Overview

The AK-4.10000.5Y Automatic Mass Comparator is used for automatic determination of weights mass deviations with the minimum possible participation of the operator. The device allows the determination of mass deviations of up to three tested mass standards with masses from 500 g to 10 kg in one cycle. The AK-4 series sets the highest standard for professional automatic mass comparators.

It has a 4-position standard magazine . The positioning mechanism guarantees extremely precise positioning of the mass standard on the weighing pan with each rotation of the turntable. The unique design of the weighing pan makes it possible to determine the weight deviations of both one mass standard and two or even three mass standards in a single cycle. A mechanical weighing range switch allows the comparison of mass standards over a wider load range while keeping the resolution of the comparator constant. The standard equipment of the AK-4 mass comparator (except the AK/10000) includes an additional anti-draft chamber . The advanced 5Y terminal makes work much easier with its 10’ display and various interfaces.

Fully secure login and user verification system using passwords, RFID* tags, fingerprint reader or face recognition mechanism Continuous monitoring of the load on the weighing pan Quick access to commands Numerous widgets Communication with external devices thanks to wide range of interfaces Working modes tailored to your needs History of the last 20 measurements always at hand Constant monitoring of ambient conditions.

Maintenance contract — AxiTech provides planned preventive maintenance for AK-4.10000.5Y Automatic Mass Comparators from Radwag: scheduled visits, safety checks, periodic calibration and a documented service report, backed by a contractual response time.

Troubleshooting, repair and spare parts — our laboratory balances engineers diagnose and repair AK-4.10000.5Y Automatic Mass Comparators on site or in the workshop, fit genuine spare parts and recommission the equipment after performance verification.

Maintenance contracts for AK-4.10000.5Y Automatic Mass Comparators

AxiTech provides preventive maintenance contracts for AK-4.10000.5Y Automatic Mass Comparators. Each contract fixes a schedule of planned visits in which our biomedical engineers inspect the equipment, replace wear parts before they fail, and verify that it still performs inside the manufacturer’s tolerances.

Every visit includes calibration and performance verification, and closes with a documented maintenance report you can present during an accreditation audit. Spare-parts availability and a guaranteed response time are written into the contract, so a breakdown never leaves a department waiting for an answer.

Laboratory analysers are usually maintained every three to six months, with calibration and quality-control verification at each visit so that results stay traceable.

  • Planned preventive maintenance visits at a fixed interval
  • Calibration and performance verification against the manufacturer’s specifications
  • A documented maintenance report after every intervention
  • Guaranteed availability of spare parts and consumables
  • A contractual response time when the equipment fails

Troubleshooting and repair for AK-4.10000.5Y Automatic Mass Comparators

When AK-4.10000.5Y Automatic Mass Comparators fails, our engineers start with a structured diagnostic: error codes, electrical and mechanical checks, and a functional test against the equipment’s own specification. That tells us whether the fault is a consumable, a worn part or a board-level failure before any part is ordered.

Straightforward faults are repaired on site so the department loses as little time as possible. Anything that needs a workbench, a full strip-down or a specialised spare part goes to our workshop and comes back only after a complete post-repair test and, where the equipment requires it, recalibration.

Faults we see most often on this type of equipment

On analysers most faults come from the fluidics — blocked probes, worn pumps and tubing, leaking valves — followed by optical drift and reagent-handling errors.

Troubleshooting

How to troubleshoot AK-4.10000.5Y Automatic Mass Comparators

Work through these checks before you escalate. They are the same first-line sequence our biomedical engineers run on arrival, and they either clear the fault or narrow it down enough that the intervention starts with the right spare part in the van.

  1. Capture the fault before you touch anything: write down the exact error code or message, the serial number from the rating plate, what the operator was doing and whether the fault clears on a restart.

  2. Review the quality-control and calibration history. A result that has drifted across several runs points at calibration or reagents; a sudden shift almost always points at the fluidics.

  3. Inspect the fluid path — probe, tubing, pump, valves and waste line — for blockage, crystallisation or leaks, and confirm reagent and wash levels together with their expiry dates.

  4. Confirm the ambient conditions the method depends on: bench temperature, ventilation, a level and vibration-free surface, and a stable mains supply.

  5. If the fault is still there, escalate with the evidence. Send AxiTech the model, serial number, error code and the checks you have already run, and an engineer will come back with a diagnosis, a repair quote and a spare-parts lead time for AK-4.10000.5Y Automatic Mass Comparators.

What to send us when you report the fault

  • Manufacturer, model and serial number, from the rating plate
  • The exact error code or message, and the screen it appears on
  • When the fault started, how often it occurs and what triggers it
  • A photograph of the display or of the fault, and the last maintenance report

If the fault survives all five steps, stop using AK-4.10000.5Y Automatic Mass Comparators and open a repair request. Continuing to run equipment through a fault it cannot clear turns a component failure into a board-level one, and on devices used for diagnosis or therapy it puts the result — and the patient — in doubt.

Buying and installing AK-4.10000.5Y Automatic Mass Comparators

AxiTech supplies AK-4.10000.5Y Automatic Mass Comparators together with the accessories and consumables it needs to enter service. We handle importation, delivery and installation, then commission the equipment on site so that it is verified against its specification before the first patient or the first sample.

Installation is followed by training for the users and for your biomedical team, warranty registration, and — if you want it — a maintenance contract that takes over the day the warranty ends, so the equipment never spends a period without planned service.
