User Guide InfraRed (IR) Thermometer with Wireless Datalogger, Type K input & Laser Pointer MODEL 42560
Introduction Congratulations on your purchase of the Model 42560 IR Thermometer. The Model 42560 IR thermometer measures and displays non-contact (infrared) surface temperature to a maximum of o o 1922 F (1050 C). The built-in laser pointer increases target accuracy while the backlit LCD and handy push-buttons combine for convenient, ergonomic operation. The Type K thermocouple o o input provides contact measurements up to 2498 F (1370 C)*.

Operating Instructions Power 1. The meter is powered by one (1) 9V battery. 2. The transmitter base can also be powered by the 9V battery in the meter or by the supplied AC adaptor. IR (non-contact) Measurements 1. Hold the meter by its handle and point it toward the surface to be measured. 2. Pull and hold the trigger to turn the meter on and begin testing. The temperature reading, the flashing ‘SCAN’ icon, the emissivity, the unit of measure and other icons as shown in the Display Description will appear.
The MODE button options The MODE button is used to select from a list of available meter functions. The selected function is displayed on the bottom line of the LCD. Each function is listed below along with a detailed account of its use. Press the MODE button to step from one function to the next. EMS (Emissivity Value) To change the emissivity value, use the UP and DOWN arrows (the available emissivity range is 0.10 to 1.00). The current emissivity setting is always shown at the top of the LCD display.
IR Measurement Notes 1. The object under test should be larger than the spot (target) size calculated by the field of view diagram (printed on the side of the meter and in this guide). 2. Before measuring, be sure to clean surfaces that are covered with frost, oil, grime, etc. 3. If an object's surface is highly reflective, apply masking tape or flat black paint to the surface before measuring. Allow time for the paint or tape to adjust to the temperature of the surface it is covering. 4.
Emissivity and IR Measurement Theory IR Thermometers measure the surface temperature of an object. The thermometer’s optics sense emitted, reflected, and transmitted energy. The thermometer’s electronics translate the information into a temperature reading which is then displayed on the LCD. The amount of IR energy emitted by an object is proportional to an object's temperature and its ability to emit energy.
Datalogging Wireless Datalogging The Model 42560 is supplied with a Wireless Datalogging system for use with a PC. The kit contains software (CD-ROM), Transmitter base, and a USB Data Receiver. Readings can be automatically transferred from the IR thermometer to a PC using the wireless datalogging system for distances up to 100 ft. (30m). Instructions for use are provided in the HELP menu of the supplied software program. The Main software screen is reproduced below for preview & reference.
Analog Output The Model 42560 is supplied with a banana plug pair to 3.5mm mini-plug cable. The mini-plug end of the cable connects to the meter’s Transmitter base. The banana plug test lead end can be connected to an external device such as a MultiMeter, chart recorder, magnetic tape storage device, etc. to collect readings. An analog output of 1mVDC per degree F is provided from the output jack of the transmitter base. Internal Datalogging The 42560 has a 20-reading internal memory.

Battery Replacement When the low battery symbol appears on the LCD, replace the meter’s battery (9V). The battery compartment is located behind the panel that surrounds the meter’s trigger (see diagram). Open the compartment by carefully pulling the panel down away from the trigger area. The panel is hinged at the bottom and does not completely disconnect from the meter. Replace the 9V battery and close the battery compartment cover.
