Analytical Semi-Micro Balance 31/120g 0.01mg ATOMFAIR®

This balance requires a 30–60 minute warm-up period after power-on before calibration or use to ensure sensor linearity. Operation is restricted to 10°C–33°C and 20%–80% RH to maintain specified repeatability and linearity tolerances.

• Warm-Up Requirement: Allow 30–60 minutes of uninterrupted power-on time before performing zeroing, calibration, or sample measurements.
• Environmental Stability: Maintain ambient temperature within 10°C–33°C and relative humidity between 20% and 80% to prevent drift and ensure ±0.02 mg repeatability.
• Automatic Calibration Trigger: The internal isbl calibration system activates automatically when ambient temperature shifts by ≥1.5°C or when 2 hours have elapsed since last calibration.

This procedure ensures the balance reaches thermal equilibrium and performs an internal calibration before use. Following these steps prevents measurement drift and maintains dual-range accuracy.

Required Equipment: Atomfair EB31G-01MG-R-02 Analytical Balance, Stable, vibration-free laboratory bench

1. Power On and Warm Up
   Connect the balance to the 220V AC / 50Hz power supply and switch on the unit, then allow 30–60 minutes for the internal sensor to stabilize.
2. Verify Environmental Conditions
   Confirm the ambient temperature is between 10°C and 33°C and relative humidity is between 20% and 80% using a calibrated thermometer and hygrometer.
3. Initiate Internal Calibration
   Press the calibration key to trigger the isbl automated internal calibration, or wait for the system to auto-calibrate if a ≥1.5°C temperature shift or 2-hour interval has elapsed.
4. Confirm Calibration Completion
   Verify that the display shows a stable zero reading and that the calibration indicator confirms successful completion before proceeding to sample measurement.
5. Select Weighing Range and Mode
   Choose the desired dual-range readability (0.01 mg or 0.1 mg) and operational mode (standard, percentage, or parts counting) using the front panel controls.
6. Place Sample and Record Mass
   Gently place the sample on the Φ 90 mm pan within the draft shield, close the glass doors, and wait for the stabilization indicator before recording the reading.

The EB31G-01MG-R-02 offers dual-range readability of 0.01 mg/0.1 mg with capacities of 31 g/120 g, supported by internal automated calibration (isbl) triggered by temperature or time changes. However, it requires a 30–60 minute warm-up and operates within strict environmental limits of 10–33°C and 20–80% RH.

Positive

• Dual-Range Readability and Capacity: Provides 0.01 mg readability for semi-micro work and 0.1 mg for analytical work, with corresponding capacities of 31 g and 120 g, enabling versatile mass determination on a single platform.
• Internal Automated Calibration (isbl): The balance automatically recalibrates when ambient temperature shifts by ≥1.5°C or after two hours, maintaining measurement accuracy without operator intervention.

Trade-offs

• Mandatory Preheating Period: A warm-up of 30 to 60 minutes is required after power-on before the balance can deliver stable, accurate readings, delaying immediate use.
• Controlled Environmental Requirements: Optimal performance is confined to 10–33°C and 20–80% RH; deviations may compromise repeatability and linearity.
