Safety

International Safety Symbols
This symbol, adjacent to another symbol or terminal indicates the user must refer to the manual for further information

Warnings

• Do not directly or indirectly point the laser at the eyes of a person or an animal aspect for damage or for any shortage of parts or accessories before use
• Replace the batteries immediately after the battery indicator flashes o Do not use the thermometer near explosive gases, steam, or dust
• Note that an object with high reflectivity will normally cause the measured temperature value to read much lower than the actual temperature
• Use the device only as described in this User Guide

Cautions

• To avoid thermometer damage, please avoid the following hazards: EMF from welding equipment or electro‐ induction heaters o Static electricity
• The thermal shock is caused by large or abrupt environmental temperature changes; wait 30 minutes to allow the thermometer to stabilize to new environmental conditions
• Do not use this device in excessively high-temperature environments

Operation

Meter Power
The meter is powered by two 1.5V AA batteries. With fresh batteries installed, the meter switches ON when the trigger is pulled. Refer to the Maintenance section for Battery  Installation instructions. The battery icon provides a battery status indication. Replace the batteries as soon as the battery status icon indicates a low battery.

Setting Mode
The various parameters of the meter are set using the five‐way multi‐switch located below the display. The available parameters are listed below:

Setting Mode Overview
The Settings switch has five positions to select a parameter, turn a parameter ON or OFF, and to adjust parameter values.
Press and release the Measurement Trigger.
Press the button left to enter the Setting Mode. The parameter selected will appear in the display.
Press the button right to advance to the next parameter.
Press the up or down buttons to change a parameter status or adjust a parameter value.
Press the button to store parameter changes and advance to the next parameter.
Press the button left to exit the Settings mode and return to Measurement mode.

Note: If no button is pressed within the APO time the meter will shut down. It may be helpful to extend the APO time when making adjustments in the Settings mode.

Surface Temperature Measurements

1. The typical settings should be: Laser pointer ON, Backlight ON, Temperature units set as needed, Emissivity set to 0.95, APO (auto power OFF) set to 10 seconds, and Flashlight ON if measuring in a dimly lit area.
2. Open the lens protective lens cover by rotating the cover wheel clockwise (facing the lens) until the dot is visible on the wheel.
3. Hold the meter by its Handle Grip and point it toward the surface to be measured.
4. Pull and hold the Trigger to turn the meter on and begin testing in Scan mode. The display will light if the batteries are good. Replace the batteries if the display does not light.
5. Release the Trigger; the reading will HOLD for the time set in the APO setting. The backlight will turn off after approximately 4 seconds.
6. The meter defaults to the programmed conditions in use when the eter was last switched OFF.

Laser Pointer
The laser pointer circle identifies the area being measured. The size of the area is determined by the distance to spot ratio. Objects outside the circle are not measured. The spot measured should always be larger than the circle for accurate measurements.

MAX, MIN, AVERAGE, and MAX‐MIN
In the MAX MIN AVG mode the meter will record the Maximum value scanned, Minimum value scanned, the Average of the scanned values and the Difference between the  Max and Min value.

1. Turn Max Min ON in the settings mode
2. Press and hold the trigger to scan an area. Max, Min, Avg or Max‐Min will be displayed in the lower right display. Press the up button to select the parameter to be displayed. The values will be continuously updated for the length of the scan.

UV Leak Detector
Inject a small amount of fluorescent dye into the system under test.
The dye/system mixture (refrigerant, for example) will escape and accumulate at all leak sites. Turn the blue UV LEDs on in the Setting mode and scan the system. The residue  of the dye at the leak can be easily observed under UV light. Dyes are available at most HVAC supply outlets.

Locating Hot or Cold Spots
To detect a hot or cold spot, aim the thermometer at a region beyond the target and then scan the entire region in a slow, up/down motion.

Distance to Spot Ratio (Field of View)
The meter’s field of view is 12:1 (distance to spot ratio). For example, if the meter is 60cm (24 inches) from the target (spot), the diameter of the target must be at least 5cm (2  inches).
Note that measurements should normally be made further than 60cm (24 inches) from the target. The meter can measure from further distances but the measurement may be affected by external sources of light. In addition, the spot size may be so large that it encompasses surface areas not intended to be measured

Emissivity
Emissivity represents the energy reflectivity of a material. Most organic materials and painted or oxidized surfaces have an emissivity of approximately 0.95. If possible, masking tape or flat black paint should be applied to cover the measured surface.
Wait a period of time to allow the tape or paint to reach thermal equilibrium with the surface of the covered object. Measure the temperature of the surface covered with tape or paint only after equilibrium has been achieved.

High Low Limits
The HI/LO limits provide an alarm when a preset temperature is exceeded.
