SPECIFICATIONS 
Range: 
–76° to 932°F / –60° to 500°C
Resolution:
0.1° (–9.9° to 199.9°) 1° (otherwise)
 
OPERATION 
Press and continue to hold down the trigger to take temperature readings. The 
unit will take temperature readings while the trigger is pressed and held (SCAN 
appearing on the display indicates measurements are being taken). 
After the trigger is released, the last temperature measured will be displayed for 
approximately 60 seconds, the display will then turn off automatically. HOLD will 
appear on the display when the trigger has been released to indicate that the 
unit is no longer taking temperature measurements. 
 
SELECTING UNITS OF MEASURE 
Press and release the trigger to turn on the display. Once the display is on (and 
the trigger has been released), each press of the °C/°F button will toggle 
between °C and °F. (If the trigger is being held when the °C/°F button is 
pressed, this will laser targeting on/off.) 
 
LASER TARGETING 
While pressing and holding the trigger, each press the °C/°F button toggles 
laser targeting on and off. With laser targeting on, each time the trigger is 
pressed and held, the laser beam will be emitted. 
 
CAUTION: Eye damage may result from direct exposure to laser light. 
 
DISTANCE SPOT/RATIO 
There are other factors that may affect measurement accuracy. The target must 
completely fill the spot diameter seen by the infrared sensor; otherwise readings 
will be influenced by the surface surrounding the target. The ratio of the distance 
to the size of the spot being measured is 11:1. For example, an object’s 
diameter of 100mm can be measured from 1100mm. 
 
BACKLIGHT 
While pressing and holding the trigger, each press the LOCK button toggles the 
LCD backlight on and off. With the backlight on, each time the trigger is pressed 
and held, the LCD will be illuminated by the backlight. 
 
VALUES RECORDED 
With each press of the trigger, five values are recorded: 
1. MAX – Highest temperature measured. 
2. MIN – Lowest temperature measured. 
3. dIF – Difference between MAX and MIN. 
4. AVG – Time-weighted average temperature. 
5. The value last displayed before releasing the trigger. (Appears at the bottom 
of the display.) 
 
DISPLAY MODES 
Each press of the MODE button will select one of the 8 display modes. You can 
cycle through the modes in this order: 
“E” – Emissivity value display (See the Emissivity section).
“MAX” (Maximum temperature) – Press the MODE button until MAX appears 
on the display. In the MAX mode, the highest temperature measurement taken 
is displayed to the right of MAX. This value will update each time a higher 
temperature is measured.
“MIN” (Minimum temperature) - Press the MODE button until MIN appears 
on the display. In MIN mode, the lowest temperature measurement taken is 
displayed to the right of MIN. This value will update each time a new lower 
temperature is measured. 
“dIF” (Temperature differential between MAX and MIN) – Press the MODE 
button until dIF appears on the display. The difference between the MAX and 
MIN reading is displayed to the right of dIF. This value is updated as new MAX 
and MIN temperatures are measured.
“AVG” (Calculated (time weighted) average temperature] – Press the MODE 
button until AVG appears on the display. The time weighted average 
temperature reading is displayed to the right of AVG. This value is updated 
continuously while the trigger is being pressed.
The term “time”, in reference to the averaging mode, means all temperature 
measurements are averaged together from the first press of the trigger. 
TRACEABLE® INFRARED THERMOMETER WITH TRIGGER GRIP INSTRUCTIONS
Example: If the temperature was 72° for one minute, then 20° for ½ second, no 
significant change in average temperature would be displayed. 
“HAL” (High Temperature Alarm) – Press the MODE button until HAL
appears on the display. The high temperature alarm value that has been set is 
displayed to the left of HAL. (See High/Low Alarms section.) 
“LAL” (Low Temperature Alarm) – Press the MODE button until LAL
appears on the display. The low temperature alarm value that has been set is 
displayed to the left of LAL. (See High/Low Alarms section.) 
“PRB” (Probe Temperature) – Press the MODE button until PRB appears 
on the display. The external probe temperature is displayed to the left of PRB. 
If no probe is connected, noP will appear to the right of PRB. 
 
With a probe connected, the unit will display the probe temperature without 
pressing the trigger. While in PRB mode, the unit will turn off automatically after 
12 minutes if no buttons are pressed. Only Type-K thermocouple probes may 
be used with this unit. 
 
NOTE: The last mode selected will remain selected the next time the trigger is 
pressed. 
 
MEMORY RECALL 
With each press of the trigger, five values are recorded: 
1. 
MAX – Highest temperature measured.
2.
MIN – Lowest temperature measured.
3.
dIF – Difference between MAX and MIN.
4.
AVG – Time-weighted average temperature.
5.
The value last displayed before releasing the trigger.
 
To cycle through each of the values recorded during the last measurement, 
press the MODE button. (See the “Display Modes” section for an explanation of 
the values displayed.) 
 
HI/LOW Alarms 
An audible alarm will sound at both an upper and a lower temperature limit. To 
adjust the alarm temperature set points: 
1. Press the MODE button until “HAL” (High Temperature Alarm) or 
“LAL” (Low Temperature Alarm) is displayed.
2. To adjust the temperature alarm set point, press the ↑ or ↓ button. (Do not
press the trigger while adjusting the alarm set points). Press and hold to
advance the display rapidly.
3. Once the desired temperature alarm set point appears on the display, press
the trigger to confirm the value.
 
While taking temperature measurements, an alarm will sound when the 
temperature measured is above or below High and Low alarm set points that 
have been entered. If the temperature is above the High Alarm set point, (((HI))) 
will appear at the top right corner of the display. If the temperature is below the 
Low Alarm set point, (((LO))) will appear at the top right corner of the display. 
 
The alarm will sound regardless of the Display Mode if the temperature 
measured is above or below High and Low alarm set points that have been 
entered. 
 
LOCK FUNCTION 
The lock function allows the thermometer to take measurements without having 
to press and hold the trigger. When the lock function is activated, the unit will 
take continuous temperature measurements for 60 minutes and will then turn off 
automatically to preserve battery life. 
 
To activate the lock mode, while in the E, MAX, MIN, dIF, or AVG mode, 
press the LOCK button. LOCK and SCAN will appear on the display to indicate 
that the unit is in the lock mode and is taking measurements. (Do not press and 
hold the trigger while activating the lock mode.) 
 
To deactivate the lock mode, while in the E, MAX, MIN, dIF, or AVG 
mode, press the LOCK button. HOLD will appear on the display to indicate 
that the unit is no longer taking measurements. (Do not press and hold the 
trigger while deactivating the lock mode.)
