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 flash "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.
