9 891 Before You StartSafety InformationBefore You Start1 The Reference Thermometers (1523, 1524) are designed to be reliable, stable, tem-perature measuring instruments that can be used in the field or laboratory. They offer accuracy, portability, and speed for nearly every field calibration application. The instruments have been designed with the field user in mind and are easy to use while maintaining stability, uniformity, and accuracy comparable to some laboratory instru-ments. Your Fluke 1523 and 1524 thermometers are a handheld, battery operated instrument that measures temperature using Platinum resistance Thermometers (PRT), Thermistors, and Thermocouples (TC). Standard EquipmentUnpack the instrument carefully and inspect it for any damage that may have occurred during shipment. If there is shipping damage, notify the carrier that the following components are present:1523/1524 Reference Thermometer with 3 AA batteries AC Adapter, with power cord RS-232 Cable User s Guide Documentation CD Report of Calibration and calibration label Clamp-on ferrite(s) If all items are not present, contact an Authorized Service Center.
