Description
Overview
GAOTek Infrared Thermometer with Non-Contact Design (Alarm Setup) supports low and high temperature alarm setup function and can be used to measure the temperature of an object’s surface (hot, hazardous, or hard-to-reach objects) quickly, safely, and directly without contact. This device consists of optics system, photoelectric sensor, signal amplifier, signal process circuit and LCD. The optics system collects the infrared energy emitted by the object and focuses it onto the sensor which then translates the energy into electric signals which are displayed as readings on the LCD by the signal amplifier and signal process circuit. This device is also equipped with RS-232 data export function and is suitable for industrial temperature test.

Distance to spot size
When taking measurements, pay attention to the Distance to Spot Size. As the Distance (D) from the target surface increases, the spot size (S) of measuring area becomes larger.
The Distance to Spot Size of the unit is 80:1.
This device is equipped with a laser which is only used for aiming.
Field of view
Make sure the target is larger than the unit’s spot size.
The smaller the target, the smaller is the measuring distance.
When accuracy is critical, make sure the target is at least twice as large as the spot size.
Operation
Turn ON/OFF
Install/replace battery:
Open the battery door and insert 9 V alkaline battery correctly. Then close the battery door.
Turn ON/OFF:
Pull the trigger until a “Bi….Bi..” sound appears. The unit turns off automatically if there is no further operation in 30 seconds.
Locate hot/cold spot:
To find a hot/cold spot, aim the thermometer outside the area of interest, then scan across with up and down motion until you locate the hot/cold spot.
Measurement:
- Trigger: pull the trigger to turn on, LCD displays VERXX software version for 1 second, and the temperature reading. SCAN and EMS (pre-set emissivity 0.95) displays at the same time. Release the trigger, the temperature will be held automatically, LCD will display the temperature reading and HOLD icon.
- Laser and backlight ON/OFF: when the backlight turn on, any operation will remain backlight for 7 seconds. LCD indicates laser / backlight ON/OFF status. Pressing this button again and again will change the status of laser/backlight.
- Mode selection: press MODE button, LCD displays in the sequence of PLY-CLR-MAX-MIN-AVG-DIF-HAL-LAL-SNG-EMS (note: under the mode of EMS, HAL, and LAL, press the SET button first, when the mode flashes, press up /or down button to set up, finally press SET to confirm)
- Illustration of modes:
PLY: Replay the stored data. When PLY is selected, press up or down button to Check the data.
CLR: Clear stored data. Press STO/CAL button for 2 seconds, the stored data will be all cleared.
MAX: Measure maximum temperature.
MIN: Measure minimum temperature.
Average: Measure average temperature.
DIF: Based on the reading before press SET button to compute the difference of current reading.
HAL: High temperature alarm—when selected HAL, press up or down button to set high temperature alarm trigger and confirm by pressing SET button. When the reading over trigger, LCD displays HI icon with BiBi audio sounds.
LAL: Low temperature alarm— when selected LAL, press up or down button to set low temperature alarm trigger and confirm by pressing SET button. When the reading is over trigger, LCD displays LOW icon with BiBi audio sounds.
EMS: Adjust the emissivity from 0.1 to 1.0.
Data storage:
- When taking measurement, every pressing on STO/CAL button will save a data, which has the max capacity of up to 4000 data.
- When taking measurement, pressing STO/CAL button and pulling the trigger continually allows you to save the sampling data continually.
Data review:
- In PLY mode, press UP/DOWN button to replay the data.
- Pressing SET button and UP/DOWN button at one time allows you to review data quickly. Or you may connect the product with PC to export the data.
Data clearance:
In the CLR mode, press STO/CAL button for 2 seconds to clear the stored record.
Lock/unlock:
In measuring, press on the trigger and the SET button at one time to enter into continuous measuring mode; a lock icon appears on the LCD during this operation; when trigger is pressed again to exit continuous measuring mode, unlock icon appears on the LCD during this operation.
Unit selection:
Open the battery door and slide the switch to change the temperature unit.
RS-232 connection with PC:
- When the product is properly connected with PC, there is DATA displaying on the LCD.
- Please refer to the file IRT instructions in the disk included to install the program.
- Program function: to retrieve data, to save online/offline and data curve analysis.
DC IN:
Use the 9V 500 mA DC adaptor to save battery consumption.
