Operating Instructions
Power ON/OFF
Turn the instrument on or off by pressing the POWER button.
Selecting Measurement Modes
The LM-8000 offers 4 types of measurement modes:
• Air Velocity/Temperature
• Humidity/Temperature
• Type K Thermocouple Temperature
• Light Meter
1. When the meter is on, press the FUNCTION button to cycle
through the measurement modes. The display will ash "An" (for air
velocity/temperature measurements), "rH" (for humidity/
temperature measurements), "tP" (for type K thermocouple
temperature measurements), "LigHt" (for light measurements).
2. Release the FUNCTION button once the appropriate
measurement mode has been selected.
Air Velocity/Temperature Measurement
1. Select the "An" function (see Selecting Measurement Modes section
for details). In Air velocity mode, the display will show both Air
Velocity and Temperature simultaneously.
2. Press the UNIT button to cycle through the units of measurements
(fpm, m/s, km/h, mph and knots).
3. When selected, face the Air Flow Sensor to the source of wind.
Note: For the best results when using your instrument, make sure the
air stream and the sensor are aligned (±20 degrees maximum) and wait
approximately 3 seconds for the reading to stabilize.
4. When the readings are stable, note the measured value.

Thermocouple Temperature Measurement
1. Plug the optional Type K Thermocouple Probe into the thermocouple
input jack.
2. Select the "tP" function (see Selecting Measurement Modes section
for details). In this mode, the LCD display will only show the
thermocouple temperature.
3. Press the °C/°F button to select between °C and °F.
Note: If no thermocouple is connected, the meter will display "-----".
Relative Humidity and Ambient Air Temperature
Measurements
When the meter is introduced into a new environment, it will take a few
minutes to fully stabilize.
1. Select the "rH" function (see Selecting Measurement Modes section
for details). In "rH" mode, the display will show %RH and ambient air
Temperature simultaneously.
2. Press the °C/°F button to select between °C and °F.
Light Measurements
1. Select the "LIgHt" function (see Selecting Measurement Modes
section for details).
2. Press the Lux/Ft-cd button to select Lux or Foot-candle units of
measure.
3. Before taking measurements, a zero offset adjustment should be
performed (see Zero Adjustment section for details).
4. Hold the sensor toward the light source and note reading.

Zero Adjustment
• For best results you should zero the light sensor prior to rst use in a
dark environment. To achieve this, place the light sensor end of the
meter under a desktop or at surface to block any light. Press the
Unit/Zero button to perform the zero adjustment.
• The zero value can drift due to environment temperatures, battery
power, as well as various other reasons. It is recommended that the
zero be checked frequently using the above procedure.
Data Hold
1. While taking a measurement, press the HOLD button to freeze the
current readings on the display.
2. While in this mode a "HOLD" symbol will appear on the LCD.
3. Press the button again to resume normal operation.
Recording Maximum and Minimum Readings
1. Press the MAX/MIN button to enter recording mode as indicated by
"REC" on the LCD. The meter will now begin recording maximum
and minimum readings.
2. While in recording mode:
A) Press the MAX/MIN button once and the maximum value will
appear on the display as indicated by "REC MAX" and will
automatically update when a new maximum data value
is measured.
B) Press the MAX/MIN button again and the minimum value will
appear on the display as indicated by "REC MIN" and will
automatically update when a new minimum data value
is measured.
C) To exit recording mode and resume normal operation, press
and hold the MAX/MIN button for two seconds.
Note: When in recording mode the POWER button is disabled and the
meter cannot be turned off.
