Un medidor digital de HVAC es una herramienta que se utiliza en sistemas de calefacción, ventilación y aire acondicionado (HVAC) para medir la presión y la temperatura de los refrigerantes y otros fluidos HVAC. Aquí hay una guía general sobre cómo usar un medidor digital de HVAC :
-
Elija el puerto correcto: Los medidores digitales de HVAC tienen un puerto del lado bajo o alto para medir la presión del refrigerante. Asegúrese de elegir el puerto correcto para su medición.
-
Conecte el medidor: conecte el medidor al puerto de su sistema HVAC. Asegúrese de que la conexión sea segura y que no haya fugas.
-
Encienda el medidor: la mayoría de los medidores digitales de HVAC tienen un botón o interruptor de encendido. Enciéndelo y espera a que el indicador se estabilice.
-
Tome la medida: La pantalla digital mostrará la presión y temperatura actuales del refrigerante o fluido en el sistema. Lea los valores y regístrelos si es necesario.
-
Apague el medidor: una vez que haya tomado la medición, apague el medidor y desconéctelo del sistema HVAC.

Escazu Chocolates, a bean-to-bar chocolate shop in Raleigh, North Carolina, sources most of its beans from Latin America. The shop said it has always worked with smaller farmers and paid them three to four times the commodity price of cacao – which essentially sets the minimum wage. The spike in prices has pushed up what Escazu pays those workers as well.

Other cost-cutting measures include offering a smaller hot chocolate size, advertising non-chocolate ice cream toppings and moving to a cheaper location in Raleigh to save on rent.

And like many small businesses in America, Escazu is being hit by President Donald Trump’s tariffs, affecting not just the chocolate, but also aluminum in its packaging.

“The tariffs have hit every single piece of what goes into every single thing,” Tiana Young, co-owner of Escazu, told CNN. “There is no new normal.”

Cheung, who regularly expresses hostility toward reporters on social media platform X, asserted in a Friday night post that, “some reporters have been caught” taking pictures of sensitive information and “eavesdropping on private, closed-door meetings.”

That claim came as news to White House press corps leaders, who are not aware of colleagues being “caught.”

Early in Bill Clinton’s presidency, Clinton aides similarly attempted to bar journalists from the “upper press” area, causing an outcry. That ban was rescinded.

Journalists had normal access to the offices during President Trump’s first term in office. But in his second term, Trump and his aides have taken several steps to stymie news coverage and circumvent traditional media outlets.

Last winter, the administration blocked the Associated Press from attending some White House events, leading to a First Amendment lawsuit that is still working its way through the courts.

The administration has also stopped publishing transcripts of Trump’s remarks; has taken control of daily press pool assignments; and has invited fawning pro-Trump commentators to presidential Q&As.

Some cabinet secretaries have followed Trump’s lead. Last month, Defense Secretary Pete Hegseth implemented severe new restrictions for Pentagon press pass credentialing, leading virtually every major media outlet to reject the rules and give up access to the Pentagon complex.

Members of the White House press corps are now restricted from the press secretary’s office, the latest in a series of Trump administration actions to limit media access.

The new rule says journalists cannot access what’s known as the “Upper Press” office space, where White House press secretary Karoline Leavitt works, “without an appointment.”
This area has been accessible to White House correspondents for decades, supporting a free flow of information between the president and the public.

The White House says the clampdown is due to security concerns.
“This policy will ensure adherence to best practices pertaining to access to sensitive material,” a White House memo asserted on Friday night.

In response, the White House Correspondents’ Association, which represents hundreds of credentialed reporters, said it “unequivocally opposes any effort” to limit journalists from areas that have long been accessible for newsgathering, “including the press secretary’s office.”
“The new restrictions hinder the press corps’ ability to question officials, ensure transparency, and hold the government accountable, to the detriment of the American public,” the association said.

As CNN’s Jeff Zeleny explained, reporters routinely “wait in the hall” by the press secretary’s office and seek information from communications aides. “When there is breaking news, that often happens,” Zeleny said.
Now, “reporters will only have access to a smaller set of offices of junior advisers, junior aides, junior press secretaries,” according to the White House.

Even the joy of Halloween will cost more this year, with less chocolate than in years past.

Expect more packages of tangy gummies, riding off a meteoric high last year. Your kid’s trick-or-treat bag may be filled with a lot of pumpkin-spice-filled-anything. And like last year, cocoa bean industry experts are expecting high price tags to be passed down to consumers.

And with high cocoa prices, every producer from specialty chocolate makers to candy giants are changing up how they sell their treats. For consumers, this could mean less chocolate per package, higher prices and less cocoa content – meaning less chocolate-y chocolate – compared to before.

Overall, candy is 10.8% more expensive this Halloween season than last year, according to an analysis of NielsenIQ data conducted by progressive think tank Groundwork Collaborative and shared first with CNN. That’s nearly quadruple the overall rate of inflation.

In 2024, Halloween candy prices only rose 2.1%, the analysis found.
Halloween spending is no fun-sized matter. Americans shelled out $7.4 billion in Halloween chocolate and candy sales in 2024, a 2.2% increase from 2023, the National Confectioners Association said.
