Thermometer
INTRODUCTION
This manual describes the basic function, use and safety instructions for the
model TL3-A, TL3-W and TL3-R portable
digital reference thermometer instruments.
REPLACING BATTERY
When the battery voltage is low, the display will show ‘Lo bAtt”‘.
Replace the battery as soon as possible in a safe location after the low
battery is noticed. This will avoid possible
malfunctioning. Do not attempt to calibrate the instrument if the low battery
indicator is displayed.
WARNING:
- Batteries must be changed in Non-hazardous area.
- Batteries must be of correct approved type.
- Batteries must be installed with correct polarity making sure the (+) end of the battery is aligned with (+)
- symbol embossed in the battery case.
- Batteries must not be installed with polarity reversed where one cell could charge another cell.
- Ensure the instrument is in a non-hazardous area & powered off.
- Use a #2 Phillips drive to remove the 1 screw holding the back cover on the TL3.
- Replace each new battery making sure the (+) end of the battery is aligned with (+) symbol embossed in the battery case.
- Reinstall the cover. Make sure the rubber gasket is seated in its groove around the case opening (TL3-W, TL3-R). CERTIFIED
Batteries for the TL3-A, TL3-W and TL3-R are as follows:

AUTHORIZED REPAIR
It is recommended that service beyond the scope of this manual be performed by
ThermoProbe, Inc. or one of its authorized distributors.
See www.thermoprobe.net for video on proper use
of this instrument.
USER INTERFACE
Power/Select Button:
Pressing the Power button once will turn on the device. (Note: The instrument
will automatically power off 20 minutes after the last button push.) Pressing
and holding the “Power” button until it displays “OFF will turn off the
instrument.
Selection MENU
Use the Advance (down arrow) button for the following selections:
- C-F: Select Celsius or Fahrenheit temperature display
- DEC: Select 0.1 or 0.01 display resolution (0.01/0.001 for TL3-R
- LAH-Displays Lowest reading (LO), Average reading (AVG) and Highest reading (HI)
- CON: Switches between auto of or continuous operaion
- STRT BT/STOP BT: Start or Stop Bluetooth (TL3-W or TL3-R)
- ZERO: Allows user to view or adjust the zero correction
- TL3-R model only – See Zero Correction section)
Lowest, Highest & Average readings
The lowest, highest and average temperatures recorded while the TL3 is powered
on can be accessed from the menu.
These are indicated by LO, AVG or HI indicators shown on the display
immediately before the corresponding reading is displayed. These readings are
deleted after the unit is powered off Bluetooth Wireless (7TL3-W or TL3-R
models only) Bluetooth can be enabled from the menu to transmit temperature
data to supported Bluetooth devices. Please go to
www.thermoprobe.net for additional information
and drivers.
Display Codes
- OPEN Ct – Indicates the sensor is operating above its temperature limit, or the sensor is damaged.
- Shrt Ct- Indicates the sensor is operating below its temperature limit or the sensor is damaged.
- Lo bAtt- Indicates the battery voltage is low.
Zero Correction (TL3-R model only)
Note : A password (247) is required to enter Zero Correction mode.
Correetions made will offset temperature over the entire range of the device.
Zero correction should only be performed by qualified personnel with proper
reference instrumentation. Zero Correction is intended to be performed at
water freezing point 0°C (32°F).
The Zero Correction can be accessed by selecting ZErO from the menu. From the
Zero Correction menu, selecting Corr will display the current zero
correction.
Selecting Add will display a password field of 3 digits. Enter the password
(247) one digıt at a time using the ADVANCE button to increment each display
digit. Then use the SELECT button to go to the next digit. Pressing
SELECT for the 3″ digit will take you to a temperature display where you can
adjust the displayed temperature. The arrow indicator shows the direction you
are changing the temperature. Press and hold the ADVANCE button to
increment the value by 0.001 degrees until it reaches 10 and then it will
increment at a rate of0.01 degree per second. Use the SELECT button to go from
adjust UP, adjust DOWN, SAvE correction, and CAnCEL (don’t save).
Once you have saved the adjustment you can view the zero adjustment being
applied from the ZErO>Corr>Displays current correction’ menu selection.
SAFETY INSTRUCTIONS- TL3-A, TL3-W & TL3-R
REV 042020
These ThermoProbe instruments are intended for use in both hazardous
(potentially flammable or explosive) and non hazardous areas under dry
conditions at ambient temperatures between-20°C to 40°C. The instruments are
not intended for use in permanent outdoor installations and are not intended
or tested for icing conditions. Additional means of protection should be used
where the equipment may be exposed to excessive external stresses (e.g.
vibration, heat, impact, etc.). The user must have a working knowledge of
appropriate safety requirements. Be aware of aggressive substances and that
extra protection may be needed. Exposure to excessive heat can melt the
plastic components of the instrument.
-
The user must have a thorough knowledge of the products to be measured and must know of the safety precautions to be taken when working with the material to be measured.
-
The instrument shall be checked concerning severe defects; check that instrument is complete, has good batteries, etc. If necessary, check measurement accuracy. If any defects are found, the instrument should not be used until
repairs have been made. -
The instrument should be clean for safety and ease of use.
-
The physical measurement location should be evaluated for primary and secondary risks.
-
Power source must be removed before performing any maintenance.
-
Exchange of components other than the batteries may compromise ATEX/IECEx or other certifications and shall only be undertaken by ThermoProbe or one of its qualified service providers. See also “Authorized Repair” section.
CAUTION
The following metal parts have a capacitance in excess of 3pF, are isolated
from ground and may pose a potential electrostatic charging hazard: (Metal
probe – 19.5pF)
In the event that any part of the instrument should become electrostatically
charged in a potentially
hazardous location, follow company policies for testing and clearing the area
of any hazardous gases before attempting to use the instrument in that
location. If this is not possible allow sufficient time for the instrument to
naturally dissipate any charges. Given the atmosphere, this could take several
hours.
SAFETY APPROVALS FOR TL3-4, TL3-W AND TL3-R:
Applicable Standards are:
- IEC 60079-0:Ed 7, IEC 60079-11:Ed 6
- EN 60079-0:2018, EN60079-11:2012
Agency or Safety Designation
- TECEx: Internationally Recognized Body
- ATEX: Europe
INTRINSIC SAFETY
Intrinsically safe equipment is defined as “equipment and wiring which is
incapable of releasing sufficient electrical or thermal energy under normal or
abnormal conditions to cause ignition of a specific hazardous atmospheric
mixture in its most easily ignited concentration.” (ISA-RP12.6) This is
achieved by limiting the amount of power available to the electrical equipment
in the hazardous area to a level below that which will ignite the gases.
In order to have a fire or explosion, fuel, oxygen and a source of ignition
must be present. An intrinsically safe system assumes the fuel and oxygen are
present in the atmosphere, but the system is designed so the electrical energy
or
thermal energy of a particular instrument loop can never be great enough to
cause ignition.
BATTERIES
- Batteries must be changed in Non-hazardous area.
- Batteries must be of correct approved type.
- Batteries must not be mixed with batteries of other models or manufacturers.
- Batteries must be installed with correct polarity making sure the (+) end of the battery is aligned with (+) symbol embossed in the battery case.
CERTIFIED Batteries for the TL3-A, TL3-R and TL3-W are as follows
