1. What are the test pieces intended for?
The test pieces are used to check the level of detection of inductive metal detectors and X-ray detectors.
The everyday use of Multitesters allows an optimum and precise adjustment of detectors, ensuring that only defect-free products are accepted in the production process.

2. How often can Multitesters be used?
The frequency of testing detectors installed on production lines, as well as the procedure for using Multitesters (including the total number and sequence of testing as well as the procedures following a given type of result) are determined by the User's internal regulations, taking into account the Hazard Analysis and Critical Control Point (HACCP) system, procedures set by its Quality Department and standards imposed by the client (e.g. a retail chain). If the procedures do not state the precise rules for inspecting the correct operation of the detection equipment, we recommend to consult our Customer Service Department. Our consultants will help you to select the products and frequency of the tests directly at your manufacturing site.

3. Can the test pieces be used to calibrate a Metal Detector and an X-Ray Detector?
No, the test pieces were not designed to calibrate the detectors.
The test pieces are used for checking/validation of detection and detector performance.

4. How to match the type of test piece to a given product?
While selecting a test piece for your manufacturing line you need to know answers to two questions:

4.1. What type of detector is being used (MD or X-ray)?
A test piece for inductive metal detectors may contain a considerable amount of plastic in the housing of the metal sample as plastic does not trigger the detector. X-ray test pieces must be made of a material which absorbs some radiation in order to ensure that the housing of the material being tested (metal, glass, stone, rubber, bone) remains neutral for the detector, i.e. to ensure that it did not interfere with the analysis of the x-ray image. Our web store makes it easier to correctly match the type of test piece to a given type of detector. Select one type of a detector, i.e. x-ray or inductive metal detector or choose the detector brand and the system will automatically select suitable test pieces.

4.2. Which products can be tested?
We offer a wide variety of test pieces suitable for specific types of products, as well as the potential packaging, i.e.: we recommend test rods for glass packaging, cubes for confectionery, bars/spherical or card test pieces for the meat industry, etc. Our web store makes it easier to correctly match the type of test piece to a given type of detector. Select one type of detector, i.e. x-ray or inductive metal detector or choose the detector brand and the system will automatically select suitable testers.
Taking the time to select a proper Multitesters test piece will save time required to measure the performance of the detector.
The product data sheets available at www.multiresters.com contain information on recommended products for the test pieces.
We provide technical support in selecting test pieces. Please contact the Customer Service at 81 381 42 61 or via e-mail: bok@multitesters.com

5. What is the expiration date of the Multitester?
The housing of the test piece as well as the material placed inside the probe are covered by a 5-year warranty on chemical composition, shape, size as well as physical and chemical properties. After the expiry of that period, we recommend replacing the test pieces due to possible loss of physical and chemical properties, which in turn may cause decreased precision.
If a test piece is mechanically damaged by falling, crushing or due to extreme temperatures, we strongly recommend to replace the test piece with a new one, free from defects.

6. How to match the contaminant in the test piece to the tested product?
The contaminant used in the Multitester test piece must be selected taking into account the risks associated with the product and the production process, as well as the type of technology
the detector (i.e. inductive - only metals, x-ray - including other materials as well). The standards set by the Quality Department or HACCP specify which contaminants may potentially occur in the production process. The most common risk involves contaminating a product with metals, therefore for practical reasons, a metal test piece is typically used to verify the performance of virtually all detectors. If the internal standards at your facility do not specify other types of contaminants which may be present in your products, please refer to the guidelines provided in the DOWNLOAD below: Potential contaminants - Guide

7. Quality Defects - is it possible to detect them using Multitesters?
Yes, 3D testers manufactured per custom requests allow to verify the performance of the device and to examine possible product defects.

Example of defects:
- no cream/other additives inside the product,
- correct shape,
- correct weight of the product,
- the size of the product,
- the number of products in a set
- the arrangement of the product

If you wish to order a test piece that matches the shape and properties of your products, we can design and manufacture a dedicated 3D test piece (the 3D testers tab).

8. How many test pieces should I buy in order to verify the performance of a detector?
The amount of contaminants tested is determined by the Quality Department Standards or analysis based on the HACCP system. If you have any questions regarding the selection of test pieces, please refer to the DOWNLOADS table below: Potential contaminants - Guide or contact our Customer Service.

9. What is the turnover time for orders?
The typical turnover time for standard test pieces available in our catalogue (except for Multicards, 3D testers and custom orders) in quantities up to 10 items is 24 hours. In the case of special orders, the turnover time is typically discussed with each customer and later confirmed via e-mail.

10. Is it possible to order a test piece that is not listed in your catalogue?
Yes, if our range does not include the product you are looking for, please contact our Customer Service. We will prepare a personalised offer and set a turnover time.

11. What is a Multicard?
The Multicard works only with X-ray detectors. Each Multicard comes either with several types of contaminants or with a single contaminant in several sizes. The type and size of contaminants are selected per customer's request.

12. Should I select a Multicard or a card with a single contaminant?
The Multicard speeds up the detector testing procedure as it tests the detector for different types and sizes of contaminants simultaneously. The Multicard, however, requires human interaction to carry out a visual inspection (checking the detector display for contaminant detection tags) to see whether the detector has successfully detected the contaminants and to ensure that the scope of detection is correct. The Multicard is therefore only recommended to be used with X-ray detectors and only for special applications which allow the precise identification of the detected contaminant.
A simple card with a single contaminant eliminates the need for carrying out daily visual inspections of X-ray detectors.
