Page 24: Configuring The Network
Configuring the Network The TWC has an Ethernet socket which allows you to connect it to a network for printing to network printers. When setting up printers an Internet connection via this network is also necessary. The TWC is configured to automatically seek the correct network connection settings via DHCP; when you plug the network cable into the TWC, it will immediately request these settings. - Page 25 Now Click Network Configuration to open the network configuration panel. The panel will show the current network state. You should see something like the below if a network cable is connected. Ensure the Wired connection is selected, as shown here, and press the settings icon in the bottom right to open the network settings panel.
- Page 26 Under the IPv4 tab, change the “Addresses” drop-down setting from “Automatic (DHCP)” to “Manual” as shown here, then type in your desired settings using the USB keyboard: For most networks you are unlikely to need to change any other settings in this window than enter the IPv4 Address, Netmask, Gateway and DNS.

Page 27: Printer Setup
Printer Setup The TWC supports printing directly to a printer attached via either USB or remotely via Ethernet. Alternatively, if no printer is available, documents can be “printed” as PDF files. NOTE: To add a printer you will need to connect a USB keyboard to the TWC. Network connectivity is required to allow the TWC to search for and attempt to download driver packages for printers when setting up. - Page 28 In the window that appears, click “Add” to add a printer. Enter your password (default is “NorbarTWC”) to unlock the printer selection screen.
- Page 29 In the left-hand list will appear a USB-attached printer if currently connected. Beneath this, under the Network Printer drop-down menu, network printers will appear as and when the TWC finds them (this may take several seconds). Add a printer by selecting it and clicking “Forward” to follow the on-screen prompts.
- Page 31 Select a driver for the printer (it’s generally best to go with recommended drivers). Press Forward each time when ready to proceed. NOTE: Some printers, for example HP printers, may have special driver packages that add or otherwise enhance compatibility with their printers.
- Page 32 Enter a friendly name for the printer if you wish (otherwise it will select a default name for you). When you click Apply, you will need to enter the system password again (default is “NorbarTWC”). At this point the printer is added and you can print a test page. The printer will appear as an option when printing certificates or declarations of conformance from the TWC UI.

Page 33: Settings
Settings The settings menu lets users customise document headers (like company name, logo and address), change sensitivity of the peak detection algorithm, backup, restore or erase the database or enter calibration data for the TWC and currently attached transducer. NOTE: Before using any transducer to perform jobs on tools with the TWC, you must provide the TWC with information from the calibration certificate. -
Page 34: Database
Database This menu allows the TWC data store to be backed up to, or restored from, a USB memory stick. It also allows the data to be erased. “Data” comprises: Tools and tool templates • Jobs and documents produced from completed jobs •... -

(how many cycles remain until the TWC should be lubricated) and a means to save a debug log in the event of any issues requiring support from Norbar. The first peak sensitivity setting lets you choose how big of a peak must be observed before it’s taken as a legitimate first peak reading. -
Page 36: Loader Calibration
Loader Calibration In order to produce calibration and conformance certificates, the TWC must know about its own calibration state. This is managed here. In this screen you can input calibration data from both the TWC and the currently attached transducer’s calibration certificates. You will need to do this for every transducer you plug into the TWC, but you only need to do this once (at least, until recalibration is required). -
Page 37: How To Fill In Loader Calibration Page
How to Fill in Loader Calibration Page The TWC has two main calibration states: “system” calibration and “instrument” calibration. A “system” calibration is where the TWC and the transducer have been calibrated as a matched pair (a “system”). In this case, we do not need any data from a TWC calibration certificate as it is all provided by the transducer certificate. -
Page 38: How To Fill In Uncertainty Data
How to Fill in Uncertainty Data Refer to the final page of your TWC/transducer calibration; the page should be titled “Expression of Uncertainties” For Transducers: On the “Expression of Uncertainties” page, you should see a table like the following (shown here, an example for a 400 N·m transducer): Expanded uncertainty k=2.0 Uncertainty interval k=2.0... -
Page 39: Certificate Settings
Certificate Settings This menu lets you configure the content of the calibration and conformance documents produced by the TWC. You can change the company address, the logo, and customise the certificate numbering scheme. Next Calibration / Next Conformance number: for traceability, each calibration or conformance document is numbered, with the number increasing every time one is produced. - Page 40 Company logo; this lets you change the logo from the default Norbar logo to one of your choosing. To do this, you must first place an image of your logo in the necessary folder: ~/.twc_logo To do this: Attach a USB keyboard to the TWC (and optionally, a mouse) •...
- Page 41 NOTE: Your logo file should ideally not be larger than 400x160px or the document layout may be affected. Use the existing norbarlogo.png file for a good size reference. NOTE: PNG and JPEG formats are supported. PNG is a lossless format which makes it a great choice for storing company logos, and is the recommended choice.
