• Temptale 4 reset. 4 wheeler clipart july 4 clip art. Test, Measurement & Inspection, Electrical & Test Equipment Extech 445815 Humidity Meter with Alarm.
• When the TempTale4 Probeless Dry Ice monitor is exposed to a temperature outside a pre- Receiving a TempTale 4 Probeless Dry Ice Monitor programmed limit and time threshold, an “Alarm bell” will appear in the lower right corner. Important: Always use protective gloves and caution when removing the TempTale4 of the LCD display.

The TempTale®4 USB (TT4 USB) combines the industry-leading performance and reliability of our traditional TempTale®4 temperature monitor with an enhanced feature set enabling quick and easy shipment dispositions.

Here, market leader, Sensitech have created a state of the art Cold Chain Shipping Trip Temperature Logger in the TempTale 4 USB. The beauty of this device is that it analyses temperature fluctuations over the duration of shipment by simply inserting into the USB port of an everyday PC without the need for proprietory software. The parameters of the device are set to the requirements of the customer before it leaves the factory. For example - the duration of the trip, the acceptable low/high range of temperature tolerances during the trip; eg +2 to +8 Deg C, whether the alarm needs to be audible or just an icon on the LCD display, how soon the alarm needs to display once the temperature has gone out of tolerance etc. You Specify and the TempTale 4 Complies!

The data from the TempTale 4 USB can be universally analysed at disparate receiving sites and understood in the common language of Adobe PDF format. Critical Data can be then e-mailed to interested parties worldwide. An ideal application for this device would be transportation of Clinical Trials Materials. Please Click on the PDF for more information or Send us an e-mail enquiry so we can discuss your needs and customise a TempTale 4 USB or related device to them. Price shown excludes VAT & Delivery.

I'd expect any 'reset' procedure to happen through the USB connector with some proprietary software which would tell the device to wipe its storage memory (the 24C64) and initialise itself again, wouldn't make sense to expect a shipper/logistics department to open up a device and whip a PIC programmer to get it on to the next job.

I recently got my hands on a DeltaTRAK temperature logger. This type of device is normally used to ensure the temperature of sensitive materials stays within a certain range during transport. As I understand it, they are designed to be used once and then reset by the company. I used it to track the temperature of my luggage during a flight and now I'd like to play around with resetting it. I dont know much about microcontrollers but I'd like to use this as an opportunity to learn. I cracked it open, one screw.

The most interesting part seems to be the six points along the top labelled: MCR, PVD, GND, PGD, PGC, and PGM. My research points to MCR referring to a reset of some kind. PVD may be some programming voltage. GND needs no introduction. PGD, PGC, and PGM seem to be part of some PIC microcontroller programming system.

Heres a closer shot of the mc Its a PIC18F14K50 8-bit microcontroller. The other chip on the board is a FM24C64A. Not sure what it is. I have tried shorting MCR to GND, it didnt seem to do anything. Do I need to buy some programmer to play with this? I recently got my hands on a DeltaTRAK temperature logger.

I have tried shorting MCR to GND, it didnt seem to do anything. Do I need to buy some programmer to play with this? Ah, if that one is meant to be single use then it likely doesn't have the required routines to start fresh.

Best bet I would say would be to poke at the 24C64, read it as backup, try to erase it, if unsuccessful try to figure out the contents and see if something could be used to store a state separately from the data. But then the state could also be stored in the PIC's internal EEPROM, which you might be able to read or not again based on the read protect configuration bit. So basically your investigation toolset should include a PIC programmer and a serial EEPROM programmer. And no guarantees you can do anything with it in the end (besides rewriting a firmware from scratch, that's of course always possible). Note that there is an 'RST' test pad on the board, could be interesting to see where that trace goes.

Yep, it is very probably that is code protected. But you can always code your own firmware, by reverse engineering the circuit. The data must be in the eeprom.

Its a 64kbit/8kB eeprom, so it can record lots of data. They say in the website 3823 points.

I assume they only need one byte, because the range of the reading are from -40F to 149F, so it can even be able to record even more Data. Erasing the EEPROM canno't solve your problem, because the pointer to the next address is probably in the microcontroller. Since the PIC only has 256Bytes of EEPROM i dought that the data are getting stored there, but that pic can also use ROM space to save readings, but i don't think so. Reverse-engineering such product to learn programming is pointless IMHO. It is doable but that is just too many challenges.

Get some decent eval instead if you want to learn embedded. This miserable PIC8 has 8k of program words and tiny SRAM. With crippled XC8 compiler you won't be able to fit anything more than USB stack inside.

So in this case PICKit3 won't help much - you need an XC8 license or USB stack ported to SDCC (not a task for noobs). There are bigger user-friendly USB PICs available (some PIC32MX or perhaps even PIC18F4550 which works with PICKit2 if you cannot afford PICKit3).
