Calibrate CableEye testers at your facility using this item.
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 CableEye 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.
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 software. 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 that comes with factory calibration service.
