REED LM-81AM Operating Instructions 1. Power on the instrument by pressing the Power Button 2. Press the Unit Button to select unit that you want and then face the Air Flow Sensor to the source of wind 3. Allow time for reading to become stable and note the value indicated.

REED LM-81AM Auto Power Off In order to prolong the battery life, the instrument has an “Auto Power Off” function. The meter will switch off automatically if no buttons are pressed for around 10 minutes.

REED LM-81AM Battery Replacement When the left corner of the LCD display shows the low battery symbol, this indicates that replacement of the battery is then needed. However measurements could still be taken for another few hours before the meter becomes inaccurate. 1. Open the Battery Cover at the back of the meter and remove the battery 2. Replace with a 9V battery (alkaline or heavy-duty type) and reinstall the cover

Air Velocity Measurement

For the Air Velocity Measurements start using your Environmental Meter and select the Anemometer function by pressing the “Function Button”. Using the “Unit/Zero Button” choose the unit of the measurements and face the “Air Flow Sensor” to the source of wind. Wait a while until the displayed value becoming stable and note the value indicated.

Temperature Measurement (Thermocouple)
Using a a type K thermocouple probe plugg this into the “Thermocouple Input Socket”. With the “Temperature Function” selected contact the Thermocouple Sensor Head with the object being measured and the reading value will be displayed on the LCD display.

Humidity & Ambient Temperature Measurement
With the LM-8000 into the “Light Measurement” mode, press the “Lux/Ft-cd Button” to select the measurement’s unit (“Lux” or “Ft-cd”). Read the light measurements value on the display. For best results you should zero the light sensor prior to 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” setting the meter indication to zero.

Hold Function
Freeze the current value of the measurements by pressing the “Hold Button”. Press again to release the hold function.

Data Record Function
Start the Data Record function by pressing the “Max./Min. Button” once. With the REC symbol on the display the meter will show the MAX or the MIN records. Switch between MAX and Min value of the measurements by pressing the “Max./Min. Button”. To exit the memory record function, press the “Max./Min. Button” continuously for at least 2 seconds. The display will revert to the current reading.

How to use Reed Environmental Meter (SD-9300)

Air velocity/Temperature measurement
Plug the Probe Plug into the Probe Input and power on your Reed SD-9300. When the meter is on, press and hold the Function Button and choose “An” function for Air velocity/temperature measurements. Release the Function Button and confirm your selection. With the “Air velocity” function selected, change the Air velocity unit, by pressing and the Unit Button. The display will flash the units m/S, Km/h, mph, Knot, & FPM. Release the Unit Button to select the displayed unit. The selected unit will be saved as the default.Hold the Probe Handle and face the Anemometer Head against the measuring airflow source. The air velocity measurement value will be displayed on top part of the environmental meter’s display and the lower part of the display will show the air temperature value.

Humidity/Temperature measurement
Plug the Probe Plug into the Probe Input Socket, then power on the Environmental Meter by pressing the Power Button. Using the “function” button choose “rH” function. The top part of the Display will show the %RH value, and the lower part of the Display will show the temperature value.

Type K/J Thermometer measurement
Plug the optional Type K or J Thermocouple Probe into the Type K/J Probe Input Socket. Be sure the Air Velocity Probe is not plugged in. Select the “tP” function. The screen will display a “K”, meaning it is configured for a Type K thermometer probe. The measured temperature will now be displayed on the display screen.

Light Meter measurement
When the meter is off, plug the Probe Plug into the Probe Input Socket, then power on the meter by pressing the Power Button. Power on the instrument and select the “LIgHt” function. Hold the Probe Handle and face the Light Sensor against the measuring light source. The top part of the Display will show the light measurement value. Tochange the Light Meter unit, press and hold the Unit Button, while in the Light Meter Function. The display will flash the units LUX and Ft-cd. Release the Unit Button to select the displayed unit.

Sound Level measurement (optional probe required)
Plug the optional Sound Adapter Plug into the Probe Input Socket and power on the Sound Adapter. Power on the meter by pressing the Power Button. The meter’s Display will show the symbol “Sound” and is ready to take sound level measurements. The display will show the measuring sound value with unit “dB”.

Data Hold and Data Record (Max., Min. reading)
You can freeze the measurement value by pressing the Hold Button during the operation. Press the REC Button once to start the Data Record function. By pressing the REC Button you can switch between the REC MAX reading and the REC MIN reading for the minimum value of the measurements.

Datalogger
Using an optional SD card you can use the datalogger function of the instrument. The information can be logged using Auto Datalogger or Manual Datalogger mode. Using Manual Mode, you have to set the parameters, such as the sampling time, while using Auto mode the setting will be made automatically by the meter.
