Operating Instructions

Temperature 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 will change as the user scans various targets.

3. The ‘SCAN’ icon remains on until the user releases the trigger.

4. When the trigger is released, the reading will hold for approximately 7 seconds (HOLD

will replace SCAN on the LCD) after which the meter will automatically shut off. The

only exception to this is if the LOCK mode is set to ON.

Laser Pointer

The Laser pointer optimizes the user’s aim during scanning. To turn the Laser on/off:

1. Press and release the Trigger

2. While HOLD is on the display, press the laser button once to turn the Laser on or

off.

3. The laser icon will appear in the LCD when the Laser is on.

4. The status of the Laser is remembered by the meter and will remain as the ON

condition until changed.

Backlight

1. Press and release the trigger

2. While HOLD is on the display, press the backlight button once to turn the backlight

on or off.

3. The backlight will illuminate the LCD when the feature is enabled.

4. The status of the backlight will be stored in memory and will remain as the ON

condition until changed.

5. Note: The backlight will shorten the battery life; use sparingly and only as necessary.

Over-range Indication

If the temperature measurement exceeds the specified temperature range, the

thermometer will display dashes in place of a temperature reading.

The MODE button options

The MODE button is used to access the emissivity adjustment, unit of measure selection,

MAX-MIN feature, test-lock feature, and high-low alarms

1. Press and release the trigger

2. While HOLD is on the display, press the MODE button to enter the programming mode

and to step through and configure the following features. A blinking icon indicates the

feature is selected.

E= (Emissivity Value)

Press the ▲ or ▼ buttons to change the emissivity value from 0.10 to 1.00

C/F (Units of Measure)

Use the ▲ and ▼ buttons to select the unit of measure.

MAX-MIN (highest and lowest reading memory)

Press the ▲ or ▼ buttons to select MIN or MAX display

(Lock mode On/Off)

Press the ▲ or ▼ buttons to turn the lock feature ON or OFF.

(High Alarm On/Off)

Press the ▲ or ▼ buttons to turn the High Alarm feature ON or OFF.

(High Alarm setting)

Press the ▲ or ▼ buttons to set the high alarm limit value in the main display

(Low Alarm On/Off)

Press the ▲ or ▼ buttons to turn the High Alarm feature ON or OFF.

(Low Alarm setting)

Press the ▲ or ▼ buttons to set the Low alarm limit value in the main display.

Emissivity adjustment

An adjustable emissivity allows for accurate measurements on a variety of surface colors,

textures, reflectivity, and finishes. The topic of emissivity is covered in greater detail in a

subsequent section of this guide.

Temperature Units

The temperature units can be set to °F or °C in the programming mode using the ▲ and ▼

buttons

MAX (maximum) and MIN (minimum) Temperature display

The highest reading (MAX) or the lowest reading (MIN) encountered during a single

measurement scan is displayed in the lower left-hand display area on the LCD. Select MIN

or MAX in the programming mode using the ▲ and ▼ buttons

Lock feature

The LOCK feature disables the Auto Power Off feature for the period of use when

selected. The feature is useful for long term temperature monitoring and hands free use.

The meter will revert to auto power off if the trigger is pressed during a locked scan.

High and Low Alarm Feature

The meter has a programmable high and low alarm feature. When either alarm point is

reached the meter will alert the user via an audible beep and a blinking LCD display icon.

The alarm limit is set and the feature is enabled/disabled in the programming mode. The

setting is stored and memory and will remain as the ON condition until changed.

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. Measurements through transparent surfaces such as glass may not be accurate.

5. Steam, dust, smoke, etc. can obscure measurements.

6. The meter automatically compensates for deviations in ambient temperature. However,

it can take up to 30 minutes for the meter to adjust to extremely wide changes.

7. To find a hot spot, aim the meter outside the area of interest then scan across (in an up

and down or side to side motion) until the hot spot is located.

Field of View

The meter’s field of view is 12:1. For example, if the meter is 24 inches from the target

(spot), the diameter of the target must greater than 2 inches. Other distances are shown in

the field of view diagram. Measurements should normally be made as close as possible to

the device under test. The meter can measure from moderate 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.
