It includes an automatic internal calibration (isoCAL) function, allowing the balance to self-calibrate at set intervals to maintain accuracy. The weigh cell is described as “monolithic weigh cell technology” which gives stability, precision and durability. Large weigh pan: e.g., specification documents list a pan size of 400 × 300 mm for this model. The housing is designed to be robust and chemical-resistant for tough lab environments. Interface: it supports RS-232C / V24‐V28 serial interface for data logging, printing, external systems. Fast response time: average response stated < 2 s in one specification sheet. Tare function: full subtractive tare up to 100% of capacity is supported. Technical Specifications (typical) Based on the manual and spec sheet for this model: Capacity (Max): 34,000 g (34 kg) Scale interval (d): 0.1 g Linearity: ±0.2 g (typical) Repeatability (standard deviation): ≤ 0.1 g Pan size: ~400 × 300 mm Dimensions (W × D × H): ~313 × 532 × 120 mm Typical response time: ≤ 2 s Operating ambient temperature with isoCAL: 0 °C to 40 °C; without: +10 °C to +30 °C (from manual) Interface: RS-232C serial, 7-bit, various parity, 150-19200 baud. Applications & Use-Case Given its capacity (34 kg) and readability (0.1 g), this balance is suited for large-capacity analytical weighing rather than ultra-fine micro-weighing. Typical uses could include: Weighing bulk samples, large containers or vessels (e.g., large drums, tanks) where still a good accuracy of 0.1 g is required. Rsdpfsxrt N Hex Ad Ast Industrial laboratories, QA/QC, production where large items must be weighed with decent precision. Situations where the weighing pan size needs to accommodate large items (400×300 mm is relatively large). Environments where interface to computer/printer is needed for logging and traceability. Where regular internal calibration is a benefit to maintain accuracy over time without frequent manual external weight calibration.
