Emissivity Adjust

The adjustable emissivity feature allows the user to measure many surface colors, finishes,

and textures. A separate section is provided later in this guide that covers emissivity in

greater detail.

Test Lock feature

The Test 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 using the MODE button. The

setting is stored and memory and will remain as the “turn-on” condition until changed.

Temperature Units

The temperature units can be set to °F or °C using the switch located in the battery

compartment.

Over-range Indication

If the temperature measurement exceeds the specified temperature range, the

thermometer will display dashes in place of a temperature reading.

Battery Replacement

When the low battery symbol

appears on the display, replace the

meter’s battery (9V). The battery compartment is located behind the

panel that surrounds the meter’s trigger. Open the compartment by

pulling the panel down from the trigger area. Replace the 9V battery

and close the battery compartment cover.
