The Weight Log is a full history of an inventory item's weight. It records weights entered by hand, such as a measurement taken on a scale, and weight changes that happen during runs, such as adding a component to an assembly or a temporary installation.
Each entry shows how much the weight changed (Amount), the item's weight after the change (New Total), who made it, and where it came from (Source).
Find the Weight Log
Navigate to Builds > Inventory and click into an inventory item
Click the Execution tab
The Weight Log shows all weight entries for the item
The top of the Weight Log adds up the item's weight: Baseline + Updates = Current Total.
Updates are the weight changes since the baseline, such as installed or removed components. The newest measurement and its date are shown to the right
A measurement is kept for reference and is not part of the Current Total.
Use the Rounded toggle to switch between rounded and exact weights. Click Export to download the log.
Baselines and Measurements
The Weight Log has these kinds of entries:
Baseline: the official weight of the item.
Measurement: a weight reading kept for reference, such as a check during an operation. A measurement does not change the item's official weight.
Install and Remove: a weight change from adding or removing a component, such as an Update Components block in a run or a temporary install. These add up as Updates at the top of the log.
Correction and Void: a fix to, or cancellation of, an earlier entry.
Each baseline or measurement is also marked as Measured, Estimated, or Imported, so you can tell a scale reading from an estimate.
Add a weight entry
In the Weight Log, click Add Entry. The Record Measurement window opens.
Enter a name for the entry.
Enter the weight and pick the unit: grams (g), kilograms (kg), ounces (oz), or pounds (lb)
Choose Measured, Estimated, or Imported from the drop-down.
Select the scale used (optional)
To make this the item's official weight, check Set as New Baseline. The window changes to Record Baseline.
Optionally, add an attachment, such as a photo of the scale reading, and a comment
Click Record Measurement (or Record Baseline)
A measurement doesn't change the item's Current Total. The newest one shows as the Latest measurement at the top of the log.
To make a measurement the item's official weight later, open its 3-dot menu and select Promote to Baseline.
Correct, void, or resolve an entry
The same 3-dot menu you use for Promote to Baseline also lets you view details, correct, or void an entry. If an entry’s weight shows as Unknown, the menu also has Resolve.
Correct: change the quantity or unit weight of an entry, for example, when the wrong number was typed. A reason is required. The fix is added as a new Correction entry, and the original stays in the log, crossed out.
Void: cancel an entry. A Void entry is added, and the original stays in the log, crossed out. If the voided entry was the current baseline, the item's weight goes back to the previous baseline. Entries that came from a run can't be voided. Use Correct instead.
Resolve: when an entry's weight shows as Unknown, for example, a component with no unit weight, enter the missing unit weight. The original stays in the log, crossed out.
To see why an entry was corrected or voided, hover over the speech bubble on the Correction or Void entry.
Weight changes from runs
These actions add entries to the Weight Log automatically:
Changing the weight in an Inventory Details block during a run
Adding or removing components on an assembly with an Update Components block
Temporary installs and removals (see Temporary Install / Remove (TIR) Logs)
Component changes show in the log as Install or Remove entries, with a link to the run in the Source column. They add up as Updates at the top of the log.
Weight Logs and assembly weight
For assemblies, Epsilon3 also adds up component weights automatically. See Automatic Weight Aggregation for Assemblies in Parts Inventory.
