Характеристики

General
SEM-250D Multimeter are designed to display 3 phase current, voltage and frequency.
Usage and Working Principle
Make the connections according to the diagram. Connect the current transformers before electric charges to be connected to the system. SEM-250D Use the 3 pcs CT-300(10-250 A) current transformers provided with the device. Connect the current transformer lead wires to k-1 terminals of the device. The device automatically displays the current value without any setting. So, don't use current transformers of different brands and models. Wher the device is energized, it shows the phase-neutral, phase-phase voltages, frequency, phase sequence and current values on the displays.
You can see the frequency between phase and phase, phase and neutral at the first display group. When the voltage values is shown (V) led gets on. While pressing the up button ,phase-phase range can be seen.When the phase-phase values is shown you can see the leds on phase – phase. While pressing theup buttons you can see the frequency value and Hz led gets on. Phase Sequence: If the phase sequence is reverse you can see the (X) led gets on which take place in the 1st display group.
Maintenance
Switch off the device and release from connections. Clean the trunk of device with a swab. Don’t use any conductor or chemical might damage the device. Make sure device works after cleaning.

Warnings
Please use the device according to the manual. Don’t use the device in wet. Include a switch and circuit breaker in the assembly. Put the switch and circuit breaker nearby the device, operator can reach easily. Mark the switch and circuit breaker as releasing connection for device.
