Introduction

General

The Platinum Resistance Thermometer (PRT) models 5627A is designed to be
a secondary standard interpolating instrument converting temperature to resis-
tance. The 5627A may also be used as a temperature standard for calibration
of industrial sensors. The PRT is used with a readout device to detect tempera-
ture changes or actual temperature.

Recalibration

Recalibration of the 5627A PRT should be scheduled according to the user's
company Quality Assurance requirements. Normally, a PRT is recalibrated an-
nually. Unless the PRT is used only over a limited range, calibration over the
full range of the PRT is recommended. For information on recalibration, con-
tact an Authorized Service Center for an RMA number and current pricing (see
Section 1.3, Authorized Service Centers).
Depending on the user's Quality Assurance requirements, the PRT drift should
be checked periodically at the Triple Point of Water (TPW). Section 7, Trouble-
shooting, provides information on drift with respect to mechanical shock and
oxidation.
