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 Ω or more to the analog voltage output terminals.

Connect only a non-inductive load of 510 Ω 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.

1-

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.

7. CALIBRATION

The AD-4531B measures voltage signals from sensors and displays the values. Calibration is performed so that the AD-4531B performs correctly.

The decimal point (Cf-01), minimum division (Cf-02) and rated capacity (Cf-03) are set using the function mode.

The zero point input voltage (Cf-04), the span input voltage (Cf-05) and the displayed value for the span input voltage (Cf-06) are adjusted using the calibration mode.

Calibration setting using the function mode is also available. (Digital span)

* During calibration, maintain a stable environment to prevent calibration errors.

* When the measured value is stable, the HOLD LED is turned on.

* The decimal point blinks to indicate that the current value is not a measured value.
