Portable Infrared Thermometer

JDIT-130-N(Temperature: -60 to 550 ℃)

JDIT-130-N Operating Instructions
The thermometer is a non-contact infrared thermometer. There are many mathematical modes for theInfrared function. Please remember to keep away from children and don’t use it for safety relatedapplications(Default Screen)
Simply aim the thermometer at themeasure target with Lens (9) andpress Meas. Key (7) to display thesurface

temperature.

TheDistance:Spot is 12:1. Please makesure the target area is within thefield of view.

Function
Press Mode key (2) for scrolling more display function as follows.
Here will show the emissivity data. (The default emissivity is 0.95)
Press Mode key (2), then press Lock key (4) or ℃/ ºF key (3) to set the emissivity, then press
Mode key (2) to confirm it. The emissivity can be changed from 0.10 (10E) to 1 (100E).
Press Mode key (2) for the Maximum (MAX), Minimum (MIN), Different between MAX andMIN (DIF) and Average (AVG) modes. During the measurement, the special modes reading
will be displayed beside the mode icon.
Press Lock key (4)or ℃/ ºF key (3) to change the High Alarm (HAL) or Low Alarm (LAL), thenpress Meas. key (7) to confirm it. When the reading is outside the High Alarm (HAL) or Low
Alarm (LAL) limit. The High or Low icon will flash and you will hear a beep sound.

ADD VALUEIn E, MAX, MIN, DIF,
AVG mode:

Press Lock key (4) for LOCK mode ON/OFF. The lock mode is particularly useful forcontinuous monitoring of temperatures for up to 60 minutes.
Press ℃/ ºF key (3) for ℃ or ºF transferred

In all modes: First holdand press Lock key (4) for backlight function ON/OFF.

on the Meas. key (7)and press ℃/ ºF key (3) for laser function ON/OFF.

MemoryMemory Recall the last reading memory by pressing Mode key (2) while power off.

CAUTION
1. WHEN DEVICE IS IN USE, DO NOT LOOK DIRECTLY INTO THE LASER BEAM–PERMANENT EYE DAMAGE MAY
RESULT.
2. USE EXTREME CAUTION WHEN OPERATING THE LASER.
3. NEVER POINT THE DEVICE TOWARDS ANYONE’S EYES.
4. KEEP OUT OF REACH OF ALL CHILDRENSTORAGE & CLEANINGIt should be stored at room temperature. The sensor lens is the most delicate part of the thermometer. The lens should be kept
clean at all times, care should be taken when cleaning the lens using only a soft cloth or cotton swab with water or medical
alcohol, allowing the lens to fully dry before using the thermometer. Do not submerge any part of the thermometer.
LCD ERROR MESSAGESThe thermometer incorporates visual diagnostic messages as follows:‘Hi’ or ’Lo’ is displayed when the temperature being measured is outside of the settings of HAL and LAL.
‘Er2’ is displayed when the thermometer is exposed to rapid changes in the ambient temperature. ‘Er3’ is displayedwhen the ambient temperature exceeds 0℃ (32°F) or +50℃ (122°F). The thermometer should be allowed plenty oftime (minimum 30 minutes) to stabilize to the working/room temperature.
Error 5~9, for all other error messages it is necessary to reset the thermometer. To reset it, turn the instrument off,
remove the battery and wait for a minimum of one minute, reinsert the battery and turn on. If the error message
remains, please contact the Service Department for further assistanceBATTERIESThe thermometer incorporates visual low battery indication as follows:‘BatteryOK’:measurements

are possible‘Battery Low’: battery needs to be replaced,‘Battery Exhausted’:measurements are still possible

measurements are not possible

BATTERY REPLACEMENT
1. Pull out the rubber gasket (10)
2. Loosen the screw and pull out the battery cover
3. Replace and reinstall with new batteries
4. Place the battery cover back and fasten the screw
5. Plug the rubber gasket (10) to avoid failure of water proof
When the ‘Low Battery’ icon indicates the battery is low, the battery should be replaced immediately with AAA, 1.5V batteries.
Please note: It is important to turn the instrument off before replacing the battery otherwise the thermometer may malfunction
Dispose of used battery promptly and keep away from children.
