RCD Ramp Test:

Set RCD Type

Start Exit

Caution: Pressing F3 at the RCD ramp test screen will cause tripping if RCD fitted to circuit. F2 can be

pressed to change the RCD type at this point. See "Changing the RCD type" for details.

The Trip Current Test will ramp the mA current up until the RCD breaker trips. Current range 2.55 -

500mA. This test can go for up to 10 sec to scroll through full range if RCD faulty or not fitted. Repeated

testing in this mode will cause heating of TnT. Should over heating occur the internal temperature sensor will

cause display to indicate “over temp allow to cool” This requires the TnT device to be best left unplugged for

several minutes allowing unit to cool.

TnT will display results for 5 seconds after mains supply is tripped. If the power is not reset by the time the

unit loses power then the result will be displayed on power on.

Caution: Continuous ramp current testing will cause unit to over heat

TnT +M, +XM - Memory Operation

Introduction

The TnT Memory model has inbuilt flash memory and real time clock. This gives the ability to store up to 5000

records, which can include items from 16 different sites and 6 different users. This will help to increase the

efficiency and pace of testing. The TnT memory unit has two operating modes:

Standard TnT tester (Non-memory)

Test and Tag (memory)

The TnT mode is determined if a keyboard is connected. If there is no keypad detected then the TnT will load

the main menu screen and function as a standard unit. If the keypad is present then the new barcode screen

will be loaded.

Powering on the Tester

When the tester is powered on the scanner will beep a few times indicating the scanner is also powered. If no

beep is heard check the PS2 connections from the tester.

If the TnT tester gets stuck on the logo screen please check the connectivity of the keypad / scanner cable.

The TnT unit will not work if only the scanner is plugged in. If you are using the scanner you need the keypad

plugged in as well. Not having a scanner and just the keypad works too.

Initially the printer‟s status light will be orange but after about 5-10 seconds it will change to green. The tester

will not print unless the printer light is solid green. A flashing red status light can indicate a media or general

printer fault.
