ThermoWorks R-PRO PROFESSIONAL INFRARED THERMOMETER - Manual

Professional Infrared Thermometer (with type K socket) – The thermometer is a non-contact
infrared thermometer. 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 ≥ and press Meas. key ≈ to display the surface temperature. The Distance:Spot is
50:1. The two laser points are the reference for the target spot size. Please make sure the target area is within the field of view.

FUNCTION
Press Emissivity key  for setting the emissivity
Press Emissivity key , then press Up key  or Down key  to set the emissivity, then press Mode key  to confirm it. The emissivity can
be changed from 0.10 (10E) to 1 (100E).
Press Mode key  for scrolling more display function as follows.
Here will show the emissivity data. (The default emissivity is 0.95.)
Press Mode key  for the Maximum (MAX), Minimum (MIN), Different between MAX and MIN (DIF) and Average (AVG)
modes. During the measurement, the special modes reading will be displayed beside the mode icon.
Press Up key  or Down key  key to change the High Alarm (HAL) or Lo Alarm (LAL), then press Meas. key ≈ to confirm it.
For example: When the reading 26.9°C < LAL 27°C, the Low icon will flash and you will hear a beep sound.
Connect the thermocouple with Thermocouple socket and put the probe in/on the target, the thermometer will display the temperature
automatically without pressing any button. To see the minimum or maximum data during the probe measurement, please hold down the Up key

or Down key .
After measuring high temperatures, the probe may remain HOT for a while.
** The thermometer will automatically shut off if left idle for more than 60sec.
In MAX, MIN, DIF, AVG mode: Press Up key  for LOCK mode ON/OFF. The lock mode is particularly useful for continuous monitoring of
temperatures for up to 60 minutes.
Press Down key  to change display units from °C to °F and back
In all modes: First hold on the
Meas. key ≈
and press Up key  for backlight function ON/OFF.
and press Down key  for laser function ON/OFF.
CAUTION
1. WHEN DEVICE IS IN USE, DO NOT LOOK DIRECTLY INTO THE TWO LASER BEAMS–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 & CLEANING The thermometer should be stored at room temperature between –20 to +65°C (-4~149°F). 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
LOW
‘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 displayed when the
ambient temperature exceeds 0oC (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, wait for auto power 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 ThermWorks for further assistance.
‘Hi’ or ’Lo’ is displayed when the temperature being measured is outside of the measurement range.
BATTERIES
The thermometer incorporates visual low battery indication as follows:
‘Battery OK’: measurements are possible ‘Battery Low’: battery needs to be replaced,
measurements are still possible
‘Battery Exhausted’: measurements are not possible
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.
