1. Introduction
Thank you for purchasing Apacer AL100/AL110 Spectroradiometer! To fully enjoy the benefits of this
product, please read the important information and instructions in this manual carefully and keep it in an
easily accessible place for future reference.
Please make sure you read the following safety instructions thoroughly to avoid harming yourself or
damaging your spectroradiometer before, during, and after using this product.
Power supply: Power can be supplied to the spectroradiometer via an AC adaptor or a computer
connected to the instrument via a USB cable. However, to make sure the unit runs smoothly, we
recommend using the AC adaptor that comes with the package.
Environment: Keep away from an area with a high dust or humidity level and corrosive gases. Make
sure the environment does not experience abrupt changes in temperature; otherwise, measurement
accuracy can be highly affected.
Vibration and collision: The spectroradiometer is equipped with highly sophisticated optical
components. To prevent it from falling or collision, do not place it near any moving objects while
operating; keep it safe in a box while carrying it around.
Dust ingression: Wipe off dust and dirt with towels or silica cloth. Do not use any chemicals, such as
diluents, acetone, or volatile solvents which may damage the spectroradiometer.
Storage: Place the spectroradiometer in a tool box under normal temperature. Do not put it in cars or
expose it to environment with high temperature, humidity, or dust.
Calibration: A measuring instrument like spectroradiometer may fail to produce valid data after being
used for a period of time. To ensure optimum accuracy, we recommend you send the instrument back
to the original manufacturer for calibration on a yearly basis. Please contact Apacer or your dealer for
detailed information.
Maintenance: Never dismantle the spectroradiometer by yourself. If encountering any breakdowns,
please contact your dealer or the original manufacturer for assistance.

3. Getting Started with Spectroradiometer
This chapter explains how to use your AL100/AL110 Spectroradiometer without being connected to a
computer via a USB cable and ASR, desktop application designed for AL100/AL110 Spectroradiometer,
start up and zero calibrate the device, view system information, manage settings for the instrument,
manage measuring methods, and view measurement data.
3.1. Starting up and Calibrating the Spectroradiometer
To ensure measurement accuracy, we suggested you calibrate the spectroradiometer upon every system
startup. Follow the steps below to start the calibration.
To start up and calibrate your spectroradiometer:
1. Long press the power button on the device to power on.
2. Cover the lens with the lens cap to start calibrating the device, and do either of the following:
Tap Continue to calibrate the unit.
Tap Skip if you do not want to perform calibration now. You may calibrate the unit later by going to
Setting. See “Managing Settings”for more information.

status, do either of the following:
Successfully calibrated: You can start measuring the spectrum of light source by tapping
Measure on the device screen or press the physical Measure button on the side of the unit.
However, in case you want to configure system settings before measuring in order to capture
results data as accurately as possible, tap Setting. See “Managing Settings”for more information.
Calibration failed: The calibration results can be affected by potential error sources such as
external lighting during a calibration. If ambient lighting is detected, an error message will appear.
Please make sure the lens is covered with the lens cap, and tap Continue to perform the
calibration once again.
