In the revolutionary 7520, Guildline Instruments have developed the first fully automated and self-calibrating Voltage Divider.

Using an integrated Zener based voltage reference and null-indicator the 7520 is able to provide a self-calibration function to achieve long term, sub-ppm ratio measurements with the voltage ratios 1:1, 10:1, 100:1, 1000:1 & reverse in demanding applications.

A full self-alignment cycle takes only 2 hours and provides high quality, accurate data for up to 140 hours, which allows engineers to operate without disruption, while a touch screen interface allows for all measurements to be easily programmed and fully automated.

The operator can choose to use the 7520 as a “Divider”, taking the voltage from an input reference and generating an output voltage based on 1:1, 1:10, 1:100 and 1:1000 ratios.  This mode is typically used to calibrate a working voltage reference or the voltage measurement capability of a voltage meter or digital multi-meter (DMM).

Alternatively, you can choose to use the 7520 as a “Comparator” to compare two external voltages.  This mode is typically used to calibrate a voltage source including the DC voltage generated by a calibrator. These two modes of operation are easily selected from the main menu.

Chris Riddoch, Evolution Measurement’s Business Development Manager for Metrology Instruments said, “The 7520 is an amazing product borne out of high experience and wide industrial feedback. Guildline have really focussed on what is important to our customers from quality and operational availability standpoints. The power of the measurements, the speed of self-calibration and automation function which is easy to use, are all key factors in why this is a really popular instrument.”
