The IRT659K can measure surface temperature using either of two methods: non-contact (using an IR thermometer with a laser pointer) or contact (using a “K” type thermocouple). A “K” type thermocouple with a wide measurement range is included in the package. The instrument automatically stores its last 10 IR readings in a nonvolatile memory for later recall in reverse chronological order.
SAFETY INSTRUCTIONS CAUTION - Use of controls or adjustments or performance of procedures other than those specified herein may result in dangerous radiation exposure. The IRT659K is a Class 3R laser product that emits less than 3mW of radiation at a wavelength of 655nm. Avoid looking directly at the laser pointer. U.S. law prohibits pointing a laser beam at aircraft; doing so is punishable by a fine of up to $10,000 and imprisonment. The laser may cause discomfort if viewed directly.
PRODUCT OVERVIEW Fig. 1 shows all controls, indicators, connectors and other physical features of the IRT659K. Fig. 2 shows all possible indications on the unit’s LCD. Familiarize yourself with the positions of all controls and connectors and the meaning of all display indications and icons before moving on to the Setup Instructions and Operating Instructions.

SETUP INSTRUCTIONS INSTALL BATTERY The IRT659K’s battery compartment (Fig. 1, Callout D) is below the measurement trigger and accessible from the front of the grip. Before installing the “9V” battery included in the blister pack, remove the plastic covering its terminals. To install the battery: 1. Open the battery compartment by placing your thumb and forefinger in the indentations on the sides of the grip and pulling the top of the compartment forward. 2.
on the bottom line. Also note that this second reading will be accompanied by the tag 02 to the right of the word LOG. 4. Squeeze and hold the trigger again and then release it. Allow 30 seconds to pass. Note that after 30 seconds the unit’s Auto Power Off function will activate and cause the unit to shut down silently. To change the measurement unit from the default °F to °C, press the °F/°C 쒆 button (Fig. 1, Callout H). To return to Fahrenheit measurement, press the button again.
By default, the unit enters MAX display mode when powered on. To change the display mode, you use the MODE/SET button to cycle through a seven-step sequence comprising the four display modes plus three settable parameters, as shown in the following figure. To move from one display mode to the next mode in the sequence, briefly press (but do not hold) the MODE/SET button. As mentioned earlier, you can change the display mode before or during a scanning session.
2. High Temperature Alarm (HAL). HAL can be set to any integral temperature value from -58° to 1202°F (-50° to 650°C)—the operating range of the IRT659K. The default (factory preset value) is 1210°F (650°C)—the highest temperature that the unit can measure. 3. Low Temperature Alarm (LAL). LAL can also be set to any integral temperature value from -58° to 1202°F (-50° to 650°C). The default (factory preset value) is -58°F (-50°C)—the lowest temperature that the unit can measure.
Pressing the MODE/SET button with HAL flashing returns the three-step sequence to its starting point—with ε flashing. The figure right shows the sequence in graphic form. Be aware that, unlike the main readout and the display mode temperature values MAX, MIN, AVG and DIF (all of which have 0.1° resolution), LAL and HAL only have 1° resolution. In other words, do not mistake the default HAL value of 1210°F for 121.0°F.
2) Press the IR/K (TC) button (Fig. 1, Callout I). Note that this causes the IRT LOG information on the bottom line of the LCD to disappear and disables the MODE/SET and 쒅 LOG buttons. 3) Attach the end of the probe to the surface whose temperature you wish to measure. The measured value will appear on the main readout. If you allow the IRT659K’s 30-second Auto Power Off function to activate with the unit in thermocouple measurement mode, when you power the unit back on it will enter IRT measurement mode.
Dimensions Weight Power Source 5.31 x 1.65 x 6.81 in. (135 x 42 x 173mm) 6.93 oz. (168g) (without battery) (1) “9V” battery (included) OPERATING & MAINTENANCE TIPS If the temperature of the IRT’s target is lower than -58°F (-50°C)—the lower limit of the unit’s measurement range—“OL” will appear on the main readout. If the temperature of the IRT’s target is higher than 1202°F (650°C)—the upper limit of the unit’s measurement range—“OH” will appear on the main readout.
