RE: Question about HP-41CV/CX battery terminals
When I repeated the above tests wih an hP-67 and HP-45 I got the same readings of ZERO when their physical switches were OFF. When I turned the switches to ON, my multimeter registered a value!!! Bingo!!
My comclusion is that the HP-41C/CV/CX have "digital" switches that need batteries to be activated!!! In OFF mode the battery terminals look like they have a short!!! Also, my multimeter reads zeros ohms when the leads are apart. So it treats zero and infinity as the same! The makers were too cheap to put an infinity symbol! Namir |
