SCHILLER AT-1 ECG Device Analysis Report

Device Identification

The device shown in the visuals is a portable ECG (Electrocardiogram) device used in the field of medical diagnostics. The device functions to measure heart rhythms and print this data onto paper via its internal thermal printer. Its design is compact and suitable for desktop use.

Brand and Model

Following an examination based on the red print and model number located in the upper right corner of the device’s front surface, it has been determined with 100% certainty that the device’s brand is SCHILLER and its model is AT-1. The control panel layout and the physical structure of the casing are fully consistent with the characteristic features of this model.

Originality

Upon examining the print quality of the brand logo on the device, the font characters of the keypad (membrane panel), color codes, and the casting quality of the casing, the product is assessed to be an original SCHILLER production.

Areas of Use

The SCHILLER AT-1 is suitable for use in healthcare institutions, hospital emergency departments, cardiology outpatient clinics, family health centers, and private practices. Its primary purpose is to record and print the patient’s cardiac electrical activities (ECG). It is used by medical personnel for diagnostic purposes.

Quantity Information

Only 1 main device is visible in the visuals. No accessories (ECG cable, electrodes, power cable, etc.) are visible attached to or alongside the device.

General Condition

The device is cosmetically used (second-hand). Its casing maintains its general integrity, but a yellowing or discoloration towards “beige/cream” tones can be observed in the device’s color, attributable to its age and use. Its general condition appears to be that of a device that has not sustained heavy damage, has completed its service life, or is still in use.

Physical Deformation

No visible deep cracks, breaks, or dents have been detected on the device casing. However:

• Accumulated dust and dirt are present on the edges of the keypad panel and between the hinges of the printer cover.
• There may be light superficial marks on the device surface due to use, but no prominent, deep scratches are visible in the image.

Mechanical Components

The thermal printer compartment lid and the lid release latch, located on the upper left side of the device, appear mechanically in place and sound. No misalignment of the lid is observed. The paper exit roller (cylinder) is visible at the edge of the lid.

Electronic Components

There is no LCD screen on the device’s front panel; instead, an interface with LED indicators is used. Since the device is off (power disconnected) in the visuals, the operational status of the LEDs cannot be confirmed. However, the symbols indicating electronic functions on the keypad are legible. The patient cable (ECG cable) input port located on the side appears physically robust.

Accessories

The analysis in the visual is limited to the main unit only. Although a black cable end is visible in the background of the photo, it should be considered “Missing” as this cable is not attached to the device, and it is uncertain whether it is a part of the device (it could be an out-of-frame object). Therefore:

• ECG patient cable (bulbs and clamps): Not Visible/Missing.
• Power cable: Not Visible/Missing.
• Thermal paper: It cannot be determined from the visual whether there is paper inside the printer compartment.

Battery Status

A battery icon (Battery Indicator) is located on the lower left of the panel. This indicates that the device is equipped to operate with an internal battery or has a rechargeable battery. The current capacity of the battery, whether it holds a charge, or if it is swollen, cannot be seen externally.

Label and Panel Information

The technical function buttons and indicators located on the blue membrane of the device’s front panel are as follows:

• Speed Settings: 5, 25, 50 mm/s options.
• Sensitivity (Gain): 5, 10, 20 mm/mV and “AUTO GAIN” option.
• Derivation Indicators: I, II, III, aVR, aVL, aVF, V1, V2, V3, V4, V5, V6 indicators.
• Filters: MYOGRAM filter (FILT button) and “FILTER” LED indicator.
• Operation Buttons: AUTO START, MAN START (Manual Start), STOP, COPY (Copy).
• Status LEDs: PAPER (Paper out/error), ELECTRODE LEAD OFF (Electrode detachment), Battery, Mains (Mains power).
• Right Side Panel: The “Defibrillation-proof type CF applied part” symbol (heart icon within a box) is present. This indicates a standard specifying that the device can remain connected to the patient during defibrillator use and is safe.

Dimensions and Compatibility

The device is compact, in the portable class. Based on the proportions in the visual, it is estimated to be approximately thicker than a laptop but similar or slightly smaller in surface area. It has a standard ECG port that can be compatible with both adult and pediatric electrodes (when appropriate settings and accessories are used).

Year of Manufacture

No clear label indicating the date of manufacture is present in the visuals. However, this model (AT-1) is one of SCHILLER’s classic models, and its design reflects technology from the late 90s or early 2000s.

Documents

No user manual, invoice, service form, or warranty certificate for the device is present in the visuals.

Current Faults

During visual inspection, no definitive evidence of a fault such as “broken parts” or “burn marks” belonging to the device has been found. The paper cover is in place, and the keypad maintains its integrity.

Potential Fault Risk

Given the device’s age and “used” condition, besides the electronic components, ordinary wear and tear such as the membrane keypad losing sensitivity over time or the thermal print head aging may occur. Although the device appears clean, it may require professional calibration and battery replacement. Buyers are advised to consider these types of consumable expenses.
