How to use REED SD-3007 Thermo-hygrometer w/ type k thermocouple, data logger

Humidity/Temperature measurement
Plug the Probe into the SD-3007’s Probe Input Socket, then power on the meter by pressing the Power Button. Press and hold the Function Button and choose the “rH” function. With the meter connected with the probe, continue the humidity/temperature measurements by holding the Probe Handle and face the Probe Head against the measuring source. The top part of the Display will show the Humidity value, and the lower part of the Display will show the Temperature value.

Dew Point and Wet bulb measurements
Before use this Thermo-hygrometer for dew point test, using the function button select the “dP” position. Hold the Probe Handle and face the Probe Head against the measuring source. The top part of the Display will show the Dew Point value, and the lower part of the Display will show “dP”. For wet bulb measurements select the “_Et” function and repeat the Dew Point measurement procedure.

Type K/J Thermometer measurement
With your Reed SD-3007 turned off plug the optional Type K or J Thermocouple Probe into the Type K/J Probe Input Socket. Be sure the Probe is not plugged in. Now turn on the instrument and the screen will display a “K”, meaning it is configured for a Type K thermometer probe. Please then wait a moment for the meter and the measured temperature will now be displayed on the display screen. To change the meter to accept a Type J Probe, please see the Advanced Settings section.

Using the Data Hold and Data Record function
During any measurements you can hold on the screen the measured value by pressing down the HOLD button. Press Rec Button once to start the Data record function. With REC active the Reed SD-3007 records the min and max readings. To exit the memory record function, press the REC button for 2 seconds. The display will revert to the current reading.

Auto Datalogger
With the automatic datalogging function you save the measuring data and time information into the memory. Before using this feature you need to insert the optional SD card into the SD card socket. Start using the dataloggin by pressing the REC Button. After the REC symbol will appeared, the data values and time will be saved on the SD card. During the datalogging operation, if you press the Logger Button once you will pause the datalogging, the “REC” symbol will stop flashing. Press the Logger Button again to resume Datalogging, and the “REC” symbol will begin to flash again.

Manual Datalogger (Set sampling time = 0 seconds)
Set sampling time is to 0 second; Press the REC Button, and the “REC” symbol will appear on the LCD screen. Press the Logger Button, and the “REC” symbol will flash once and one Beep will sound, at the same time the measuring data along the time information will be saved in memory. The lower Display will show the Position (record) number, which is saved as well. To Change the Position Number; press the Down Button and the lower position number will flash on the display. Press the Up or Down Buttons to set the Position Number (1 to 99) to help identify the measurement location. The lower Display will show P x (x = 1 to 99). After the position number is selected, press the Enter Button to confirm. Stop Datalogging; press the REC Button for 2 seconds, and the “REC” symbol will disappear indicating the Datalogging function has stopped.
