1. INTRODUCTION
Thank you for purchasing the AD-4532B, Digital Indicator.
This manual describes how the AD-4532B works and how to get the most out of it in terms of
performance. Please read this manual completely before using the AD-4532B.
1-1 Features
The AD-4532B has the following features.
High-speed conversion
A 2000 times-per-second high-speed A/D converter is used for inputs from sensors.
A 2000 times-per-second high-speed D/A converter is used for analog outputs.
Calibration without actual load (Digital span mode)
Keying in the sensor’s rated output voltage (mV/V) allows calibration to be performed without
using an actual load.
Various input sources
Upper and lower limit values can be input with front panel keys or by using the Modbus RTU
interface with an external computer.
The front panel keys, contact signals on the rear panel, and the Modbus port can be used for zero
adjustment and peak holding.
Hold function
Sample, peak, bottom and bipolar peak values can be held by using the hold mode.
Comparison function
Comparison results (HI, OK and LO) are output as display data and also as contact signals.
5-level comparison (2D comparator mode) is available using the comparator mode. The LED color
depends on the comparison result in the 2D comparator mode.
Various data output terminals
Analog amplifier output (AAO), D/A voltage output (DAV) and comparator output are provided as
standard with the AD-4532B.
Available options include BCD parallel output, RS-232C serial interface, analog voltage output
(DAV)/analog current output (DAI) and Ethernet interface
3-colored LED display
The 3-colored LED display, that varies with the mode or setting, is used for easier viewing.

2. PRECAUTIONS
The AD-4532B is a precision instrument. To get the most from your AD-4532B, observe the following
precautions.
2-1 Unpacking
Unpack the AD-4532B carefully and confirm that everything is contained. Keep the packing material
if you want to transport the indicator again in the future.
2-2 Precautions Before Use
Avoid water and moisture.
Avoid vibration, shock, extremely high temperature and humidity, direct sunlight, dust, and air
containing salt or sulfurous gases.
Avoid places where inflammable gases or vapors are present.
The operating temperature is -5°C to +40°C.
The power requirement is 85 VAC to 250 VAC. Use a stable power supply free from
instantaneous dropout or noise. Avoid sharing with the power line.
Connect a grounding wire to the ground terminal. Do not share grounding with other units that
create electrical noise.
Keep cables sensitive to electrical noise away from power cables and other sources of
electrical noise.
Connect a non-inductive load of 5 kΩ or more to the analog output terminals.
Use 6-wire shielded cables to connect sensors. If 4-wire cables are used, connecting long
cables to the sensors will increase the total cable resistance and cause measurement errors.
Keep these cables away from power cables and other electrically noisy cables
Do not connect the AD-4532B to the power supply before installation is completed. The
AD-4532B has no switch to disconnect the power supply.
Use shielded input/output cables. Connect the cable shield to the FG terminal or the indicator
housing.
4
2-3 Precautions During Use
The AD-4532B is a precision instrument that measures the microvolt output from sensors.
Prevent noise sources such as power lines, radios, electric welders or motors from affecting
the instrument.
Do not try to modify the AD-4532B.
In any hold mode, the hold data is saved in a digital manner, causing no drooping of the value
displayed on the display panel or the analog output. Note that the hold function is disabled
when the AD-4532B is disconnected from the power supply.
During calibration, both no-load and actual load input must be stable. If the inputs are unstable
from the moment the 1↵
key is pressed to the moment the next data is displayed, a
calibration error will occur.
Disconnect from the power supply before removing the cover
When removing the cover, make sure that the power is off.
Do not touch the instrument immediately after it is disconnected from the
power supply.
To avoid electrical shock, do not touch the internal part of the instrument within ten
seconds after the power is off.
Be sure to fasten all the screws completely.
Loose screws may come off during operation and a short circuit may occur. Or
measurement errors may occur due to noise.

