An identification of the calibration method eg. HC family is a good all-round choice, will work at datashheet as well as 5V, good output drive, fast, low power, cheap If the detected deviation is too large in relation to factory specification, adjustment of your data logger or measuring instrument will be required.

MarkT Brattain Member Posts: Email Required, but never shown. Using multiple instances of the BME class associated with each selected output will allow proper tracking of any internal state and data associated with the device connected to that output. LS is Low-powered shottky.

Can I get my instruments re-calibrated and is it necessary? This additional time for the calibration should be taken into consideration to your normal delivery time. An error occurred login failed. The measurement error is documented on a calibration certificate, which serves as proof. Serial output always says Unable to find BME Currently their gates are connected directly to the pins of the ‘s and other posts here etc.

After calibration is performed, you will receive an ISO certificate from Intertek, which is valid for 12 months. Post as a guest Name.

Formal verification of safety-critical software, software development, and electronic design and prototyping.


The only time it would make sense would be if you were wanting to connect with 5 or more devices, in which case 74hc183n would get a saving in the number of pins used. Thanks to my pal Majenko, I’m out of the 74HC stock but i have 74HC, i think that’s same to me, i tried advice from Majenko early morning after i make assembly of my board own for define Chip Select Wemos to my enable pin and get back my missing code whom not understand me. After the order has been placed for the calibrated version, the non-calibrated device will be sent out from our warehouse to the calibration institute of Intertek 74hc38n service in process at Intertek Creating the certificate for end user The device will be repacked and sent directly to the end user.

See below for serial monitor. Please enter your name and your e-mail address. Usually the time for the calibration of your device can be handled within 5 working days.

Or, and this is just throwing ideas out there, don’t use the 74HC and tell your “lecturer” that it’s a stupid idea to use 3 pins 4 including the chip select pin to control a pair of devices that need a total of 2 pins.

74HC138N Datasheet

But yes, specific LED driving buffer chips would be far better. You will find two items appearing, datssheet version without a calibration service item-nr. You don’t connect it dataxheet ground. As the product is customised to your requirements, we cannot accept returns should you decide you no longer want the instrument. I believe that ‘ style encoders only have 1 pin true at a time, meaning you’ll need to continually scan the Leds, You might be better off using 8-bit latches instead.


I think something is missing my code. Please visit our website to find instruments which can be calibrated.

Your message has been sent. The Intertek calibration service provides the assurance that your instruments perform as stated in the datasheet. That’s wasting one more pin than you would by directly driving the CS pins. Country of origin United States US.

I 74hc1138n it’s because CS pin cannot detect.

Looks the same to me. This is my code: All orders for calibrated items are non-cancellable and non-returnable. OK, quick family survey: Now with Unlimited Eagle board sizes! What do I receive 74hf138n I choose a calibrated product at Distrelec?

Using a 74HC in this situation is both pointless and wasteful. The price for the calibration service is already included in the final price for calibrated version.
