12.6 Transmitting induction “clamp”
(extra accessory for “non-contact” connection)
12.6.1 In case of several nearby utilities for specially
efficient current inducing specifically into one of them or
for “non-contact” connection to the utility under voltage
it is recommended to use transmitting induction “clamp”
CI-117.
12.6.2 In case if “clamp” is connected to the “OUTPUT”
connector the device is ready for operation at this load type.
The internal transmitting inductor «In» is disconnected
(the indicator of «ANTENNA» mode «
» does not glow.
12.6.2 The device operation with transmitting “clamp” is similar to operation with “clips” (“output
cable” with “alligator” connectors). As a result signal voltage across the “clamp” is indicated «U,V»
/ along with signal current in the “clamp” (not in the utility) «I,A» / capacity absorbed by the “clamp”
«Р,W» / impedance of the “clamp” (not the utility) at present frequency «R,
Ω
/k
Ω
». The current
absorbed by the “clamp” is inversely related to the signal frequency at its constant voltage.
12.6.3 If the identification of the “chosen” utility in the “bunch” is required it is necessary to
earth all output ends of the “bunch”.
12.6.4 Then the “chosen” utility should be wrapped around with a “clamp”.
12.6.5 The press of the START / STOP «
» button is initiating the automatic adjustment.
Upon the completion (or interruption by pressing START / STOP «
» button) of the automatic
adjustment process the manual control over the voltage in the “clamp” is possible (as well as over
current, power) by pushing LESS / MORE « » buttons.
12.6.6 After that the utility locating of the “singled out” utility is possible and its identification
in the “bunch” with the use of any proper receiver equipped with electromagnetic sensor (for
locating) or receiving “clamp” (for identification by “sequential search” of the output ends of the
bunch based on the maximum level of the received signal).
12.6.7 The pulse mode «Pu» provides the high intelligibility in spite of industrial interferences
and therefore is recommended to be used with transmitting “clamp”.
12.7 External power sources
To the EXTERNAL SUPPLY connector on the back panel can be connected an “appropriate”
power source currently possessed by the customer.
