By flashing, the LED on the front panel makes it possible toobserve whether the

measuring is active or not.

The LCD display on the front panel makes easy and accurate power reading possible.
Note: User can not reset index. If the value of index exceed 999999.9, it is resetted
automatically and continue to count.

Watt-Hour Meter with LCD

In today's world, Efficient Power Management is very important for low-cost. Measuring process must
have been fulfilled with certain accuracy for precise analysing and measuring the energy.
ES-32LS measures the active watt hour consumption directly and error free in single phase systems
and it shows the total watt hour consumption.
The most important features of the device are its reliability, small size, light weight, modern design, and
easy installation.

Communication

This device has RS-485 communication infstructure for remote monitoring.

At first start, device displays the screen located below for 1 second. Here;

read and written at the ModBus registers address.
