Thông tin sản phẩm

Máy đo điện trở tiếp xúc MEGABRAS MPK-253 micro-ohmmeter


Test currents

1 mA - 10 mA - 100 mA - 1 A - 5 A.
Each current may be continuously adjustable from 0 to 100%.

Resistance rangers

0-20 mΩ @ 5 A.
0-600 mΩ @ 5 A.
0-200 mΩ @ 1 A.
0-2000 mΩ @ 100 mA.
0-20 Ω @ 10 mA.
0-200 Ω @ 1 mA.

Test currents

1 mA - 10 mA - 100 mA - 1 A - 10 A.
Each current may be continuously adjustable from 0 to 100%.

Resistance rangers

0-2000 µΩ @ 10 A.
0-20 mΩ @ 10 A.
0-200 mΩ @ 1 A.
0-2000 mΩ @ 100 mA.
0-20 Ω @ 10 mA.
0-200 Ω @ 1 mA.

Resolution

1 µΩ @ 10 A.

Output voltage

Up to 10 Vc.c. (open circuit) @ 1 A.

Measurement Principle

Four-terminal, Kelvin-type.

Basic Accuracy

± 0.2% of reading ± 2 digits.

Advanced features

Digital direct reading of very low resistances in the alphanumerical display, with up to 4½ digits. Very fast and accurate measurements.

Teste current measurement

The current is digitally measured and a bargraph shows the result. The bargraph indication is specially useful when measuring inductive loads, so that the operator can verify easily when the test current has been stabilized.

Serial data output

RS232 @ 4,800 bps. Suitable for data collection in an external serial printer, computer or data-logger.

Enviromental

IP54 with closed lid.

Safety class

Meets the requirements of IEC 61010-1, IEC 61010-1.

Power supply

Rechargeable battery 12 V - 7 Ah or 100 - 240 V~ mains supply.

Built-in battery charger

For 100 - 240 V~ mains supply.

Operating temperature range

-5 °C to +50 °C.

Storage temperature range

-25 °C to +65 °C.

Humidity range

95% UR (non condensing).

Weight

Approx. 8.7 kg (including accessories).

Dimension

378 x 308 x 175 mm.
