Ammeter EA2268, EA2268 milliammeter (EA 2268, EA-2268)
Ammeter EA2268, EA2268 milliammeter is designed to measure current in AC circuits power frequency and direct current.
Measuring range - 5mA, 10mA, 25mA, 50mA, 100mA, 200mA, 0.5A, 1.0A, 2.5A, 5.0 A, 5.0 A, 10A.
Class of accuracy - 0.2-0.5.
Technical characteristics of the instrument ammeters EA2268, EA2268 milliammeter:
Instruments used for verification and calibration less accurate instruments, as well as to test the parameters of products in their manufacture, inspection and test.
The main features of the instrument EA2268 ammeter, milliammeter EA2268:
- High accuracy measurements of RMS (TRMS) and alternating current;
- Low internal resistance, ensuring minimal impact on device operation modes of equipment in the circuit which are measured;
- Possibility of extending the measuring range of standard connection of external shunts or current transformers;
- Monitoring the accuracy and efficiency of the device can be performed by the apparatus at a constant current.
EA2268 instrument ammeter, milliammeter EA2268 - analog dual-band direct-action device.Made in the form of direct current magneto-meter system with a moving part on extensions with needle indicator and uniform scale length 150mm, with antiparallaksnym device, and the mean square value of the converter input to DC.
The instrument measures the mean (rms) value of AC, AC DC and DC.
Readings do not depend on the shape of the curve of the measured signal.
Instruments EA2268 ammeter, milliammeter EA2268 may be used instead of similar purpose devices such as E5hhh, D5hhh.
