14.2 2-WIRE RTD LEAD COMPENSATION
This section describes how to remove the error caused by lead resistance in a 2-wire RTD.
Ambient temperature changes will cause some error in the readings; the higher the lead
resistance, the greater the error. When performing this procedure, the leads should be shorted
together as close as possible to the RTD. This step is not necessary when using 3- or 4-wire
RTD's since lead resistance compensation is automatic in the meter. When setting up the
meter, it may be necessary to enable some of the menu items. See Section 9 for further
information.
