Unlike rigid-jaw clamp meters, the flexible coil design allows the probe to be looped around large cables, busbars, or conductor bundles that cannot fit inside conventional clamp jaws, making it well suited to measurements in distribution panels and around large electrical infrastructure.A flexible clamp meter of this type is used to measure current non-invasively — the conductor does not need to be broken or disconnected to make the measurement. The HTFLEX33E supports conductors up to 174 mm in diameter and a 600 mm flexible coil length, which extends its reach to large-conductor applications where standard clamp meters cannot mechanically engage the conductor.ValueTronics International stocks and ships test and measurement equipment from its 20,000 sq ft secure facility at 1675 Cambridge Drive, Elgin, Illinois. Equipment is held, inspected, and processed in-house by our team rather than drop-shipped from third parties, giving our customers a single accountable source for current-condition specifics, accessory verification, and order fulfillment on every transaction.Product Core & Specifications Electrical Specifications Measurement range 3000A ACRMS Output signal (@ 1000ARMS, 50Hz) 85mV AC Output impedance (@ 50Hz) 170Ω ± 20Ω Min allowed load impedance 100kΩ Accuracy (at 25°C) ± 0.5%rdg Maximum frequency 10Hz ÷ 20kHz Position sensitivity ± 2%rdg Temperature coefficient ± 0.005%rdg maximum /°C Measurement category CAT III 1000V, CAT IV 600V Insulation Double insulation Pollution degree 2 according to IEC/EN61010-1 General Specifications Flexible clamp length (double insulation) 600 mm Maximum conductor diameter 174 mm Instrument connection cable length 2m (double insulation) Output connection 2m cables with Hypertac connector Operating temperature -20°C ÷ +80°C Storage temperature -40°C ÷ +90°C Operating humidity 15% ÷ 85%HR, without condense Reference Guidelines Safety IEC/EN61010-1:2001IEC/EN61010-031:2002IEC/EN61010-2-032:2002 Important: Minimum allowed load impedance: 100 kΩ.
