(larger) readout and the maximum, minimum or average measurement, or the largest difference between measurements, during that session on a secondary (smaller) readout. The OS730K, the “K” type bead thermocouple, a “9V” battery and this user’s manual are packaged in a soft pouch inside a box. -

SAFETY INSTRUCTIONS CAUTION! The OS730K is a Class 2 laser product that emits less than 1mW of radiation at a wavelength between 630 and 670nm. 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. -

WHAT’S IN THE PACKAGE The OS730K comes in a soft pouch inside a box along with a “K” type bead thermocouple probe, a “9V” battery and this user’s manual. PRODUCT OVERVIEW Fig. 1 shows all controls, indicators, connectors and other physical features of the OS730K. -
Page 7: Setup Instructions
SETUP INSTRUCTIONS INSTALL BATTERY The OS730K’s battery compartment (Fig. 1, Callout 4) is below the measurement trigger and accessible from the front of the grip. Before installing the “9V” battery included in the package, remove the plastic wrap covering its terminals. -
Page 8: Operating Instructions
OPERATING INSTRUCTIONS USING THE IRT TO MEASURE TEMPERATURE This section describes how to operate the OS730K in its “normal” mode, with and without use of the backlight and/or laser pointer. In this mode (called REC mode), each measurement made by squeezing the measurement trigger is automatically stored (recorded) in a numerically tagged location in the instrument’s nonvolatile memory. -

SCAN mode. CHOOSING AN IRT DISPLAY MODE Because the OS730K automatically records and tags every measurement it makes, it can analyze the set of readings made and stored over any finite period of time. Often, the period that provides the most useful information is the measurement session—the time during which... -

0.10 and 1.00 in steps of 0.01. The default (factory setting) of ε is 0.95. Because the OS730K measures the amount of infrared energy emitted by a surface, its measurements are most accurate when they take into account the characteristic emissivity of the target material. -

HAL setpoint. The Low Temperature Alarm is activated when the temperature measured by the IRT is lower than the LAL setpoint. In each case, the OS730K responds by sounding a second chirp (following the usual first chirp to indicate that a measurement was made and stored) and flashing an icon on the bottom line of the LCD (Fig. -

(or another “K” type probe): 1) Plug the two prongs of the probe into the two slots on the bottom of the OS730K. Be sure to insert the slightly narrower (+) prong into the slightly narrower slot, which is closer to the rear of the unit. -

D:S ratio of 30:1 enables narrow measurement of high-temperature objects (up to 1472ºF/800ºC) from a safe distance. To eliminate measurement error, move the OS730K close enough to the target so the circle created by the targeting laser falls just within the object being measured. See Appendix II for a brief tutorial: How to Make Accurate IR Temperature Measurements. - Page 14 -58°F (-50°C)—the lower limit of the measurement range—“OL” will appear on the main readout. The OS730K cannot make accurate measurements if there is glass or plastic between it and the target. Clean the lens of the infrared sensor lens (Fig. 1, Callout 2) often—but never use a solvent.
- Page 15 The OS730K’s field of view HOW TO MAKE ACCURATE IR MEASUREMENTS The OS730K has a distance-to-spot (D:S) ratio of 30:1. This means that the target area (spot) whose infrared radiation (temperature) is being measured increases in diameter by 1 inch for every 30 inches you move away from the target. Conversely, the diameter of the target area measured decreases by 1 inch for every 30 inches you move closer to the target.
- Page 16 Tavg = (Tmotor + Tbackground) ÷ 2 Solving for Tavg, we get (200 + 75) ÷ 2 or 137.5°F., which is what the OS730K would display. In other words, trying to measure the temperature of the motor from 60 ft.