6-2 Description of Functions
6-2-1 Input filter
An analog low pass filter which removes noise in the inputs from the sensors. A pass band can be
selected from 3 Hz, 10 Hz, 30 Hz, 100 Hz, 300 Hz and 1 kHz in function mode f-01.
6-2-2 Analog amplifier output
The sensor’s analog signals are amplified 625 times and the analog amplifier output (AAO) outputs
the amplified signal directly. Therefore, scaling is not available.
Output example
When the excitation voltage is 5 V and the sensor output is 3.2 mV/V,
the analog output value will be:
3.2 mV/V x 5 V x 625 ≈10 V.
Analog output errors
As scaling is not available for the analog output, the output value varies depending
on the indicator. Before use, be sure to check the output values of the sensors.
6-2-3 Moving average filter
Filter which averages the measured values converted from analog to digital. The number of moving
average is set in function mode f-02. The maximum number of moving average is 254.
Select a small value when high-speed measurements are required, and a large value when stable
measurements are required.
6-2-4 Digital filter
A high-speed processor controlled, high-performance digital filter. The cutoff frequency value is set in
function mode f-03.
Select a high frequency when high-speed measurements are required and a low frequency when
stable measurements are required.
6-2-5 External input
The AD-4532B has nine external inputs, ZERO, HOLD, LATCH, COMP ON, COMP 1 to COMP 5
(5-level comparator). Maintain the inputs for more than 10 ms.
6-2-6 Hold
As digital filtered data is used, high-speed hold is enabled. A hold mode can be selected from
sample hold, peak hold, bottom hold and bipolar peak hold in function mode f-14.
15
6-2-7 DAV output
The DAV output is the measured value in digital format, converted to an analog output voltage.
A DAV output mode can be selected from output without holding or output after holding in function
mode f-24. Scaling is available in function modes f-22 and f-23.
6-2-8 BCD parallel output
The BCD parallel output is the measured value converted into a BCD format. The output logic can
be selected from positive or negative in function mode f-32. An output rate can be selected from 1
time/s, 10 times/s, 100 times/s, 1000 times/s or 2000 times/s in function mode f-33.
6-2-9 Comparator and comparator output
The comparator judges the measured values using the upper/lower limit values and the comparator
output outputs the comparison results.
A comparator mode can be selected in function mode f-16.
A zero band setting can be selected in function mode f-17.
The comparator has a comparator hysteresis function and the values used can be set in function
modes f-19 to f-21.
6-2-10 Modbus RTU
The AD-4532B has Modbus RTU protocol. The values that the AD-4532B indicates and the
AD-4532B status can be read and the set values of the AD-4532B can be written, using Modbus
RTU.
This is used, for example, to read measured values or change the settings when connecting the
AD-4532B to a personal computer, PLC or programmable display
16
7. CALIBRATION
The AD-4532B measures voltage signals from sensors and displays the values. Calibration is
performed on the AD-4532B so that it performs correctly.
7-1 Description of Calibration
Calibration has the following setting items and operations.
Minimum division setting
Selects the minimum division.
Rated capacity setting
Sets the rated capacity.
Zero calibration
Adjusts the indicator so that the measured value will be zero
when no load is applied to the load cell.
Span calibration
Adjusts the indicator so that it can correctly measure the change
in the input voltage generated by loading the load cell.
Notes on calibration
The setting range of output resolution is less than 10000. Even if a value exceeds
10000, it will be displayed.
Perform a periodic check to confirm that the indicator measures correctly. And
perform calibration as necessary.
When the installation site is changed, confirm that the indicator measures correctly,
and perform calibration as necessary.
When performing span calibration using a calibration weight, use a weight having a
mass of more than two-thirds of the maximum measured value to minimize
calibration errors.
Wait for the indicator to stabilize before calibration to ensure correct measurements.
To use the decimal point, use function mode f-00.
17
7-2 Calibration Modes
There are three calibration modes.
Digital span mode (d-5p)
The sensor’s rated output voltage is keyed in. Calibration is performed without using an actual
load.
Calibration mode (Cal)
Zero and span calibration are carried out using an actual load.
Full calibration mode (fCal)
Zero and span calibration are carried out using an actual load after minimum division and rated
capacity have been set.

9. HOLD FUNCTION
The AD-4532B has four hold modes; sample hold, peak hold, bottom hold and bipolar peak hold. A
hold mode can be selected in function mode f-14.
9-1 Basic Operation
9-1-1 Starting a hold mode
Four methods to start a hold mode are available.
Using the HOLD key
Pressing the HOLD key will start the hold function and display the held value.
Pressing the HOLD key again will stop the hold function and display the measured value.
Using the external HOLD input terminal on the rear panel
Turning ON (contact input) the HOLD input terminal will start the hold function.
Turning OFF the HOLD input terminal will stop the hold function.
Using Modbus
Activating the Modbus coil address 1 will start the hold function.
Activating the Modbus coil address 2 will stop the hold function.
Using the optional RS-232C command
The RS-232C hold ON command “H CR LF” will start the hold function.
The RS-232C hold OFF command “C CR LF” will stop the hold function.
HOLD indicator
When the hold function is started, the HOLD indicator turns on to indicate that the hold function is
activated. In the hold modes other than the sample hold mode, the PEAK indicator turns on when
the peak value (or bottom value) is reached.
Priority
The priority of the hold input using the external HOLD input terminal is higher than the other
methods.
Holding time after releasing hold
The AD-4532B has a function to hold the value for a certain period of time after the hold function is
stopped. To set the holding time, use function mode f-15.
During the holding time, the HOLD indicator blinks.
When the set holding time is elapsed, the display switches to the currently measured value.
When starting the hold function during the holding time, the indicator holds the new value.
Using the holding time
Use this function to confirm the held value.
While the displayed value is held, the indicator continues other operation using the
latest measured value.

