Overview

WAY 5.5Y.KO mass comparators ensure the traceability of mass measurements and verify weights according to the requirements of legal metrology. For this reason, they are an obligatory working tool in calibration laboratories worldwide. The WAY 5.5Y.KO Manual Mass Comparators series are designed for the calibration of mass standards and weights according to OIML (R-111) recommendations.

These devices are constructed from an electronic module and a precision mechanical measuring system. The ring surrounding the weighing pan protects it not only from air-drafts, but also from impacts when the mass standard is placed on it. The weighing pan is made of high-quality, non-magnetic stainless steel and has centring marks for easy placement of mass standards.

The WAY 5.5Y.KO comparator has the following communication interfaces: USB-A (2), USB-C, HDMI, Ethernet, Wi-Fi ® , Hotspot and optionally the Radwag communication protocol. With these, you will connect to: Smartphone and tablet (Hotspot) Spreadsheet (USB-C) Receipt and label printer (Ethernet, Wi-Fi ® , USB-A) Computer and laptop (Ethernet, Wi-Fi ® , USB-A) Barcode scanner (USB-A) Additional screen, including projector (HDMI) Software on your PC (RES Radwag Extended SI Module) Keyboard and mouse.

With the 5Y terminal, the WAY 5Y.KO comparator has gained new features and functionalities, which are: User-friendly menus seen more clearly on the 10’ touch display DWA ® (Digital Weighing Auditor) Log-in via password, fingerprint, facial recognition, RFID tags* or a combination of these Ambient Light alerts Hotspot RFID Live Note text memos Voice commands to the device Handy measurement history within the Handy Library Widgets.

Maintenance contract — AxiTech provides planned preventive maintenance for WAY 5.5Y.KO Mass Comparator 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 WAY 5.5Y.KO Mass Comparator on site or in the workshop, fit genuine spare parts and recommission the equipment after performance verification.

Maintenance contracts for WAY 5.5Y.KO Mass Comparator

AxiTech provides preventive maintenance contracts for WAY 5.5Y.KO Mass Comparator. 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 WAY 5.5Y.KO Mass Comparator

When WAY 5.5Y.KO Mass Comparator 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 WAY 5.5Y.KO Mass Comparator

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 WAY 5.5Y.KO Mass Comparator.

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 WAY 5.5Y.KO Mass Comparator 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 WAY 5.5Y.KO Mass Comparator

AxiTech supplies WAY 5.5Y.KO Mass Comparator 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.
