Fluke 1529 Chub-E4 User Manual

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
