Summary of UT203 clamp multimeters “see” even a DC current
The UT203 is an affordable, universal clamp multimeter by UNI-Trend capable of measuring DC and AC current without circuit interruption. It features automatic range selection, a 3999-count display, and measures voltage, resistance, frequency, duty cycle, diode status, and continuity. Using a Hall detector, it detects magnetic fields around wires for non-intrusive current readings in accessible locations like distribution boxes.
Parts used in the UT203 Clamp Multimeter:
- Hall detector
- Automatic range selection system
- Max display reading of 3999
- Voltage measurement ranges (DC/AC)
- Resistance measurement ranges (400 Ohm to 4 MOhm)
- Frequency measurement ranges
- Duty cycle measurement capability
- Diode test function
- Continuity test function
In a very affordable price level, a multimeter able to measure a DC current without interruption of a measured circuit can be found.
UT203 UT203 from company UNI-Trend belongs to a category of clamp multimeters. A main reason to buy a clamp multimeter is usually a requirement to measure current flowing through a wire without its disconnection. A possibility to measure current without (a short-time) disconnection of a circuit is naturally convenient for several reasons – measurement speed, safety point of view and last but not least – in many cases it is impossible or very complicated to switch off a measured circuit and to connect an ammeter into series. Times, when such a device was “only” an Ammeter are a long time away and modern clamp multimeters are literally universal devices, often able to replace common multimeters. A big majority of clamp multimeters is able to measure only an alternate current (AC). More sophisticated devices, to which also UT203 belongs, are able to measure even a direct current (by means of a Hall detector).
As clamp multimeters measure current on the base of magnetic field induced around a lead, it is only possible to measure current of wires, which are accessible separately – for example in distribution boxes, at terminals of devices and similar. In principle it´s also possible to measure current flowing through several wires at once, but it´s necessary to take in mind, that a measured value will respond to a vector summary of currents, thus it will depend on a mutual phase (at AC current) and or on the direction (at DC current) of current in wires.
UT203 represents a modern multimeter with an automatic range selection and a max display reading of 3999. Neither other measuring parameters are not impoverished – voltage can be measured in five or four ranges respectively (DC/AC) and resistance even in six ranges of 400Ohm to 40 MOhm. UT203 also offers measuring of frequency (in 7 ranges), duty cycle, diode test and continuity test (0-50 Ohm). Range selection is automatic with a possibility of a manual selection. Detailed information will provide you the UT203 user guide.
