AC Multi-Range Current Clamp, 500 A, 3 kHz, BNC Output
AC multi-range current clamp, 6 selectable ranges from 10 A to 500 A AC, BNC output with
0.2 V AC f.s., frequency bandwidth 3 kHz, CAT III 600 V
The 9018-50 is an AC multi-range current clamp with a voltage output of 0.2 V AC full scale across 6 selectable ranges from 10 A to 500 A AC. Sensitivity changes according to the selected range. The clamp operates without an external power supply and is rated for CAT III 600 V environments.
Compared to the 9010-50, the 9018-50 features an extended frequency bandwidth of 3 kHz. It offers improved amplitude accuracy and reduced frequency-dependent deviation across its operating range. Enhanced phase characteristics support more accurate measurement of non-sinusoidal and distorted current waveforms within this bandwidth. The clamp is rated for measurement environments up to CAT III 600 V.
A fixed 3 m cable with BNC connector provides the output signal. The clamp can be integrated into digital multimeters, data acquisition systems or recording instruments with suitable AC voltage inputs.
For HIOKI multimeters featuring clamp input functionality, the optional 9704 BNC adapter enables direct connection. The corresponding clamp range can be selected in the instrument setup, allowing current values to be indicated directly in amperes. When connected to other equipment, the selected voltage range should match the 0.2 V AC full scale output and the input impedance should remain sufficiently high to preserve measurement characteristics.
