11 SAFETY AND MAINTENANCE
11.1 General maintenance
Always store the glossmeter in its case when it is not in use.
Make sure the device is placed correctly in the case with the display facing the front.
Never use pressurized air to clean the meter.
Maintaining the screen
Handle the device with care and make sure that you do not accidentally scratch or break the LCD screen. Do
not bang the TQC Sheen Glossmeter or expose it to extreme temperatures. Temperatures above 50°C will
damage the display. This is a real danger when, for example, the glossmeter is left in the car.
Cleaning the TQC Sheen Glossmeter
We recommend cleaning the instrument with a soft, dry cloth such as that used to clean glasses. Do not use
solvents! Clean the plastic housing only with isopropyl alcohol and a dry cloth.
Cables and connections
The TQC Sheen Glossmeter can be connected to the PC by a USB cable. Never force a connector that is
difficult to insert in the connection. Make sure the connector and the connection fit together and that they
are aligned and undamaged. The buttons on the TQC Sheen Glossmeter are disabled when the device is
connected to a PC. The message USB ATTACHED Buttons disabled displays on the screen.
Heat, humidity, and dust
Keep the TQC Sheen Glossmeter away from extreme heat. Do not leave the device near a heater or in the car
on the dashboard. Heat can damage the screen, the plastic housing, and the internal components.
Do not leave the device in dusty, humid, or wet places. Dust and humidity can damage the device and cause
defects/failures.
11.2 Calibration
The TQC Sheen Glossmeter automatically emits a signal when it needs calibrating. For more information on
calibration, see section 4.3.
The calibration value must be adjusted when the calibration holder is changed. The calibration values can be
found next to the glass plate in the calibration holder. Because the value can differ for each calibration holder,
it is important that a glossmeter is always calibrated on the same calibration holder. The calibration values
can be adjusted when the calibration holder is replaced.
11.3 Batteries
The top-right corner of the Glossmeter screen displays a battery, indicating the remaining battery life. When
the batteries almost need replacing, the battery symbol in the measurement/scan window starts blinking.
We recommend using only high-quality batteries. Battery type: AA 1.5 V alkaline (not rechargeable). Insert
the + side of the battery first and then press down the – side.
Check the time and date after replacing the batteries.
