For resistance, youll want to aim for a reference resistor as close to the load resistance as possible. To be more accurate, you may want to take multiple measurements.
For capacitance, youll want to choose a reference resistor that gives you an RC time constant of about 1ms.
# Troubleshooting
### The software interface is greyed out and says "Device Not Detected" (Windows).
First, try the steps outlined here:

If that doesnt solve the problem, open the Device Manager. You should be greeted with a screen like this:

Look for *Labrador*.
**If its under the heading of "libusbK USB Devices"** but has a little yellow triangle on it, then the driver is correctly installed and configured - however there is not enough bandwidth.
Move Labrador to a different USB port that does not share bandwidth with devices that stream constantly (in proper terminology: isochronous/interrupt devices). This includes things like keyboards, mice and speakers.
Some suggestions:
* If youre using a hub, connect your other devices to the hub and give Labrador its own dedicated port.
* Plug your other devices into your USB2.0 ports, and Labrador into the USB3.0 or eSata ports (or vice versa).
* Devices that stream constantly are the most likely to compete with Labrador for bandwidth. If you are forced to share a port with Labrador, share it with something like a USB flash drive or card reader that does not stream constantly.
* If need be, disconnect unneeded USB devices.
Your Labrador board should start working.
**If its under the heading of "Other Devices"**, then the driver is not correctly installed and configured. To configure manually:
* Double click on the device name to open the Properties window.
* Select "Update Driver", from the Driver tab.

* Select "Browse my Computer for Driver Software" (Locate and install driver software manually).
* Select "Let me pick from a list of devices on my computer".
* Then select "libusbK Usb Devices" from the list and the device will connect.

* Note: if you cannot see "libusbK Usb Devices", do not try to be smart and select libusb-win32, libusb0 or anything similar. Instead, re-run the installer and make sure that both driver boxes are ticked and installation completes successfully.
**If the device is not found at all.**
* Ensure youre using a cable that has data lines. Some micro-USB phone charging cables are power-only!
* Remove all wires from your Labrador board. And unplug and re-plug it in, twice if necessary. This will get it out of bootloader mode.
### USB connection issues (Other platforms).
On non-Windows platforms, the Labrador reserves the entire bandwidth of a USB hub in order to ensure it gets a solid connection. Move Labrador to a different USB port that does not share bandwidth with devices that stream constantly (in proper terminology: isochronous/interrupt devices). This includes things like keyboards, mice and speakers.
Some suggestions:
* If youre using a hub, connect your other devices to the hub and give Labrador its own dedicated port.
* Plug your other devices into your USB2.0 ports, and Labrador into the USB3.0 or eSata ports (or vice versa).
* Devices that stream constantly are the most likely to compete with Labrador for bandwidth. If you are forced to share a port with Labrador, share it with something like a USB flash drive or card reader that does not stream constantly.
* If need be, disconnect unneeded USB devices.
Your Labrador board should start working.
Some Mac OSX users have reported driver-related issues that prevent the Software Interface from communicating with the Labrador board. To fix it, install [homebrew](https://brew.sh/) and then run the following two commands from the terminal:
brew update
brew install libusb
After resetting your computer, it should work.
### All other problems.
If youre having any other issues with your board, Im happy to help.
The best thing to do is to post an [issue on the GitHub page](https://github.com/EspoTek/Labrador/issues), that way any solutions will be posted publicly.
The second best thing to do is to send me an email. I can be found at [admin@espotek.com](mailto:admin@espotek.com).
