11.2.3 Clamps C-5A
Clamps C-5A are used to measure AC and DC currents and without breaking the circuit with flow-
ing current. The measuring range is 1400A for DC and 1000A for DC. The output voltage is propor-
tional to the measured current. The clamps have the range of 1000A, with a sensitivity of 1 mV/A, ze-
ro adjustment knob and a LED indicating power supply.
The output signal is conducted by a cable (1.5 m) ended with a pin adapted to the socket on the me-
ter.
The arrow marked on one of the clamps indicates the direction of current flow. It is assumed
that the current flows in the positive direction if it flows from the source to the receiver. This orienta-
tion of clamps is required for the correct measurement of power and constant components.
Overloads
a) direct current (DC): ............................................................................ do 3000 A (continuous mode)
b) alternating current (AC): ..................... up to 1000 A in continuous mode - up to frequency of 1 kHz
c) Limiting the maximum current in continuous operation for frequencies above 1kHz according to
the ratio ..........................................................................................................I
cont.
= 1000 A/f [kHz]
Turning on
In order to activate the clamps, slide the switch to 1 mV/A. Green LED will indicate proper operation.
If after the switching operation, the LED is not lit or goes off during the measurements, replace the
battery supplying the meter.