10. COMPARATOR FUNCTION
The AD-4532B has two comparator modes; simple comparator and 2D (Two dimensional)
comparator. A comparator mode can be selected in function mode f-16. f-17 to f-21 are also
comparator-related function modes.
The comparator function compares the measured value against the set value and outputs the
comparison results (HI, OK or LO) from the rear panel comparator output terminals.
10-1 Simple Comparator Mode
Compares the measured value against the upper or lower limit value and outputs the comparison
results from the rear panel comparator output terminals.
The operation of the simple comparator mode can be set using the parameters 0 to 3 of function
mode f-16.
10-1-1 Detailed description of the simple comparator mode
The relation between the output results and the output condition is as shown below:
Comparator output terminal
Output condition
HI
Upper limit < Measured value
OK
Lower limit ≤ Measured value ≤ Upper limit
LO
Measured value < Lower limit
When function mode f-18 (COMP ON) is set to “0 (Not used)”, the comparator functions
according to the f-16 parameter setting (0 to 3).
When function mode f-18 (COMP ON) is set to “1 (Used)”, connect the COMP ON input terminal
to the IN COM terminal to enable the comparator.
The upper/lower limit values saved, even if the power is off, are maintained in non-volatile
memory.
Upper limit and lower limit values can be negative.
For example, if the upper limit value is -1000 and the lower limit value is -2000, HI is output for the
measured value of -500 and LO is output for the measured value of -2500.
Make sure that the upper limit value is greater than the lower limit value.
32
10-1-2 Setting the upper and lower limit values
1. In the measurement mode, press the HI key or LO key to check the
upper limit value or lower limit value.
2. In the main display,

Number of digits available in the display
Each sub-display is a five-digit display. Therefore, it can not display the complete
value if the upper limit or lower limit value has six digits (or five digits for the
negative value).
To check the upper limit or lower limit value, follow the procedure above to display
the value in the main display, a six-digit display.
Zero band value
Set the zero band value in function mode f-17.
The zero band ranges from 0 to ±(absolute zero band value).

COMP ON input and output
HI, OK or LO output is available only when the COMP ON input terminal is ON
(when the COMP ON input terminal is connected to the IN COM terminal). When
the COMP ON input terminal is OFF, no comparison nor result output is performed.
To make a continuous comparison, set the function mode f-18 (COMP ON) to “0
(Not used)”.
Zero band and output
When the measured value is less than the zero band value, HI, OK or LO output is
not available even if the COMP ON input terminal is ON.
The zero band ranges from 0 to ±(absolute zero band value) that is set in
function mode f-17.
For example, when f-17 is set to 200, the zero band is from –200 to 200.
34
10-2 2D Comparator Mode
The 2D (Two dimensional) comparator mode performs a two dimensional comparison by switching
the 5-level comparator with the upper and lower limit values that are preset for each level.
10-2-1 Switching the comparator
Two switching methods are available.
By COMP 1 to COMP 5 inputs (f-16 4 or 5)
Switching is performed by the change in position.
Connect the position detection switch to the COMP 1 to COMP 5 input terminals. Set function
mode f-16 (Comparator mode) to “4” or “ 5”.
By time control (f-16 6 or 7)
Switching is performed by the change in time.
In addition to the upper and lower limit values, set the starting and ending time to each level of the
comparator. Set function mode f-16 (Comparator mode) to “6” or “ 7”.
10-2-2 Detailed description of the 2D comparator mode
Turn the COMP ON input terminal ON to start a comparison. With the COMP ON input terminal
turned OFF, no comparison or result output is performed. To use the COMP ON input terminal, set
the function mode f-18 (COMP ON) to “1 (Used)”.
The relation between the output results, the indicator color and the output condition for each level
is as shown below:
Comparator output terminal
HI
OK
LO
Comparator
indicator
z Red
z Green
z Orange
Front panel (part)
Output condition
Upper limit < Measured value
Lower limit ≤ Measured value ≤ Upper limit
Measured value < Lower limit
5-level comparator indicators
A number is written above each z to
indicate the level.
When the COMP ON input terminal is
turned ON, the z indicator, at the level
where the comparison is performed
currently, starts to blink. Then, the
indicator turns to red for HI, green for OK
and orange for LO. When the comparison
moves to another level, the indicator
stops blinking and illuminates in the color
of the result.
NG indicator
In the 2D comparator mode, the NG
indicator turns on when any one of the
5-level comparison results is HI or LO.
The NG indicator is red when HI, and
orange when LO. When the comparison
results of levels 1 through 5 have HI and
LO, it will be red.

