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.
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 "-----".
Zero Adjustment • For best results you should zero the light sensor prior to first use in a dark environment. To achieve this, place the light sensor end of the meter under a desktop or flat 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. 2. 3.
Auto Power Off To preserve battery life, the meter is programmed to turn off after 10 minutes of inactivity. Battery Replacement When the low battery icon appears on the left corner of LCD display, you will need to replace the batteries. Remove the battery cover using a Phillips head screwdriver, insert a new 9V battery and secure the cover.
