FAQ 5.
 
TCT series
 

 

  
 
Imagine a butcher testing the temperature of meat. The probe will burst off the plastic holding it!
 
IR Thermometer is applied in food service for business purpose more then home. If customers would like to use them, we will strongly recommend them to measure the temperature with certain distance or after cooling (not while cooking). After all, most users will use it for food storage temperature more frequently- spot check like FDA.
 
What it the advantage to use TCT series then probe?
 
The TCT series is both a stainless steel probe and an infrared thermometer that allows you to simply point at whatever you're cooking to get a temperature read. Although infrared temperature readers are less accurate than probes, they allow professional inspectors to test a lot of food without coming in contact with it. That way, there's less cleanup and danger of cross-contamination.
When you pull the unit out , it looks like an ear magnifier without the cone tip attached. Press  the measuring button and the infrared beam glows in front, instantly producing a temperature reading on the display screen if you happen to be pointing at anything. The pointed probe flips down from the handle.
If measuring by infrared, hold the gun 1 to 10 inches away from your target, which needs to be at least 1/2 inch in diameter. If there's smoke or steam, hold the unit back and at an angle to avoid interference.  When using the probe, hit the Select button to switch to the probe function, insert the tip at least 1/2 inch in, and hold it while the probe graphic flashes on the display; when the probe beeps, the temperature shows on the display.
Of course, never shine the infrared beam in your eyes. It won't instantly blind you, but staring into the beam at close range might temporarily damage your sight. You can safely shine the beam elsewhere. You might want to do as they do in professional kitchens: Shine the light on each other's asses to see whose is "hottest."

TN2 series
 
Why the LCD display show low battery or battery dead already but laser still working?
 
Yes. The reason is because in TN265L and TN205L use 2 CR2032 battery. 1 is used for laser function and another is for LCD/temperature reading. So even the temperature cant read but laser still works.  There is no such problem in TN253L model.
 
 

 

  
 
TN1 series
 
The unit does NOT shut off after 15 seconds and the unit remains running. Why?
 
1)Check if you are in "Lock" Mode.
There shall have "Lock" icon on the LCD display between time and readings.  If Yes, then it will keep measure up to 1 hour without stop. Or you can press the measure/scan button 1 time, then the lock mode will be off. If No, please refer below for another solution.
2) Take off the battery out of unit and wait for 30 sec. to 1 min then insert the battery back. The unit shall be back to original default -  reset to 0 for everything. Then you can make decision if you would like to have "clock mode" on (by setting time) or not.
If yes, you would like to have clock mode on. If you don't touch the measure button for 15 sec., the reading will switch to room temperature not keep reading. If no, the whole complete unit will turn off / shut down after 15 sec.
