Fluke 1529 Chub-E4 - Manual (Page 17)

2 Introduction
The Hart 1529 is a low-cost, high-accuracy, digital thermometer readout de-
signed to be used with 25 and 100
Ω PRTs, thermistors, and thermocouples. Its
unique combination of features makes it suitable for a wide variety of applica-
tions from laboratory measurement to industrial processes. Features of the 1529
include:
• Measures 25Ω and 100Ω PRTs, thermistors, and thermocouples
• Four inputs: two PRT/thermistor and two thermocouple (standard config-
uration)
• Four-wire connection eliminates lead resistance effects in PRTs
• Three-wire measurement mode for three-wire RTDs
• Exclusive patented mini-DWF connectors (U.S. Patent No. 5,964,625)
• Automatic current reversal eliminates thermoelectric EMF errors
• Accuracy: PRTs to 0.006°C, thermistors to 0.002°C, and thermocouples
to 0.3°C
• Typical resolution: PRTs 0.001°C, thermistors 0.0001°C, thermocouples
0.01°C
• Measures four sensors simultaneously with a fast one-second measure-
ment cycle
• Measures one sensor at 10 readings per second (limited accuracy)
• Adjustable moving average for extra precision
• Stores over 8,000 measurements internally
• Accepts ITS-90, PT-100 (ASTM E1137, DIN 43760, or IEC-751), and
Callendar-Van Dusen PRT characterizations
• Accepts Steinhart-Hart R(T) or T(R) and YSI-400 type thermistor charac-
terizations
• Accepts thermocouple types B, E, J, K, N, R, S, T, Au-Pt, and polynomial
specified
• Temperature offsets for improved thermocouple accuracy
• Stores 10 additional sets of probe parameters
• Eight programmable display sets for display probe information, measure-
ment statistical data, or difference between measurements
• Password protection of settings
• Large, LCD, user-configurable, display viewable in bright or dim lighting
• Serial RS-232 and IR interface standard; IEEE-488 GPIB interface op-
tional
• Powered by external AC supply, 12-15V DC source, or internal recharge-
able battery
