Correct, 5.06 is the new version. Thought about getting a programmer, but maybe later on. |

My modules are not .156 spaced, they are .150 spaced. (or so I've measured several times) |

The TL866 type programmer works great, but couldn't cope with the high voltage chips... the chips ended up with "weak bits" that caused unpredictable behaviour in the controller. Took me a while to figure that one out, as you can imagine! :D |

Somebody should explain those extra connections of P12 and P13. In place somewhere else? My DC Sgn Cond has a clear hole and metal edge of half of 4th pair of P12. Current Shunts has also a metal edge but AC RMS has not, AC RMS also has a slim 3rd connection of P13. Ohms has no hole nor metal edge or extra P13 stuff. Current Shunts has also some metal case close calls. Should I move or insulate it? |

Today i got an image similar to the first post of this thread. We have two meters HP 3478A and a Keithley 2700, acquired some days ago. Both never calibrated by us. Image shows todays check/comparison measuring a 2x5 LM399 array i made some months ago. - The 3478A with green DIY backlight - The 2700 delivered a "Benchkit 2000" to a Keithley 2182A Regards, Dieter |
