Teardown continued..... |

Thanks for the photos and disassembly tips. I'm am back at the office now after a few days of field work on penguin weighbridges. I've just pulled my Sherlock apart as well. I did have to resort to a Wera 1.5mm Hex-Plus bit to remove the rather tight screws, and long tweezers to "release" the push buttons. I will try to do hacking to drive the OLED from my own circuitry later this week. |

Penguin’s ? I adore Penguin’s :-+ I saw a lot of them whilst deployed to the Faulkland Islands back in 1992. Such cute little characters, but boy did their colonies smell bad, especially as I seriously dislike the smell of fish ! |

Some test results from my Fluke 87 III whilst testing probe P.D. and current flow in the probes short circuit condition…… Semiconductor Junction (Diode) Test Mode P.D. Across probes = 3.295V d.c. (Red probe is positive output) Current flow with probes shorted through Fluke multimeter mA range = 0.950mA Resistance Test Mode P.D. Across probes = 3.295V d.c. (Red probe is positive output) Current flow with probes shorted through Fluke multimeter mA range = 0.950mA Voltage Test Mode P.D. Across probes = 0.000V Current flow with probes shorted through multimeter mA range = 0.000mA As you would expect ! :) The 2mm sockets are connected directly to the probe tips. |

Yep, the whole thing in those reviews about using the banana sockets to power the DUT was a misunderstanding. They are just another connection point for the probes to allow using banana to alligator clip leads if you only want to hold one probe. |
