Introduction

The Hart 1529 is a low-cost, high-accuracy, digital thermometer readout de-
signed to be used with 25 and 100 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 25 and 100 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 interface standard; IEEE-488 GPIB interface optional
Powered by external AC supply, 12-15V DC source, or internal recharge-
able battery
