Cables
To reduce the possibility of inducing errors with ac signals picked up by the test
leads, use short, shielded twisted-pair PTFE-insulated test cables between the test
equipment and the Meter. Fluke makes a 2 foot (PN 738716) and 4 foot (PN
738724) PTFE insulated test cable for this purpose
[1] Other alternate standards beside those listed can be used as long as they provide sufficient traceable [Test
uncertainty Ratios (TURs)] at each calibration and verification point.
