The programmable temperature offset feature allows the operator to shift the displayed temperature reading. The displayed temperature reading the sum of the voltage drops around the loop. Typically a 30 VDC can be offset either positive or negative to the actual measured temperature.
Programming a negative number for the offset value decreases the display value. ALARMS Optional : displayed value by10 throughout the entire range, or programming for the Solid State: Two, isolated, sinking open collector NPN transistors acting in offset value will decrease the display value by 10 throughout the entire range.
Six of these terminals are for the two Form-C relays and the other Relay Life Expectancy: , cycles at max. As load level three are for two open collector transistors, which act in parallel with the relays.
The two alarms are completely independent with programmable values, hysteresis deadband , high or low acting, auto or manual reset, triggering from If the alarms 4 to 20 mA: Digital scaling and offsetting within 4 to 20 mA range are programmed to latch manual reset , then they can be reset either by the Accuracy: 0. Resolution: 12 bits This is useful in alarm set-ups where a pre-warning control activates before a Min.
Load Resistance: 10 KW 1 mA max. Changing the shut-off trip value alarm 2 automatically changes the pre-warn value alarm Alarm and hysteresis values can be modified through the Peak and Valley recording. Programmable temperature offset and slope. The indicator responds The re-transmitted analog output option transmits a digitally programmable to a host of commands, including change alarm value, reset totalizer and transmit temp input signal.
Two loops are required for all hook-ups; a transmit 4 to 20 mA current to drive chart recorders, remote indicators and controllers. Since the indicator The compliance is 10 VDC.
A built-in 20 mA source is provided in the transmit loop. When GPIO pins are configured to an input state, they are often used to read sensors or external signals. Atmel T89C51CC Please select which document to open. The big question after reading that documentation page is: how do I initialise the UART, and how do I implement the putchar function, on an Xmega?
Because the example code on that webpage is geared towards the non-xmega parts. I'm not going to hold your hand through this, it's really straightforward. First, the Hardware. This one's a bit of a kludge but it does work. Pulse Width Modulation PWM is a technique widely used in modern switching circuit to control the amount of power given to the electrical device. Each example has full source code with documentation, and also readymade binaries to get started quickly.
Atmel recently launched an online tool which allows you to create and configure a template solution for a given set of hardware. Our tutorial on using AVR Studio 5 with Arduino has been around for almost a year now, and we thought it was time to bring it up to date.
This is a pdf version of a website. This tutorial is meant for beginners in the field of Atmel AVR programming. Atmel Classic Microcontrollers with Flash Memories, standard sizes and pin-outs, suitable for replacing many similiar brands. Atmel Studio 7 is free of charge and is integrated with Advanced Software Framework ASF a large library of free source code with 1, project examples. Just add comms on top.
Memory map of Atmegap is also added. I "think" I understand the programming semantics involved, but what I thought I understand is not consistent with the example before me.
For example, if you type the first few letters of include, e. Starting from either a new project or an example project, Atmel START allows you to select and configure software components from ASF4 and AVR Code , such as drivers and middleware to tailor your embedded application in a usable and optimized manner.
Five interchangeable tips facilitate access regardless of tight fits and difficult locations. The FreeHand probe holder brings added versatility, allowing several probes to be used at the same time on a variety of test points while maintaining the short paths needed to preserve signal fidelity. This unique capability eliminates the need to manually apply plastic rings or colored tape to determine which channel the probe is connected to.
The PP accommodates a wide range of applications, including probing of analog and digital ICs commonly found in computer, communications, data storage, and other high-speed designs. The probe's input impedance remains nearly constant over its entire frequency range.
Robust to over voltage and ESD exposure, it is particularly useful in applications producing fast rising, narrow pulses with amplitudes, which exceed the dynamic range of active probes. With the ProBus interface, the AP and AP become an integral part of the oscilloscope, allowing sensitivity, offset and common-mode range to be displayed on the scope screen.
Common mode sensing and input protection capabilities of the AP add additional functionality. Nondestruct Voltage 1. All fixed-attenuation, standard probes automatically rescale compatible LeCroy oscilloscopes for the appropriate attenuation of the probe.
Probe Kit: trimming tool, and ground lead with a crocodile clip. The differential techniques employed permit measurements to be taken at two points in a circuit without reference to the ground, allowing the oscilloscope to be safely grounded without the use of opto-isolators or isolating transformers. The ADP is designed for troubleshooting low-frequency power devices and other circuits where the reference potential is elevated from the ground or the location of the ground is unknown.
The ADP is designed for measuring the high-speed floating voltages found in today's power electronics. Based on a combination of Hall effect and transformer technology, LeCroy current probes are ideal for making accurate AC, DC, and impulse current measurements. Fully Integrated with Oscilloscope Many current probes require external power supplies or amplifiers to display a waveform on the oscilloscope screen.
Along with providing power, the ProBus connection allows the current probe and oscilloscope to communicate, resulting in current waveforms automatically displayed on screen in Amps, and calculated power traces scaled correctly in Watts.
This full integration also allows for Degauss and Autozero functions to be done directly from the oscilloscope with a single button press. Applications LeCroy current probes are available in a wide range of models for a wide range of applications.
Multiple current probes can be used together to make measurements on three-phase systems, or a single current probe can be used with a voltage probe to make accurate instantaneous power measurements. LeCroy current probes are often used in applications such as the design and test of switching power supplies, motor drives, electric vehicles, and uninterruptible power supplies. The CP features a small form factor making it easier to probe on a crowded, compact board.
The small jaw can probe currents in tight spaces and still clamp onto conductors up to 5 mm in diameter. Continuous currents of 30 A rms and peak currents of 50 A can be measured by the CP, which also features a 50 MHz bandwidth. This probe also features an overheating protection circuit, which will display an on-screen warning to the user to prevent damage. PLD Design Resources.
