Solved!

can large usage of memory cause battery drain HP 35

HP Recommended

Hi Everyone , i have never had this problem , a friend of mine  asked me this ?  i told i did not think so and running these large programs may consume battery life ,but i did not think just being stored.   He is using the calculator to convert Lat. and Long. to UTM,SPCS and vice versa, I do not think stored programs would consume battery life. but he said after loading them ,several days the batteries were dead. My ? was how old were the batteries,  So  any one had this issue or problem  with the HP 35s.  My calculator is full, with programs and equation., my is fine   I have two HP33 that are full and i do not have this problem ,so what could cause this.

Hi  Maké, i have never had this problem .All my calculator can not hold anything else. So i know it not from the memory being stored, but he thinks so. I think he is using Dr bill Hazelton SPCS convertions to Lat. and Long. vice versa from  the program suite Closure  1, I will have to ask him about the batteries .  He should know what kind, one of the calculators is new surely he read the book. I will have to get back to you on that battery type. thank for all the info i will see that he get it.

Hi!, @surveying101bil:

 

The programs for HP35S, or Dr. Bill ... https://www.google.com.ar/search?q=Dr+bill+Hazelton+SPCS+convertions+to+Lat.+and+Long.+HP+35S&oq=Dr+... are excelent, but not sure if are best, what COGO Plus PRO, of Jacob Wall ... http://m.sgss.ca/?smallView=1

 

Now, if your friends, use the program's, of Dr. Bill, IMHO not consume, more it loads with batteries, that the least complex programs. 

Kind Regards !.
Have a nice day !.

Hi Maké, I just trying to help him .I would test this on another calculator  myself . I have never had this problem with memory being  the reason for this. Have you ever heard of this before  . thanks again for your wisdom.

Hi !, @surveying101bil:

 

I think that, the problem happens, is for the use, of batteries, that are low, of energy or, bad quality.

Kind Regards !.

Hi Maké I think the same , There could be something wrong that is making this happen ,like a electric short in the calculator or bad connection on the contacts,  but this would be rare, I asked him is this a one time thing are did it happen more than once, he has not answer me back yet. I also told him to run these programs on a emulator and this would not happen,but nock on wood this has never happen to me. because  of the memory . I also  write the date of my installed batteries  date on the back of the calculator on tape. this lets me know when i need to change them. So i will not loose any data.i change them every six months. and these batteries are still strong when i test them. I just wanted to find out if anyone else had reported this. I had already  inform him about Jacob Walls programs the last time i talked to him . That is a good investment  for a calculator and all his programs.I will keep you in touch on this problem.
