About the GHL Logbook #
The Logbook is your digital notepad for recording various tasks, events and reminders. With the Logbook, you can record your tests results from manual tests. As you continue recording these results, the Logbook will automatically add these data points to a clean, easy to read chart.
Available for all GHL core products
The Logbook tool is available to all ProfiLux, Standalone Doser and Mitras LX owners who use the GHL Connect app and myGHL to access their device.
Logbook entries are synced across the app and myGHL
As long as you have your GHL device added to your myGHL account, you can work in the Logbook using any connection option you want (app-Wi-Fi, app-hotspot, or myGHL). All your entries are automatically synced across the app and myGHL.
Create a Logbook category #
About category types
The option you should choose will depend on what exactly you’re looking to record into the logbook.
Here’s a breakdown of each option:
- Note: Choose this option to record simple notes
- Measurement value: Choose this option if you want to manually record test kit results
- Maintenance: Choose this option if you want to record “maintenance” related events
- Reminder: Choose this option if you want to setup reminders
*** IMPORTANT ***
In order to give you the most details about the logbook setup process, we’re going to choose the “Measurement value” category type so you can see how one sets this up. The setup steps for other category types are similar.
5. Choose the parameter you want to use
6. Choose the color you want to use for this category
7. Type-in any comment or notes you want to add for this category

8. Choose the unit of measure to use for this parameter
9. Choose the number of decimal places to use for this parameter

Choosing the right number of decimal places
The number of decimal places you should choose depend on the parameter you are creating the category for. Use the preview field as a guide for selecting the correct number.
For example, if you are creating a category for calcium, you would choose (0) decimal places because calcium is measured in whole numbers; 400, 395, 405, etc.
If you are creating a category for Phosphate, you would choose (2) decimal places so you can record values like 0.02, 0.04, 0.15, etc.
Recording events #
Once your categories are created, you can go ahead and begin recording events.
