Power ON/OFF
The meter automatically powers on when the trigger is pulled. Pull
the trigger to take a reading. Read the measured temperature on
the LCD. The meter powers OFF automatically approximately 6
seconds after the trigger is released.
Selecting Temperature units (C/F)
Select temperature units by pulling and holding the trigger, then
press the C/F key until the desired units are shown on the LCD.
Data Hold
The meter automatically holds the last temperature reading on the
LCD for 6 seconds after the trigger is released.
Backlight LCD
Select backlight by first pulling the trigger and then pressing the
BACKLIGHT key. Repeat the procedure to turn the backlight off.
Laser Pointer
To turn the laser pointer ON, press the LASER key while pulling the
trigger. Repeat the procedure to turn the laser OFF.
Measurement Considerations
Point the IR Sensor toward the object whose temperature is to be
measured. The meter automatically compensates for
deviations from ambient temperature. However, the meter will take
up to 30 minutes to adjust to wide ambient temp. changes. This
results from the need to acclimate the IR sensor.
Battery Replacement
A flashing display indicates that the battery voltage has fallen into
the critical region (6.5 to 7.5 V). Reliable readings can be obtained
for several hours after the first appearance of the low battery
indication. Open the Battery Compartment and remove the battery,
then install a new 9V battery and reinstall the cover.
Maintenance
Case cleaning
Use caution with a damp cloth to clean the exterior housing, ensure
no water or soap is allowed inside the meter and on the infrared
lens.
Lens cleaning
Keep the lens clean to ensure reading accuracy. Use low pressure
compressed air to remove any particles on the lens. If the
contamination can not be removed with air, use a soft cotton swab.
Any swab should be slightly damp, and very light pressure should
be applied to the lens.
Do not use solvents to clean the lens.
