This official Hochoice balance calibration and maintenance guide provides recommended schedules for all Hochoice precision and analytical balance models. Following these routines ensures optimal accuracy, extends service life and maintains compliance with QC and regulatory requirements.
Calibration frequency depends on usage intensity, environment and accuracy requirements. Adjust based on your actual workload:
| Usage Scenario | Recommended Calibration Cycle | Verification Check |
|---|---|---|
| High-volume QC lab (daily use, multi-shift) | Every 2 weeks | Daily zero check + weekly weight verification |
| General R&D lab (regular daily use) | Every 4 weeks | Daily zero check + bi-weekly weight verification |
| Occasional use lab (1–2 times per week) | Every 8–12 weeks | Zero check before each use |
| Regulated pharmaceutical QC lab | Every 2 weeks, documented | Full performance test quarterly |
Check level bubble and adjust if needed
Inspect weighing pan for cleanliness and debris
Close draft shield and perform zero reset
Verify stability indicator is functioning
Thoroughly clean weighing pan, draft shield and chamber interior
Verify level at all four corners of the bench
Check power cord and connections
Perform single-weight verification check
Perform full electronic balance calibration with certified traceable weights
Inspect foot screws and leveling mechanism
Clean exterior and display panel
Review calibration logs and verify records
Perform full multi-point calibration across the range
Test eccentric load performance at four pan positions
Inspect sensor housing for dust buildup
Verify repeatability meets specification
✅ Never exceed maximum rated capacity
✅ Always preheat 30 minutes before use
✅ Keep the balance plugged in on standby for daily use
✅ Avoid moving the balance unless necessary
✅ Recalibrate after any relocation or major environment change
✅ Have professional service once per year for high-precision models
