GYS GM300 Infrared thermometer Instruction Manual

Infrared thermometer
Instruction manual Version：380-EN-01

Introduction

This infrared thermometer is used for measuring the temperature of the object’s surface, which is applicable for various hot, hazardous or hard-to- reach objects without contact safely and quickly. This unit consists of Optics, Temperature Sensor Signal amplifier, Processing circuit, and LCD Display. The Optics collected the infrared energy emitted by the object and focus it onto the Sensor. Then the sensor translates the energy into an electrical signal. This signal will be turned out to be digital shown on the LCD after the signal amplifier and pro- cessing circuit.

Warning & Cautions

1. Warning:
   To avoid the potential situation that may cause harm or damage to people, please pay attention to the following items:
   1.  Before you use this unit, check on the plastic housing carefully. If there is any damage, do not use it.

2. Do not point the laser directly at eye or indirectly off reflective surfaces.
3. Do not use this unit in an environment of explosive gas, steam, or dust.

2. Caution: To avoid damage of the unit or the target, please protect from the following situations:
   1). EMF (electromagnetic fields) from arc welders and induction heaters.
   2). Thermal shock (caused by large or abrupt ambient- ent temperature changes- allow 30 minutes for the unit to stabilize before use.
   3). Do not leave the unit on or near objects of high temperature

Distance to Spot size

1. When take measurements, pay attention to the Distance to Spot Size. As the Distance (D) from the target surface increases, the spot size (S) of the area measured by the unit becomes larger. The Distance to Spot size of the unit is 12:1
   ***This unit is equipped with a laser, which is used for aiming.

2. Field of view:
   Make sure the target is larger than the unit’s spot size. The smaller the target the closer the measure dis- tance. When accuracy is critical, make sure the target is at least twice as large as the spot size.

Emissivity

Most organic materials and painted or oxidize- ed surfaces have an emissivity of 0.95 (pre-set in the unit). Inaccurate readings will result from measuring shiny or polished metal surfaces. To compensate, cover the target surface with masking tape or flat black paint. Measure the tape or painted su- face when the tape or painted reaches the same temperature as the material underneath.

Operation

1.  Operating the unit：

1. Open the battery door and insert a 9V battery properly.；
2. Pull the trigger to turn on the unit;
3. Aim at the target surface and pull the trigger, then the temperature will be shown on the LCD. This unit is equipped with a laser, which is only used for aiming.

2. Locating a Hot Spot：
To find a hot spot, aim the thermometer outside interest, then scan across with an up and down motion until you locate the hot spot. (Figure 3)

1. Trigger: When pulling the trigger, the LCD displays readings with the SCAN icon. Release the trigger, and display- ay reading with the HOLD icon for 7 sec(approx). Built-in 20 sec auto power-off function.
2. Laser on/off button
3. Celsius / Fahrenheit switch button
4. The backlight on/off button: When the backlight is on, any operations will activate the backlight for 7 seconds.

Maintenance

1. Lens Cleaning:
   Blow off loose particles using clean compressed air. Gently brush the remaining debris away with a moist cotton swab. The swab may be moistened with water.

2. Case cleaning: Clean the case with a damp sponge/cloth and mild soap.

Note:

1. Do not use solvent to clean the plastic lenses.
2. Do not submerge the unit in water.
