Calibrating Line Impedance Testers

The Calibrator's Line Impedance calibration function calibrates the line impedance
function of loop testers and multifunction installation testers with loop testing capability.
Different models of installation testers use different test current levels to avoid tripping
protective circuits. The Calibrator limits the amount of test current that can be used
during a line impedance calibration.
To avoid electric shock, do not touch the L, PE, or N terminals
on the Calibrator or UUT while performing a Line Impedance
calibration. Line voltage is present on these leads during this
calibration.
To perform a Line Impedance calibration:
