CALIBRATION REPORT

1. Title:
Calibration Report for Digital Weighing Balance

2. Equipment Information:
Equipment Name: Digital Weighing Balance
Model Number: DWB-200
Serial Number: 2025-AB123
Department: Analytical Chemistry Laboratory
Calibration Date: 05 May 2025
Calibration Performed By: Mr. K. A. Muzongondi (Lab Technician)

3. Purpose:
The purpose of this calibration was to verify the accuracy and precision of the digital
weighing balance to ensure it meets laboratory standards and complies with quality control
procedures.

4. Calibration Procedure:
Calibration was performed using certified Class 1 standard weights. The balance was tested
at three weight points: 10g, 50g, and 100g. Each weight was placed on the balance, and the
reading was recorded. The deviation between the standard value and the measured value
was calculated to assess accuracy.

5. Reference Standards:
- Class 1 Calibration Weights (NIST-traceable)
- ISO/IEC 17025:2017 calibration guidelines

6. Calibration Results:
Test Point (g) Standard Value Measured Value Deviation (g) Pass/Fail
(g) (g)

10 10.000 9.998 -0.002 Pass

50 50.000 50.001 +0.001 Pass

100 100.000 100.002 +0.002 Pass

7. Conclusion:
The digital weighing balance was found to be operating within acceptable limits of
deviation. The results indicate that the balance is accurate and suitable for continued
laboratory use. The next calibration is scheduled for May 2026.
