The PosiTector Infrared Thermometer (IRT) is a hand-held, electronic instrument that measures surface temperature quickly and accurately. It consists of a body (Standard or Advanced) and a probe (pg. 2).
This Quick Guide simmarizes the basic functions of the Gage.
The PosiTector IRT powers-up when the center navigation button is pressed. Readings are updated automatically each second. To preserve battery life, the instrument powers down after approximately 5 minutes of no activity. All settings are retained.
- Remove the protective rubber cap form the probe.
- Power-up Gage by pressing the center navigation button.
The infrared temperature sensor immediately begins measuring. Press the (+) button to pause the measurement. Press (+) again to resume.
Button Functions - Normal Operation
Press and hold the Down button to activate the laser pointer. The laser helps aim the ifrared temperature sensor. Release the button to deactivate the laser. The symbol is displayed on the screen when the laser is active.
Laser Radiation. Do not stare into beam. Class 2 laser product.
Gage functions are menu controlled. To access the Menu, power-up the Gage, then press the center navigation button.
To navigate, use the Up and Down buttons to scroll vertically and to SELECT
Press the (+) button to switch pages in a mulipage menu.
Press the (-) button to return to the previous menu or page.
Select Exit to exit from any menu.
When powered-up, the PosiTector automatically determines which probe is attached and does a self-check.
To disconnect a probe form a body, slide the plastic probe connector horizontally (in the direction of the arrow) away from the body. Reverse these steps to attach a different probe. It is not necessary to power-down the Gage when switching probes.
The PosiTector gage body accepts a wide variety of probe types including magnetic, eddy current and ultrasonic coating thickness, environmental, surface profile, shore hardness durometer, salt contamination and ultrasonic wall thickness probes. See defelsko.com/probes.
Emissivity refers to a material's ability to emit infrared energy, compared to an ideal black surface at the same temperature. The ratio varies from 0 to 1, and each material has a specific emissivity associated with it. The
Most organic and painted surfaces have an emissivity of around 0.95, and are ideal surfaces for accurate infrared temperature readings. Shiny or reflective surfaces can be difficult to measure with an infrared thermometer, as they tend to reflect ambient infrared energy instead of their own. To compensate for this, cover such surfaces with flat paint or a piece of electrical tape. Allow the paint or tape to acclimate to the surface's temperature, and take a measurement over the paint or tape.
The distance to spot ratio refers to the relationship between the diameter of the area being measured compared to the instrument's distance from the area. As the distance (D) from the target increases, the spot size (S) of the area being measured by the unit becomes larger. The D:S ratio of the PosiTector IRT is 5.7:1. For example, when the instrument is 100 cm (40 inches) from the target, the spot size will be about 18 cm (7 inches) in diameter.
Converts the displayed units for temperature. Celsius (°C) or Fahrenheit (°F)
Reset (menu reset) restores factory settings and returns the Gage to a known condition. The following occurs:
- All batches and stored readings, batch names and screen captures are erased.
Menu settings are returned to the following:
Memory = OFF Auto Dim = ON Statistics = OFF Bluetooth & Stream = OFF HiLo Alarm = OFF WiFi & Access Point = OFF Trend Chart = None Display = None
Perform a more thorough Hard Reset as follows:
- Power down the Gage and wait 5 seconds.
- Simultaneously press and hold the (+) and center buttons until the Reset symbol appears.
This returns the Gage to a known, "out-of-box" condition.
It performs the same function as a menu Reset with the addition of:
- Bluetooth pairing info is cleared.
- Alarm settings are set to defaults.
Menu settings are returned to the following:
Units = Celsius Emissivity = 0.95 Flip Lock = OFF Battery Type = Alkaline Auto Sync.net = ON Backlight = Normal Sound = ON Bluetooth Smart = OFF Language = English USB Drive = ON
Date, Time and WiFi settings are not affected by either Reset.
Displays information on the gage body and attached probe.
Turns the trend chart on. The trend chart can also be turned on by pressing the Up navigation button from the main screen.
Sets the emissivity ratio for the PosiTector IRT infrared temperature sensor.
Select Custom to manually adjust the emissivity value or to adjust to a known temperature. Emissivity is automatically calculated when adjusting to a temperature. See NOTE below.
Alternatively, use one of the following preset options:
|Aluminum (rough) = 0.07||Plastics = 0.94|
|Zinc (Galvanized) = 0.25||Steel (Oxidized) = 0.95|
|Concrete = 0.54||Wood = 0.95|
|Paint = 0.96|
Depending on surface treatment, metals such as blasted steel can have a broad range of emissivity balues. Adjusting to a known temperature (measured by a direct contact surface temperature probe) on a representative sample will assist in obtaining an accurate emissivity value.
Select to disable the auto rotate feature.
Selects the type of batteries used in the Gage from a choice of "Alkaline", "Lithium" or "NiMH" (Nickel-metal hydride rechargeable). If NiMH is selected, the gage will trickle charge the batteries while connected via USB to a PC or optional AC charger. The battery state indicator icon is calibrated for the selected battery type. No damage will occur if the wrong battery type is selected.
A statistical summary will appear on the display. Reset statistics by pressing the (-) button. Press (+) to pause statistics.
Allows Gage to visibly and audibly alert the user when readings exceed user-specified limits.
The PosiTector IRT has internal memory storage for recording measurement data. Stored readings can be reviewed on-screen or accessed via computers, tablets and smartphones. Each reading is date and time-stamped. Press the (+) button to store a measurement.
The symbol appears when the Gage is set to store readings.
Standard models store up to 250 readings in one batch.
Advanced models store 100,000 readings in up to 1,000 batches. "New Batch" closes any open batch and creates a new batch name using the lowest available number. New batch names are date stamped when they are created.
Press both (-)(+) buttons at any time to capture and save an image copy of the current display. The last 10 screen captures are stored in memory and can be accessed when connected to a computer.
