Quality Assurance requirements. Normally, an SPRT is recalibrated annually. Unless the SPRT is used only over a limited range, calibration over the full range of the SPRT (–200°C to 480°C for the 5680 and 5682, and –200°C to 661°C for the 5699) is recommended. For information on recalibrating your SPRT, contact a Hart Scientific Authorized Service Center (see Section 1.3) for calibration options, an RMA number, and current pricing. - Page 10 Whether the thermometer is returned for repair or warranty, please include a letter containing the following information • Description of the faulty operation and circumstances of failure. • Complete shipping instructions for the return of the thermometer to the customer.

Lead Wire Identification The Model 5680/5682/5699 SPRTs are equipped with a five-wire cable. Four lead wires are used to cancel lead wire resistance. The fifth wire is a ground wire which is connected to the Inconel sheath. For best results, the readout de- vice should be equipped to handle four-terminal resistors. -

DO use the correct drive current with the thermometer to prevent error in temperature or resistance. DO anneal the thermometer at 480°C for the 5680 and 5682, and at 661°C for the 5699 when it has been subjected to mechanical or temper- ature shock. - Page 16 5680/5682/5689 SPRT User’s Guide Model 5699 only 11. DO anneal the SPRT after delivery or when using at a temperature higher than 600°C. 12. DON’T take the SPRT out directly when it has been at a temperature higher than 500°C. Allow the SPRT to cool to a temperature less than 500°C before removing it to room temperature.
