UNI-T UT203R clamp-on multimeter

Product detailed description

The UT203R digital clamp meter is used for measuring AC and DC voltages up to 600V, AC and DC currents up to 600A and frequency 10Hz to 60kHz for LV voltages up to 600V and 10Hz to 10MHz for MV voltages. On all ranges it has protection against voltages greater than 600V and an audible and optical alarm. Four-digit multi-segment display measuring 37 x 25mm with backlight and fast refresh rate (3 times/s). The non-contact electric field sensing (NCV) allows the detection of live conductors in two sensitivities -EFLo and - EFHi for LV 110V/50/60Hz and 230V/50/60Hz. The included probe - probe tip cover on the test cables allows measurements on CAT III LV distribution lines without arcing hazard. Without the spike covers, the test cables can only be measured on CAT II LV distribution lines. Power supply battery 2pcs 1,5V R03. Power consumption of the meter is approx. 1.8 mA. The circuit has an automatic power saving function. Sleep mode consumption is <11µA, effectively extending battery life to approx. 400 hours. - Measurement of high voltage, current and frequency up to 600 V - Frequency measurement of 10Hz to 10MHz - Capacitance measurement 6nF to 60mF - Proportional (relative) voltage and capacitance measurements - Multi-segment display and audible/visual alarm - Protection against voltages greater than 600V across ranges - Non-contact detection of live conductors - Automatic range switching - Accuracy is guaranteed between 1% and 100% of range TECHNICAL SPECIFICATIONS: - DC voltage: 400.0mV / 4V / 40V / 400V / 600V - Accuracy: ±(0.5%+3) - Input impedance approx. 10MOhm - Overload protection at 600Vrms - AC Voltage: 4V / 40V / 400V / 600V - Accuracy: ±(0.8%+3) - Frequency monitoring accuracy when measuring AC voltage from 10Hz to 60kHz ±(0.5%+2) at 0.01Hz to 0.01kHz resolution - Overload protection at 600Vrms - Input impedance approx. 10MOhm - DC Current: 40A / 400A - Accuracy: ±(2.0%+5) - Overload protection at 420A - AC current: 40A / 400A - accuracy: ±(2.0%+5) - Frequency monitoring accuracy when measuring AC current between 50 and 100Hz is ±(1.0%+5) at 0.1Hz resolution - Overload protection at 420A - Resistance: 400Ohm / 4kOhm / 40kOhm / 400kOhm / 4MOhm / 40MOhm - Accuracy: ±(0.8%+5) - Overload protection at 600 Vrms - Open circuit voltage approx. 1V - Frequency: 10Hz to 10MHz - Accuracy: ±(0.1%+4) - Filling: 0.1 to 99.9% - Accuracy: ±(3.0%+5) - Circuit continuity check: - A buzzer sounds when the measured resistance is less than 10Ohm to indicate a continuous circuit - When the measured resistance is greater than 31Ohm, the signal of a disconnected circuit does not sound the buzzer - Uncertainty between 10Ohm and 31Ohm - Open circuit voltage about 2.0V - Measurement on 600Ohm range - Overload protection at 600 Vrms - Diode measurement: - In the pass direction, the voltage drop across the semiconductor junction is less than or equal to 2V - For a silicon junction, a voltage drop of 0.5 to 0.8V is typical - Open circuit voltage about 4V - Measurement on the 4V range - Non-contact sensing of electric field (NCV): - Allows the detection of live conductors in two sensitivities -EFLo and - EFHi for 110V/50/60Hz and 230V/50/60Hz LV distribution. - Measurement of maximum and minimum values: yes - Measurement in relative (ratio) mode for voltage and capacitance measurements: yes - Data hold (HOLD): yes - Low battery indication: yes - Automatic power off: yes - Power supply: 2x 1.5 V AA batteries (R03) - Backlit display size: 37 mm x 25 mm - Product dimensions: 215 mm x 63 mm x 36 mm - Product net weight: 235 g - Product colour: red and grey PACKAGING CONTENTS: - UT203R clamp multimeter: 1pc - Test Cables: 1 pair - 1.5 V battery (R03): 2pcs - User manual: 1pc
