BRYMEN BM 239R universal meter / phase spin tester is a compact universal meter with True RMS measurement, innovative VFD (ACV+Hz measurement of inverter outputs) and AutoV (voltage measurement with DCV/ACV auto-differentiation and measurement with variable reduced impedance) functions. Typically, these functions are available on more expensive models. BM239R meters are equipped with a phase sequence tester with a choice of 2 sensitivity levels. Normal sensitivity is designed for typical phase sequence testing in a 3-phase installation. The increased sensitivity test is for checking 3-phase electric motors in a de-energized state. The BM239R features EF-Detection for non-contact voltage detection and measures DC/AC currents up to 10A. Traditionally, BRYMEN meters have a high degree of surge and input overload protection. Special functions: AutoV(LoZ) Automatic detection of either DCV or ACV and measurement of voltages with reduced impedance (increasing with increasing voltage) TKF - Phase spin test with two sensitivity levels: high and normal VFD AC V&Hz - Variable Frequency Drives - voltage and frequency measurement function - on the output of frequency converters (inverters) BeepLit - continuity test with short-circuit signaling acoustically and by LCD backlighting EF-Detection - non-contact AC voltage detection Measurements, ranges: - DC voltage [V]: 60mV/600mV/6V/60V/600V/1kV - AC voltage [V]: 6V/60V/600V/1kV - DC current [A]: 6A/10A - AC current [A]: 6A/10A - resistance [Ω]: 600Ω/6kΩ/60kΩ/600kΩ/6MΩ/60MΩ - capacitance [F]: 2000nF/20µF/200µF/2000µF/10mF - temperature [°C]: -40...400°C Features, functions: - display: LCD 6000 - sampling: 5 times/s - True RMS - REL function (relative value measurement) - diode test - circuit continuity test - Data Hold - range selection: automatic; manual - measurement memory: MIN; MAX; AVERAGE - Auto Power Off - polarity indicator - overrange indicator - low battery voltage indicator - NCV - built-in non-contact AC voltage detector - indication of wrong connection of test leads - standards: CE, EN61010 300V CAT IV, EN61010 600V CAT III, EN61010 1000V CAT II, EN 61326-1 - power supply: 2x 1.5V (AAA) batteries - dimensions: 80x161x50mm - weight: 334g - gross weight: 590g Included: - test leads - batteries - instruction - temperature probe - K thermocouple
