GENERAL INFORMATION
This manual provides information on the use of three digital handheld ther-
mometers. Functional features both common and unique to each model are
described.
All three models are microprocessor based, and provide accurate and
reliable operation. They function with the most popular thermocouples; types
K, J, and T. A variety of features in these projects enhance their versatility,
while simplifying operation.
It is recommended that you read this manual thoroughly, especially the
sections on safety, prior to operating these instruments.
SPECIFICATIONS
THERMOCOUPLE INPUTS: 2 (T1, T2) miniature TC connectors.
Accepts male miniature and subminiature TC connectors.
THERMOCOUPLE TYPES: K, J, T
READOUT: T1, T2, T1-T2, and SCAN (T1, T2, T1-T2).
ACCURACY: (18°C to 28°C ambient, 2 years, excludes thermocouple error).
REPEATABILITY: ±0.2°C typical for 1 week at constant ambient temperature.
TEMPERATURE COEFFICIENT: 18°C to 28°C; included in accuracy specification.
From 0°C to 18°C, and 28°C to 50°C; less than ±(0.02% rdg + 0.1°C)/°C.
ENVIRONMENTAL LIMITS FOR OPERATING: 0°C to 50°C, less than 80% relative
humidity (R.H.) up to 35°C; reduce R.H. limit by 3%/°C from 35°C to 50°C.
ENVIRONMENTAL LIMITS FOR STORAGE: –35°C to 60°C, less than 90% relative
humidity (R.H.) up to 35°C; reduce R.H. limit by 3%/°C from 35°C to 60°C.
INPUT CURRENT: 50 nA typical.
READING RATE: (T1, T2, T1-T2); 1 reading/second typical, all parameters.
TC Extended Temp.
