Other Information

Calibration Reminders

As a service to our customers, one month before your equipment reaches its recalibration anniversary, we will automatically send a letter to the person whose name is on record as the contact individual at your company advising this fact and the cost and procedure for recalibration.

Your next step is to contact us to order the Calibration Service.

Note 3: Effective January 1, 2018, calibration services for serial port models M3 and M3A will require that the tester be upgraded to USB.



Unexpected Repair

If our technicians discover that a repair is needed, the tester will be set aside while you are contacted for approval to repair and (if either the repair is not covered under the warranty or if the tester is not under warranty) to charge for the repair. If you do not respond to a quotation within 10 business days, the product will be returned 'As-Is'. Repairs will be scheduled into the service queue as soon we receive your written approval. Calibration will be performed once the tester has been repaired.

Calibration Documentation

The equipment will be returned with a new calibration sticker and an installation drive. The installation drive contains the calibration data file and, if you also renew your warranty, the latest software release. Replace your existing calibration file with the new one. Customers will find installation instructions at Customer Support.

Frequently Asked Questions (FAQs)

Why is calibration necessary?

To ensure that resistance measurements remain accurate, we suggest yearly calibration. Certain components within CableEye Models M3 series, M4, and HVX series are analog components whose characteristics change slightly over time. This aging is a natural phenomenon common to all electronic components and may cause resistance measurements to gradually deviate from normal.

Companies interested in quality product and maximum yield will ensure their testers are calibrated. Those with quality certifications such as Six Sigma or ISO9000 will be required to calibrate.

A tester that is out of calibration will give inaccurate results. Some (maybe all) resistance measurements will be incorrect. Consequently, it may Pass what should Fail and, conversely, Fail what should Pass. In other words, product yield will be contaminated due to unreliable quality.



Note 1: Calibration is NOT required for M2 series models as they do not have resistance-measurement components/functionality.



Note 2: All HVX series testers undergo a general inspection and cleaning before calibration. Our trained experts remove the cover (not otherwise necessary for calibration alone), inspect, clean, and check for the need to install any applicable firmware upgrades (three microcontrollers inside).



There are no embedded resistors in our cables. Can we skip calibration?

The resistance-measuring feature of the testers is used when measuring the quality of the connection and the quality of the non-connection … as well as measuring any embedded resistors. While your products may not have embedded resistors, there is still every reason to measure the quality of the connections and non-connections, thus resistance measurement is necessary.

Dual threshold set-up is required to check for connection quality. If your testers are set up for dual threshold then, by default, they are set up for resistance measurement.

If they are not set up for dual measurement, we would recommend you do so, otherwise your tester tells you when your intended connection is connected (passing a simple continuity check), but not whether that connection is compromised by something that affects the total resistance of that connection - perhaps, for example, because of poor soldering. This is explained in Chapter 4 of the Manual, sections 4.1 and 4.2.

In short, resistance measurement capability within a tester is not simply for measuring the values of resistors and you need to calibrate your tester even if there are no embedded resistors in your cables.

How do we install a calibration file?

Customers will find these instructions at Customer Support.


Do you offer As-Found calibration data service?

Yes, it is a non-standard calibration service option, and it may add up to one business day to your overall calibration service. If this is a requirement, be sure to mention it when you call for your calibration quotation and to include it on your PO when you book your service. It is imperative that your purchasing department email us this PO in advance of shipping the unit to us. See above for complete ordering details.

The PO must be emailed to us in advance of shipping the unit.




Our QC department wants us to verify the tester is within calibration each month. Can we do that?

Yes, if you purchase our optional Resistance Calibration Verification board viz. item 780A.

If your tester is fitted with the 4-Wire Kelvin Measurement Add-On option, you will also need the 4-Wire Calibration Verification Board (item 782).

CAMI Research has some of the best customer support and response times of any of our vendors, and I want you to know that this is truly and sincerely appreciated.

Can we calibrate CableEye testers by ourselves?

Yes, if you purchase a Calibration Kit/s. The Low Voltage (LV) kit is required for every tester (except the M2U series for which calibration is not applicable). It includes a calibration board with precision reference resistors, special software, a procedure, and cables. In addition, you will need your own benchtop Digital Multimeter that resolves to 0.1mV and is calibrated to NIST standards. If your tester is equipped with a capacitance measuring capability, then you will also need a Precision Capacitance Decade Box that is calibrated to NIST standards. We recommend Item 717C or an equivalent device.

To calibrate HVX-series testers, order a LV kit together with an appropriate High Voltage (HV) kit. HV kits include further software, a procedure, and special voltage-divider switch box/es.

Calibrating a CableEye tester does not involve adjusting trimpots or any other mechanical adjustments. Instead, special software makes precise measurements under known conditions and computes a set of "calibration constants" within a defined tolerance for each test point. The resulting calibration file is generated at the end of the procedure. You then place this file, ending in ".cal", in your /Program Files/CableEye/Software folder. When the CableEye application starts, it looks for this file and uses its data to compensate for slight variations in the semiconductors.

In the unlikely event that the calibration software computes constants that lie outside of the predefined tolerance, the software stops, fails the calibration, and notifies the technician, asking whether s/he wishes to retry. If the calibration fails again, the equipment will need to be repaired by CAMI personnel.

Regardless of annual Warranty status, Technical Support is billable for issues resulting from improper use of the calibration procedure. A minimum charge applies. Such support includes, but is not limited to, email, online chat, phone support, Skype, and TeamViewer and any consequent service such as repair and recalibration.

In general, if your company has two or more CableEye testers and intending to calibrate yearly, it may be worth the cost and technician time to purchase the calibration kits. However, for HVX series testers in particular, we highly recommend you return your tester to us for factory calibration once every couple of years in order to benefit from the general inspection and cleaning described in Note 2 above.


Note 4: In addition, you will need your own benchtop Digital Multimeter that resolves to 0.1mV and is calibrated to NIST standards. If your tester is equipped with a capacitance measuring capability, then you will also need a Precision Capacitance Decade Box that is calibrated to NIST standards.

Note 5: When self-calibrating an HVX series model, the unit will not benefit from the services of 'Note 2' above.



The reliability of the equipment allows us to provide our customers with the best possible products. We've also found that the customer service and response time from CAMI Research to be excellent. All in all a company I would highly recommend using.
