Fluke 52 K J Thermometer
FUNCTIONAL OVERVIEW The Fluke 51 and 52 K/J Thermometers take nonlinear voltages from thermocouples and convert the voltages to meaningful temperature readings. These thermometers are actually microvoltmeters with additional features to compensate forthe reference junction and non-linearities of thermocouples. The heart of these instruments is an analog-to-digital Converter (a/d converter) that develops a numerical representation of an analog voltage. The a/d Converter (UI) works in the range of -10 mV to +55 mV. Sony nex 5t user manual pdf. Panasonic telephone kx ts3282b user manual. For the Fluke 52, three signals must be measured: thermocouple I, thermocouple 2, and the signal that represents the temperature of the reference junctions. To measure the three signals, the a/d Converter is connected to each of these signals one at a time. A microcomputer (U2) coordinates the switching and a/d activity performed by U1. U2 also interprets the numbers sent by the a/d converter, including reference junction compensation, linearization, and degrees Celsius and Fahrenheit conversion. U2 also monitors the instrument control buttons and drives the liquid crystal display (LCD)
Fluke 52 Service Manual
An item that has been used previously. The item may have some signs of cosmetic wear, but is fully operational and functions as intended. This item may be a floor model or store return that has been used. Recommend to a Friend. EXCELLENT AS ALWAYS. I've always wanted a 50 series and decided to go with the 52-2. Great to have dual inputs which eliminates having to move thermo couple when snapping in. The optional hanger/magnetic strap is a must which makes life so much easier.
