Insert the optional Type K probes into the T1, T2, T3, T4 input sockets. The screen will show the 4 channels (T1, T2, T3, T4) and their temperature values. If an input socket is empty, the screen will display “- – – – -”
Type J/T/E/R/S Measurement
You can change the temperature sensor by pressing the “Type” Button. The following icons will show on the display: “J/T/E/R/S”. Insert the optional Probes into the T1, T2, T3, T4 input sockets. The screen will show the 4 channels (T1, T2, T3, T4) and their temperature values. If an input socket is empty, the screen will display “- – – – -”.
Pt 100 ohm Measurement
Using again the “Type” Button until the screen displays “Pt” you are able to change the Temperature Sensor. Insert the optional Pt 100 ohm Probes into the PT1 and PT2 input sockets. The screen will show the temperature values.
T1-T2 Measurement
With this Reed SD-947 4 Channel Thermometer Datalogger you are able to made T1-T2 measurements. Start using this by inserting the two probes into the meter, either a Thermocouple Probe in the T1 & T2 sockets, or a Pt 100ohm Probe in the PT1 & PT2 sockets. Continue by pressing the “T1-T2” button and the display will show the difference value between T1, T2 (or PT1, PT2) on the bottom right of the screen.
Data Hold
To freeze on the screen the measured value, while taking a measurement, press the Hold Button once. Now the display will show the “HOLD” symbol and the measured value. Press the Hold Button once again will release the data hold function.
