The balance requires a controlled environment with ambient temperature between 18°C and 23°C and relative humidity between 20% and 80% RH. A mandatory preheating period of 30 to 60 minutes is required after power-on to ensure accurate measurements.
- Temperature Range: Operate the balance within an ambient temperature range of 18°C to 23°C to maintain specified accuracy.
- Humidity Range: Maintain relative humidity between 20% and 80% RH to prevent condensation and measurement drift.
- Preheating Requirement: Allow a mandatory preheating period of 30 to 60 minutes after power-on before performing measurements.
- Calibration Requirement: Perform external calibration using a 10 g reference weight to ensure linearity and accuracy.
- Auto-Calibration Trigger: The balance automatically triggers recalibration when ambient temperature changes exceed 1.5°C or after 2 hours of operation.
To achieve accurate measurements, power on the balance and allow a 30 to 60 minute preheating period. Then perform external calibration with a 10 g weight before placing samples on the pan.
Required Equipment: 10 g External Calibration Weight
- Preheat Balance
Power on the balance and allow it to preheat for 30 to 60 minutes. - Verify Environment
Verify that the ambient temperature is between 18°C and 23°C and humidity is between 20% and 80% RH. - Calibrate Balance
Perform external calibration using the 10 g reference weight according to the balance's procedure. - Place Sample
Place the sample on the weighing pan and wait for the stabilization indicator to appear. - Record Measurement
Record the measurement after the reading stabilizes, typically within 2.5 seconds.
Does the readability of 0.01 mg remain consistent across both the 51 g and 120 g capacity ranges on the EB51-120G-01MG-R, or is there a performance trade-off at higher loads?
Yes, the readability value (d) of 0.01 mg is maintained across both the 51 g and 120 g maximum capacity ranges. The portfolio matrix confirms that repeatability and linearity deviation errors are standardized at ±0.02 mg for the full B series, indicating no degradation in precision when switching between ranges. The dual-range capability is designed to provide the same high-resolution performance irrespective of the selected capacity threshold.
What are the integration requirements for connecting the EB51-120G-01MG-R semi-micro balance to a laboratory LIMS or data collection system via its RS232 interface?
The balance features a bidirectional RS232 communication bus that directly connects to micro-printers, host computer terminals, and third-party LIMS systems. The product description specifies the hardware pipeline as standard but does not include protocol details; integration requires a compatible RS232 cable and appropriate software or driver on the receiving system. No further configuration steps are documented beyond establishing the physical connection.
Why does the EB51-120G-01MG-R require a 30-60 minute preheating period, and what operational risks arise if this warm-up is skipped?
The mandatory preheating threshold of 30 to 60 minutes after power-on is required to stabilize the electromagnetic force compensation sensor and internal electronics, preserving uncompromised semi-micro resolution linearity. Skipping this warm-up period can cause reading drift and inaccurate results during critical operations such as external calibration mass loading or trace specimen additions, as stated in the operational notice. The balance should only be zeroed and calibrated after the full warm-up cycle.
The EB51-120G-01MG-R semi-micro balance delivers 0.01 mg readability with dual-range capacity (51/120 g) and rapid ≤2.5 s stabilization, but requires strict environmental control (18–23°C) and a 30–60 minute warm-up period for optimal performance.
Positive
- Fast stabilization and high precision: Achieves ≤2.5 second stabilization with ±0.02 mg repeatability and linearity, enabling rapid and accurate trace mass determinations in semi-micro analytical workflows.
- Automatic environmental drift compensation: Built-in auto-calibration triggers recalibration when temperature varies >1.5°C or time exceeds 2 hours, reducing operator intervention and maintaining accuracy under fluctuating lab conditions.
Trade-offs
- Mandatory preheating period: Requires 30–60 minute warm-up after power-on before zeroing or calibration to ensure sensor thermal equilibrium and linearity; adds setup time for intermittent use.
- Narrow operating temperature range: Specified for 18–23°C ambient; deviations outside this range may degrade measurement accuracy, necessitating climate-controlled laboratory environments.
