7.9.4 Single-phase and three-phase testing with the leakage
current clamp
The leakage current clamps BENNINGCM9-1 and CM9-2 are intended for partial testing of
single-phase and three-phase test samples and support the following measurements:
• Protective conductor current (direct current and differential current measuring methods)
ClassI
• Contact current (differential current measuring method) ClassII
There is no connection to the device. The measured leakage/fault current is entered manually
in an input window of the device.
Measuring adapters facilitate testing with the leakage current clamp [}page18].
The test procedures12and13 [}page102] included in the device represent automatic test
procedures for using a leakage current clamp.
When commissioning the leakage current clamp, please observe the supplied operating manual
as well as the instructions for the corresponding individual test.

7.9.5 Barcode scanner (optional)
The optional barcode scanner serves as an optical recognition tool for the device and makes it
easier to manage and identify the test samples. For this purpose, each test sample is provided
with an adhesive barcode label and the barcode scanner is used to scan the barcode and
transfer it to the database of the device. The available barcode scanners can be used via the
Bluetooth
®
or USBinterface.
The barcode scanner converts the scanned barcode into an input– similar to an input made via
the keyboard– and transmits numbers, letters and special characters depending on the
corresponding configuration.
The barcode scanners are configured by default for being used with the device.
The following barcode scanners are optionally available:
• USBbarcode scanner
• Cordless barcode scanner (available from device software ≥1.05 or higher) with two
operating modes
– Cordless operation (integrated in the barcode reader, supports the Bluetooth
®
function
integrated in the device)
– 2.4GHz wireless transmission (supplied USBdongle is required)
