How To Calibrate Your Eltra 84 Balance
The Eltra 84 Balance for the weighing of samples comes standard with new Eltra analyzers.
For the full user manual, please e-mail instrumentsales@eltra-africa.co.za.
Here is a quick guide on how to calibrate your Eltra 84 Balance.
Calibration/Adjustment
Calibration/adjustment can only be performed when
– there is no load on the balance,
– the balance is tared,
– the internal signal is stable.
If these conditions are not met, an error message is displayed. Otherwise, the weight
required for calibration/adjustment is displayed.
You can use the test weight provided for calibration/adjustment; however, we
recommend using a weight of a higher accuracy class as listed below.
Weight Supplied/Recommended Weight:
| Balance Model | Eltra 84 |
| Test Weight Provided | 50g |
| Accuracy class/tolerance | F1/±0.3 mg |
| Recommended calibration weight | 50g |

You can use either of the following weight units to calibrate/adjust:
