage
When the zero output is too large, add a resistor
between EXC+ and SIG-.
In Case of Adding an Offset Voltage to the Output
When the zero output is too small, add a resistor
between EXC+ and SIG+.
3. Installation and Precautions
Page 6 AD-4406 Weighing Indicator
3.5. Verifying Load Cell Output and Input Sensitivity
The input sensitivity of the indicator is 0.2 µV/division or more. Adapt to the following
inequality, when you design a weighing instrument using the indicator and load cell(s).
Caution A change in input voltage sensitivity is required to cause a one division
change in the display. Select as large an input sensitivity voltage as
possible so that the weighing interval becomes stable.
Consider the leverage if a lever is used.

5.1. Items of the Calibration Mode
There are four items in the calibration function where setting should be done.
How to calibrate: In weighing mode, press the CAL key which is located behind the
CAL cover at the lower right of the front panel. After CAL in is displayed for 2
seconds CAL 0 will appear. The required items should be selected and displayed
with the ZERO key, then executed by pressing the ENTER key.
* The CAL cover is removed by sliding downward.
Required Items

Sets capacity, resolution, decimal point position and
display format, weighing range and unit. These items
should be set first in order for the indicator to function
as a weighing instrument. Set values do not need to
be changed again unless the indicator itself is
replaced. For details, refer to “5.2.1. Configuring a
Weighing Instrument”.

CAL Writes all the set data into non-volatile memory and displays CALoFF after the
ON/OFF key is pressed. Note that the ON/OFF key does not function alone.
Press the ESC key while holding the ON/OFF key to end the calibration mode
when a value is mistakenly set. After CAnCEL is displayed, pressing the
ON/OFF key stops the calibration mode and turns the indicator off.
Caution The maximum display is less than or equal to 40000 divisions. This number
is calculated from the maximum capacity divided by the minimum division.
Check the accuracy of weighing instrument periodically.
Recommended mass, use a mass heavier than 2/3 maximum capacity.
Calibrate the scale, if it is moved to another location or the environment
has changed.
It is not necessary to set the gravity acceleration correction, when calibrating
the scale with a calibration mass at the place where the scale is used.
Enter the stable weight data while the STABLE mark is displayed. If
unstable data is used, it may cause a weighing error. Arrange the
condition using the F00 filter function.
The span calibration needs the zero calibration data. We recommend that
you perform the span calibration immediately after the zero calibration.
If you use the dual range function of the multi-interval scale, perform the
"Range Function", "Zero Calibration" and "Span Calibration".

5.3.1. Setting the Division and Range
Consider the following rules to design the weighing range.
Rule 1 Select the division and range of each weighing range so as to fit the following inequality.
The first range < the second range
The division of the next weighing range is automatically set larger than the division
of the lower weighing range.
Rule 2 When setting the dual range, the upper limit value of the second range becomes
the maximum capacity.
Rule 3 Select a resolution smaller than 40000. The resolution is a value obtained by
dividing the maximum capacity by the minimum division of the first range.

5.4. Digital Linearization Function
5.4.5.4.
Even if the zero and span calibration have been completed, there may still remain a
linearity deviation caused by the performance of the weighing unit. The digital
linearization function can rectify or reduce the linearity deviation using weighing points
during the zero and capacity setting. Up to three weighing points can be specified.

Caution This function does not improve repeatability or hysteresis.
Use the mass on the condition that Lnr 1 < Lnr 2 < Lnr 3.
Do not press the ENTER key while the STABLE mark is off.
Step 1 Check the CAL 0 display. Press the key to display Lnr 0.
Step 2 Enter the zero point. Refer to “5.2.8. Zero Calibration”.
Step 3 The value of the middle point is displayed after indicating Lnr x. x is 1, 2 or 3.
The mark of the same number (x) is displayed along with the value.
Step 4 Select a middle point.
If you want to cancel the current procedure, press the ESC key to finish this
function. Proceed to step 7 and the other points are cleared (canceled).
Select a middle point value using the following keys. Proceed to step 5.
key ..........To select a digit.
key...........To select a value.
Step 5 Place a mass equivalent to the displayed value on the weighing unit. Press the
ENTER key after the STABLE mark has turned on. Proceed to step 6.
Step 6 If you include a 2nd and 3rd middle point, repeat steps 3, 4, 5 for each.
If you finish this function, proceed to step 7.
Step 7 Perform step 11 of "5.2.9. Span Calibration" immediately.
