Operate the balance on a stable, vibration-free surface with the draft shield fully sealed when using 0.01 mg readability. Allow a 30-minute pre-heating period after power-on to achieve electromagnetic core equilibrium before initiating calibration.
- Leveling Procedure: Adjust the leveling feet until the bubble spirit level indicates the balance is perfectly horizontal.
- Draft Shield Sealing: Confirm all three draft shield doors are closed during high-resolution weighing to eliminate air currents.
- Thermal Stabilization: Wait 30 minutes after powering on for the internal electromagnetic sensor to reach thermal equilibrium.
- Calibration Activation: Initiate the one-key internal calibration either manually or via automatic timer/temperature triggers to maintain precision.
This procedure describes how to set up and calibrate the balance for accurate weighing. Follow these steps after placing the balance on a stable bench and connecting power.
Required Equipment: Leveling feet, Draft shield doors, Calibration key
- Level the balance
Adjust the four leveling feet until the bubble spirit level indicates the balance is perfectly horizontal. - Connect power and warm up
Connect the balance to a power source and allow it to warm up for 30 minutes to stabilize the electromagnetic sensor. - Seal the draft shield
Ensure all three draft shield doors are fully closed to isolate the weighing chamber from drafts. - Initiate calibration
Press the CAL key to trigger the internal calibration routine, which compensates for temperature and time drift. - Verify calibration
Check that the balance displays the calibration confirmation and zero reading before proceeding with measurements.
How does the dual-range measurement capability of the ATOMFAIR FA2055 balance affect repeatability and linearity when operating at the higher 0.01 mg readability?
At the 0.01 mg readability level (max capacity 52 g), the FA2055 delivers a repeatability of ±0.06 mg and linearity deviation of ±0.06 mg. When switched to the standard 0.1 mg readability range (max capacity 210 g), both repeatability and linearity shift to ±0.6 mg. This trade-off allows researchers to choose between ultra-fine resolution for small samples or higher capacity with slightly relaxed precision.
What external data communication options does the FA2055 offer for integration into automated laboratory workflows?
The FA2055 is equipped with a standard RS232 digital output interface for direct connection to computer logging systems or peripheral lab printers. Additionally, it supports an under-hook weighing configuration for hydrostatic density kits, enabling gravimetric density measurements without requiring separate hardware.
What specific operational steps are required to reliably achieve the 0.01 mg semi-micro weighing accuracy on the FA2055 balance?
For 0.01 mg measurements, the three-door glass draft shield must be completely sealed to isolate the pan from ambient air currents and thermal drift. A 30-minute system pre-heating phase is mandatory to allow the electromagnetic force compensation core to reach thermal equilibrium before starting calibration. The balance also incorporates temperature-compensated internal calibration (timer or temperature-triggered) and front-accessible leveling feet with a bubble spirit indicator for proper horizontal alignment.
The ATOMFAIR FA2055 dual-range analytical balance combines rear-mounted EMFC sensor technology with fully automated internal calibration (timer/temperature triggered) to deliver 0.1 mg and 0.01 mg readability across 210 g and 52 g capacity ranges, housed in a volumetric three-door draft shield with RS232 output.
Positive
- Dual-range EMFC with auto-calibration: Rear-mounted electromagnetic force compensation sensor enables seamless switching between 0.1 mg and 0.01 mg readability; fully automated internal calibration triggered by timer or ambient temperature fluctuations eliminates manual weight handling errors.
- Volumetric draft shield and ergonomic display: Large three-door glass draft shield isolates the weighing chamber from ambient air currents; toggleable high-contrast LCD panel reduces optical strain during extended verification sequences.
Trade-offs
- 30-minute pre-heat for semi-micro mode: To achieve 0.01 mg readability, the draft shield must be fully sealed and the balance requires a 30-minute system pre-heating phase for the electromagnetic core to reach thermal equilibrium before calibration.
- Temperature-sensitive calibration triggers: Automated internal calibration activates on ambient temperature fluctuations, requiring stable environmental conditions to avoid unnecessary recalibration cycles during routine weighing.
