This instrument is a 4½ digit, compact-sized portable digital thermometer designed to use external 100W Platinum RTD as temperature sensor. Tem- perature indication follows Reference Temperature/Resistance Tables (Pt385 for European Curve, Alpha=.00385 and Pt3926 for American Curve, Al- pha=.003926). SAFETY INFORMATION It is recommended that you read the safety and operation instructions before using the thermometer.
ELECTRICAL Temperature Scale: Celsius or Fahrenheit user-selectable. Measurement Range: Pt385(100W ) -200°C to 800°C, (-328°F to 1472°F) Pt3926(100W ) -200°C to 630°C, (-328°F to 1166°F) Resolution: 0.1°C or 0.2°F Accuracy: Accuracy is specified for operating temperatures over the range of 18°C to 28°C (64°F to 82°F), for 1 year, not including RTD probe error.
