Cable Length Meters
The cable length meters of PCE instruments provide various functions that can be useful in terms of measuring the length of cables or detecting cable breaks. Therefore the cable length meters function according to various measuring principles that will be described below. Using these devices enables determining cable lengths as well as the resistance and caliber of cables that are about to be laid or even already laid. Depending on the device that is being used, you can measure the length of cables to certain extends. Also the measuring ranges differ among the the devices. The cable length meters are applicable in different areas including industry, crafting, retails of electronics. Basically anywhere the length and quality of the cable needs to be measured. For some devices, there are electronic software's that can be downloaded from the internet for free. Those allow visualizing the collected data afterwards. These software's are not mandatory in order to operate with the cable length meters, since they often feature an internal data storage, that allows storing a major amount of the collected data. In order to maintain the predetermined accuracy of those cable length meters, we recommend a regularly performed recalibration of those devices. Therefore the information is given in the data sheets of the relevant cable length meters or mentioned in the instruction manual.  If you have questions about the photometers, you can contact us at: UK customers +44(0) 23 809 870 30 / US customers (561) 320-9162 . Our technicians and engineers will be happy to advise you on these and other photometers, and of course, on the other products of our range (regulation and control, scales and balances.).

Some of our cable length meters feature an option for temperature compensation since the temperature indirectly effects the relevant wire. In order to now perform an exact and reliable measurement by means of the cable length meters the temperature needs to be compensated first. That can be performed with a variety of methods. The cable length meters for once feature an integrated temperature compensation. Therefore the temperature is measured by an internal sensor of the cable length meters. Thus the collected temperature will be incorporated into the calculation of length and caliber of the relevant cable. To get the cable length meters adjusted to the temperature, it is necessary to place the device for at least two hours near the wire that needs to be measured. In addition to that, there is also the option to perform an external temperature compensation, which is performed via a quadrature loop. The third option is to set the temperature compensation manually. Therefore the surrounding temperature of the wire is set by the user. The feed-in can be set in 1 °C steps. 
Difference between a cable meter and an echometer: There are certain point that differ the cable length meters from one another, even if the devices appear the same at first. Both allow measuring the cable length, but the measuring principle is different. The cable meter must be connected with both ends of the lines first, before the measurement is performed. The advantage of using cable meters is that it can be also used for single-wired cables. The echometer is only connected to one end of the cable, but it the cable needs to be at least double-wired.
