 If you have a TnT Memory model your menu items will cycle as listed.

• Change Insulation Voltage
• Leakage Test Time
• Audio Option
• Label Options
• Barcode Options

Change Insulation Voltage - All TnT models

Some DUT contain MOV's (metal oxide varistor) or commonly known as spike protection devices. These limit the mains voltage to about 280VAC. If you attempt to perform a 500VDC insulation test on one of these devices you will get a failed result. To fix this problem select the 250V option.

• Press the key to select the 250V option.
• Press the key to select 500V option.

You can also set the unit back to 500V by switching the mains power off and on again. The default insulation voltage is 500V.

Leakage Test Time

The leakage test time is adjustable. You may need to adjust timing in this feature if the DUT has a long power up time or requires special power on procedure. Default time for Leakage Test is 20 seconds. From this menu you can change the test time from 5 seconds to 28800 seconds. Adjusting to any less than 5 seconds will put the test time to infinite. 

• Press the key to increase the test time.
• Press the key to decrease the time.
• Press the key to set the new leakage / power test time.

• Press the key to escape out of the menu. No changes saved.

Audio Option - All TnT models

Enabling the audio option will make the TnT use a sound to indicate a pass or a fail at the end of a test. If the TnT unit has never been altered then the audio beep is disabled.

• Press the key to disable.
• Press the key to enable.

Label Options - Only on Selected Memory Models

Changing the label options changes the way the printer behaves or how the tag is printed. When selecting this option you will be prompted with 3 different options. Enable / Disable, Choosing a label set and modify the due date.

 Enable / Disable
Selecting this option will enable or disable the tag information being sent to the zebra printer. The printer can also be disabled by switching the printer off from the power switch located on the side of the printer. Once the printer is switched back on it will not print out the records that were created while the printer was switched off.

• Press the key to disable.
• Press the key to enable.

Choose Label Set:
If you have more than one logo in the printer’s memory (multiple company logos) this function will allow you to select the various logos. If you have one logo stored in the printer then you only need to choose Label 1. If you choose anything else a blank tag will be created. If you have multiple logos then the next one to choose would be label1 and so on. If you are unsure which one to choose select the Label 0.

• Read the on screen message and then press the key.
• Press the key to increase the label number.
• Press the key to decrease the label number.
• Press the key to select the displayed label number.

Customise Next Test Due Dates
Enabling this feature will allow customise next test due dates when testing equipment. When this feature is disabled (default setting) the next test due date is determined by the test date plus the frequency of test. When enabled a custom date can be set after visual test in TnT +M models.

• Press the key to enable.
• Press the key to disable.

Stop Labels Spooling On Power On
If the printer is spooling tags on power on then it has reverted back to the factory default settings. To stop this choose the F3 key when prompted. The printer must be switched on and have a solid green light. If not, the printer won't receive the command.

• Press the key to enable.
• Press the key to disable.

Barcode Options - Only on Selected Models

Barcode options refers to modifying the auto generate barcode function. The barcode options can be selected in two ways. Either holding F3 down when on the new barcode screen or by the TnT options menu. Both have the same menu options expect when entering barcode options VIA TnT options. These menu options are:

• Set the number of digit for barcodes.
• Set the auto generate barcode number
• Use leading zeros for the auto generate number.
• Search all sites on barcode search (only available from TnT options menu).

 
Search All Sites
Allows the TnT to search all sites listed in the site names section for the given barcode. If this option has not been altered then by default search all site is disabled. When disabled the TnT can only search for barcodes that are in the site selected (Indicated by the site name in new barcode / search barcode screen).

Search all sites is useful disabled and enabled. For example, you may have many items with the same barcode number in different sites. Disabling this feature allow you isolate a particular barcode with ease. If you have a barcode but you are unsure which site it is in then you should enable search all sites.

Be careful when search all sites is enabled. If a barcode is found in another site the site name will change when you return the new barcode screen.

Other Features 

Barcode Printing Function - Only on Selected Memory Models
This utility will print out barcode labels from what is typed on the screen. The idea is to save time by storing these barcodes in a book or collection. From here you can quickly scan a barcode without having to retype the text back into the TnT unit. To access this feature:

• Hold the  key from the new barcode / search barcode screen.

 You will be required to select your printer model. The Wavecom printer has a different print orientation to the Wavecom model. Selecting the wrong printer model will make the tag print incorrectly.

• Press the key if you have a Wavecom or plus model printer.
• Press the key if you have a Wavecom model printer.

 Type the text you want for your barcode. If you go past the end of the screen the text will wrap. A maximum of 32 characters can be entered.

• Press the key to print the barcode.
• Press the key to return back to the new barcode screen.
