2. Field Gauge LC20, all models
   
3. Process Meter LC30, all models

Things you will need:

1. A PC running Windows. 
   
2. FieldLab Desktop software version 1.24.7.0 or later installed on your PC. Download the latest version for free.
   
3. A Ralston Instruments Field Gauge, Process Meter, or FieldLab Digital Pressure Calibrator.
   
4. For wired connections: Use the provided USB cord.
   
5. For Bluetooth connections: A Bluetooth-enabled computer and a Ralston gauge with the Bluetooth radio option. 
6. For Zigbee wireless radio connections: A Zigbee wireless-enabled Ralston gauge and a wireless USB dongle (included with purchase of all Ralston Zigbee wireless-enabled devices).

1. Open FieldLab Desktop on your computer.

2. Power on your Ralston Gauge or Process Meter.

3. Connect your Ralston Gauge to your computer with the provided USB cable or wirelessly.

4. Select Data Logging from the main menu in FieldLab Desktop.

5. Select one or more connected devices, then select Add to Log Session.

In this example we are selecting one LC20 Temperature Gauge, and one LC20 Dual Sensor Field Gauge. We are selecting both the temperature and the pressure sensors for the LC20 dual sensor Field Gauge. 

Based on our selections, our log session will save two temperatures, and one pressure.

Optional: Adjust the settings before you start logging

Before you begin your logging session you can adjust the settings for:

1. Pressure Units - Choose from any universally accepted engineering unit or Custom Units as defined in FieldLab Desktop.
   
2. Temperature Units - Choose temperature units in °F, °C, °R, or K.
   
3. Session Duration - You can set your log session to automatically stop after a specified length of time, until a total number of points are logged, or use the default; manual stop.
   

Optional: Use a Custom Pressure Unit

If you have defined a Custom Pressure Unit in your Preferences, then the Custom Unit will appear at the bottom of this list. The Custom Unit does not have to be added to the gauge itself.  

Optional: Change the Graph View

Note: You can change the graph view any time during the logging session.

Entire Log

Setting the Graph View selection to "Entire Log" will show all the graph data from the time you started logging.

Scrolling

When you select "Scrolling", only the most recent graph data will be shown, and older graph data will scroll off the left side of the screen as time progresses. 

You can use the slider tool at the bottom of the screen to scroll back and view older graph data.

6. Select Start Logging

Once you've confirmed you have the desired settings for the logging session, select Start Logging to begin saving the data from your gauges to your computer.

7. Stop Logging

If you have the Setting for your log session set to Manual Stop, select the Stop Logging button when your session is finished. 

If you specified automated stop rules in the settings before beginning your log session, you will not need to select the Stop Logging button and FieldLab Desktop will stop automatically once the stop criteria you specified is met.

All data from your log sessions is saved to Data Sets. You can go to the Data Sets section of FieldLab Desktop to view and export the data from all of your log sessions.
