1. BEFORE USE
The AD-4531B digital indicator is a precision instrument. Unpack the
digital indicator carefully and confirm that all items are present.
1.1. Precautions Before Use
The AD-4531B is a precision instrument. Handle it with much care.
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 range is –10 °C to +40 °C.
A 100 VAC to 240 VAC power source is required. Use a stable
power supply free from sudden dropout or noise as they can cause
malfunctions. Avoid sharing the power line.
Keep cables away from power cables and other sources of
electrical noise.
Connect only a non-inductive load of 10 k or more to the analog
voltage output terminals.
Connect only a non-inductive load of 510 or less to the analog
current output terminals.
When connecting long cables to the sensors, keep the cables
away from power cables and other sources of electrical noise
Do not connect the AD-4531B to the power supply before
installation is completed. The AD-4531B has no switch to turn the
power off.
Use shielded load cell cables.
Do not connect too many sensors. Otherwise, instrument damage may occur.
1.2. Precautions During Use
The AD-4531B 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-4531B.
In all hold modes, the hold data is saved digitally, so there is no
drooping of the value displayed on the display panel or the analog
output. Note that the hold function is disabled when the AD-4531B
is disconnected from the power supply.
Disconnect from the power supply before removing the cover.
When removing the cover, make sure that the power is
disconnected.
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 disconnecting from the power supply.
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.

4.2. Installing an Option
1. Remove the two screws that secure the guide rail, and then remove the
guide rail.
2. Remove the two screws that secure the case.
Pull the case out of the front panel (holding it as shown).
4. Remove unnecessary blank panels with nippers, etc.
5. Insert the option board at the position specified on the rear of the front
panel.
6. Reattach the case and guide rail by reversing the steps above.
5. FRONT PANEL
5.1. Display
Displays a measured or set value. To set the decimal point position, use
the function mode Cf-01. The display is composed of six seven-segment
LEDs plus a minus sign.
5.2. Status Indicators
Name Description
1 HI
Turns on when the measured value is greater than the
upper limit (HI).
2 OK
Turns on when the measured value is equal to or greater
than the lower limit and equal to or less than the upper
limit.
3 LO
Turns on when the measured value is less than the
lower limit (LO).
4 DZ Turns on when adjusting the zero value. (Digital zero)
5 HOLD Turns on when a value is being held.
5.3. Keys
Operation Function
Press to proceed to the upper limit value
setting mode.
When inputting a numerical value, press to
change the polarity.
Press to proceed to the lower limit value
setting mode.
When inputting a numerical value, press to
cancel the setting.
Press to turn the digital zero function on.
When inputting a numerical value, press to
shift the position of the blinking digit to the
right or change the function group.
+
Press to turn the digital zero function off.
Press to turn the hold function on or off.
When inputting a numerical value, press to
change the blinking digit or change the
function parameter.
Press to output the serial data (print).
When inputting a numerical value, press to
enter the setting.
+
Press to proceed to the calibration mode.
+
Press to proceed to the function selection
mode.
+ +
Press to proceed to the selection mode in
the check mode.
* The digital zero function sets a desired measurement point as zero and
displays the deviation from this zero point. When weighing a load, it can
be used as the tare, etc.
* The zero value is saved in non-volatile memory (EEPROM) and is
maintained even if the power is disconnected.
* To change the zero adjustment operation, use the function Cf-11.
To protect against accidental operation, press and to
turn the digital zero function on or off.
