Chinese user manual for the Hongrun OHR-D13 Series single-phase LED display power transmitter: specs, safety, panel, and parameter settings.
This is the Chinese user manual for the Hongrun OHR-D13 Series single-phase LED display intelligent power transmitter. According to the introduction, the unit uses a low-power microprocessor with a five-digit LED display and alarm indicators, measures voltage, current, active and reactive power, power factor, frequency and energy on single-phase lines, and can transmit data through RS485/RS232 or analog output.
The manual covers the technical parameters, safety notices and the installation and startup flow, the front panel symbols, keys and error codes, and the parameter setting menus (system, input, communication, alarm, decimal point and analog output settings). It also includes ordering notes describing selectable extended functions. This manual is written in Chinese.

It uses a switching power supply of AC/DC 100 to 240 V, 50/60 Hz.
It provides RS485/RS232 communication interfaces with a settable baud rate of 1200 to 9600 bps and uses the MODBUS RTU protocol.
It is mounted on a 35 mm DIN rail.
ERR-1 indicates an internal parameter self-check error.
Yes, if there is no operation for 10 minutes the system automatically returns to the initial screen.