10-5 2D Comparator Mode (Additional Explanation)
While the conventional comparison method detects and judges the maximum or minimum value only
during measurement, the 2D comparator mode uses contact inputs from the rear panel terminals or
elapsed time to make a comparison at various levels.
This type of comparison is useful for an operation such that the pressure increases rapidly at the
pressurization starting time and changes in pressure occur during the pressurization process.
Using this mode, an erroneous situation such as the fall over of a rivet which receives the pressure
or assembling error due to the wrong mounting holes can be detected accurately.

10-6 Comparator Hysteresis Function
A hysteresis width and time is provided for the output relay on/off timing to prevent the output
terminals from chattering.
When the measured value exceeds the set value, the relay is turned on. If the measured value falls
below the set value and it is further reduced by the hysteresis width, or if the hysteresis time has
elapsed, the relay is turned off.
The hysteresis mode, time and width can be set in function modes f-19, f-20 and f-21.
10-6-1 Upward 2-level judgment (f-19 0)
Relation between OK and HI
When the measured value exceeds the set upper limit value, HI is output. Even if the measured
value falls below the upper limit value after that, OK is not output immediately. OK will be output
when the measured value is reduced by the hysteresis width, or when the hysteresis time has
elapsed.
Relation between OK and LO
Even if the measured value falls below the set lower limit value, LO is not output immediately. LO
will be output when the measured value is reduced by the hysteresis width, or when the
hysteresis time has elapsed.
When the measured value returns above the lower limit value, OK is output immediately.

Relation between OK and LO
When the measured value falls below the set lower limit value, LO is output. Even if the measured
value returns above the lower limit value after that, OK is not output immediately. OK will be

11. ANALOG OUTPUT
The AD-4532B has two types of analog output; the analog amplifier output (AAO) that amplifies the
sensor’s analog signals and outputs the amplified signal, and the digital to analog voltage output
(DAV) that processes the measured values from the sensors according to the values set in function
mode, and outputs the processed signal as a voltage after D/A conversion.
These outputs are used to observe the voltage waveform from the sensors by connecting a recorder
to the analog output terminal.
11-1 Analog Amplifier Output (AAO)
Amplifies the sensor’s analog signals 625 times and outputs the amplified signal. The output voltage
range is from –10 V to +10 V. The pass band can be changed in function mode f-01.

Output example
When the excitation voltage is 5 V and the sensor rated output is 3.2 mV/V,
the analog output value will be:
Sensor output voltage = 3.2 mV/V x 5 V = 16 mV.
Analog amplifier output voltage = 16 mV x 625 ≈10 V.
Note: The output voltage varies depending on the indicator. Before use, be sure to check
the output values of the sensors.

11-2 Digital to Analog Voltage Output (DAV)
Processes the measured values from the sensors according to the values set in function modes
f-22 to f-24, and outputs the processed signal as a voltage after D/A conversion. The output
voltage range is from –10 V to +10 V. Scaling is available in function modes f-22 and f-23.

Note on using this function
Use this mode only when adequate accuracy can not be obtained by the regular
scaling set in function modes f-22 and f-23. This mode uses the internal
correction factor and requires a high-precision digital multimeter. If a low-precision
multimeter is used, it may adversely affect the indicator performance and the output
voltage accuracy.

15-3 AD-4532B-07 Analog Voltage/Current Output (DAV/DAI)
The DAV/DAI analog voltage/current output is an interface to output the values displayed by the
AD-4532B as an analog voltage or analog current. The analog output range for voltage is from –10 V
to +10 V and for current, from 4 mA to 20 mA.
An analog voltage output from -10 V to +10 V or analog current output from 4 mA to 20 mA can be
obtained according to the values set in function modes f-34 and f-35.
A fine adjustment is available for either one of DAV or DAI.
The output circuit is electrically isolated from the indicator circuit.

15-3-2 Fine adjustment of zero and span
Note on using this function
Use this mode only when adequate accuracy can not be obtained by the regular
scaling set in function modes f-34 and f-35. This mode uses the internal
correction factor and requires a high-precision digital multimeter. If a low-precision
multimeter is used, it may adversely affect the indicator performance and the output
voltage accuracy.
Zero and span adjustment of the AD-4532B DAV/DAI are not performed
externally but internally in a digital manner. Voltage is used for adjustment.
