Color Alert 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 a flashing red LED backlight, as well as 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.

Lock feature

The LOCK feature disables the Auto Power Off feature for a single period of use after the Lock

mode is 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.

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.
