ENGLISH
Connecting and using the bar code scanner.
Connect the bar code scanner to the rear of the TV 470. An acoustic signal
indicates that the scanner is ready.
In order to read a bar code, aim the scanner at the bar code and press the
scan key. An acoustic signal indicates that the code has been read success-
fully.
Repeat tests are simplified when bar codes are used.
In "Auto" mode, reading a bar code will automatically start a measurement.
All measurement values will be saved along with the bar code. With the
analysis, all measurements as well as the bar code will be saved in the da-
tabase.
With a repeat test, all results are automatically sorted to the DUT. For this
reason, ensure that each bar code is assigned only once.
To start a measurement
In order to start a measurement, press the key with the function "Measure"
or read a bar code in the "Auto" mode. In "Auto" mode, the device starts with
the first measurement.
In manual mode, the measurement choices are displayed.
The "Auto" measurement sequence follows the order given by the directive.
This is dependent on the protection class setting on the device.
Protection class-I:
PE conductor resistance – insulation resistance – leakage current – equiva-
lent leakage current
Protection class-II:
Insulation resistance – leakage current – equivalent leakage current
Protection class-III:
Insulation resistance
When testing devices of protection class-I and II, the measurement
can be stopped after the leakage current measurement by pressing
