Measuring Error Test of GF312V2 Tester Using GF333V2 Standard Meter & GF302D1 Three-Phase Standard Power Supply

 GF302D1 portable three-phase tester acts as our three-phase standard power supply for this experiment.

We utilize the GF333V2 high-accuracy three-phase reference standard meter to verify the measurement error of the GF312V2 on-site portable energy meter calibrator.

Boasting 0.01/0.02 accuracy class, the GF333V2 can measure voltage and current across the full range. It features 2nd to 63rd harmonic analysis, vector diagram and real-time waveform visualization, supplying traceable high-precision power values to establish a reliable calibration benchmark.

Every instrument meets IEC, CNAS and CE certification requirements. Reach out to GFUVE if you require calibration equipment for laboratory testing or field work.

Triple Output AC Current Clamp Combo (BNC / 4mm Banana / 3.5 Audio) Solve Multi-instrument Matching Troubles

 Most conventional single-output current clamps force technicians to purchase extra adapters when switching between oscilloscopes, handheld multimeters and portable data loggers, which raises procurement costs and brings signal attenuation risks caused by loose adapter contacts. GFUVE full-series mini, medium and large jaw integrated current clamp set is equipped with interchangeable triple signal output cables as standard configuration, covering three mainstream industry interfaces to match all your existing test devices without extra accessories. The shielded BNC coaxial cable delivers low-noise high-frequency signal transmission, perfectly capturing fast switching current ripples up to 2MHz for power electronics R&D and cable fault waveform analysis. Standard 4mm shrouded banana plug offers stable connection for field portable multimeters, supporting 1mV/A and 1mA voltage/current dual signal output modes for general load and leakage current measurement. 3.5 audio jack is dedicated to long-term continuous data recording equipment, realizing unattended multi-hour power consumption and harmonic monitoring on production lines and substations. All jaw sizes from φ13 slim probes to φ150 bus clamps share unified triple output circuit design, with nickel alloy and permalloy core optional, 0.1% high precision and ultra-low phase shift guaranteed. The whole combo complies with EN61010 CAT III 600V safety standard and holds UL, CE, CNAS full certifications, supporting live split-core clamping without power cut or circuit disassembly. We support customized matching of output signal ratios and cable lengths according to your oscilloscope, power analyzer and logger model, suitable for university labs, new energy manufacturers and municipal power engineering teams that own multiple types of test instruments.

GF211D Digital Phase Tester Clamp Using Steps & Safety Tips

The GF211D dual current clamps adopt high-permeability magnetic cores to achieve ultra-fine 0.1mA resolution for leakage current inspection. Standard operating steps include preheating the host for 3–5 minutes before clamping to stabilize internal circuit temperature, then clearing residual magnetism by fully opening and closing empty jaws to guarantee zero baseline accuracy. The two clamps cannot be cross-used with other phase meters, as each pair undergoes factory matching calibration to maintain consistent phase measuring precision.

Long-term service precautions cover storage and daily inspection. Do not place clamps under high temperature, condensation or corrosive gas environments for extended periods. If jaw surfaces are stained with conductive particles, avoid abrasive cloth or chemical solvents for cleaning; only soft lint cloth is allowed. When finishing all tests, remove clamps from live wires first before unplugging the clamp cables from the meter, to avoid secondary open-circuit risks of CT loops. The complete set of clamps, voltage leads and main unit is packed in a shockproof storage bag to protect all accessories during frequent on-site transfers between power plants and mining workshops.
