ebro TFI-54 Infrared Thermometer
Operating Instructions
The thermometer is a non-contact infrared thermometer. There are many mathematical modes for the Infrared function. Please remember to keep away from children and don‟t use it for safety-related applications
Simply aim the thermometer at the measure target with Lens (9) and press Meas. key (7) to display the surface temperature. The Distance:Spot is 12:1. Please make sure the target area is within the field of view.
OVERVIEW
FUNCTION
- Here will show the emissivity data. (The default emissivity is 0.95.)
- Press Mode key (2) , then press Lock key (4) or oC/ 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 Maximum (MAX), Minimum (MIN), die Difference between MAX and MIN (DIF) and Average (AVG) modes. During measurement, the special modes reading will be displayed beside the mode icon
- Press Lock key (4) oder oC/ oF key (3) to change the High Alarm (HAL) or Lo Alarm (LAL) , then press Meas. key (7) to confirm it. When the reading is outside the High Alarm (HAL) or Lo Alarm (LAL) limit, the High or Low icon will flash and you will hear a beep sound.
Add Value
In E,MAX, MIN, DIF, AVG
mode:
| Press Lock key (4) for LOCK mode ON/OFF. The lock mode is particularly useful for continuous monitoring of temperatures for up to 60 minutes.
Press o C/ oF key (3) for o C or oF transferred.
---|---
In all modes: First hold on the Meas. key (○,7)| and press Lock key (4) for
backlight function ON/OFF.
and press oC/ oF key (3) for laser function ON/OFF.
Memory| Recall the last memory by pressing Mode key (2) while power off
CAUTION
- WHEN THE DEVICE IS IN USE, DO NOT LOOK DIRECTLY INTO THE LASER BEA PERMANENT EYE DAMAGE MAY RESULT.
- USE EXTREME CAUTION WHEN OPERATING THE
- NEVER POINT THE DEVICE TOWARDS ANYONE‘S |
- KEEP OUT OF REACH OF ALL
STORAGE & CLEANING
It 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 MESSAGES
The thermometer incorporates visual diagnostic messages as follows:
- ‘Hi‘ or‘Lo‘ is displayed when the temperature being measured is outside the settings of HAL and LAL
- ‘Er2‘ is displayed when the thermometer is exposed to rapid changes in the ambient temperature. ‘Er3‘ is displayed when the ambient temperature exceeds 0°C (32°F) or +50°C (122°F). The thermometer should be allowed plenty of time (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 instrumet 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 assistance
Batteries
The thermometer incorporates visual low battery indication as follows
Battery Replacement
- Pull out the rubber gasket (10)
- Loosen the screw and pull out the battery cover
- Replace and reinstall with new batteries
- Place the battery cover back and fasten the screw
- Plug the rubber gasket (10) to avoid failure of water proof
Warning
- 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.
