2. How to set up the digital panel meter nha-shunt-a-r3nn
The specific settings of the digital panel meter nha-shunt-a-r3nn need to refer to the official manual, but can be operated according to the general process of the digital display meter. The operation process is as follows:
1. After entering the settings interface and powering on, long press the "Settings" button on the device for about 2 s

2. Parameter Setting Options Overvoltage/Undervoltage Values: Use the directional keys to select the "Voltage Alarm Threshold" option and set the upper limit (overvoltage) and lower limit (undervoltage).
. For example, if a 220V system needs to be monitored, an overvoltage of 242V (10% margin) and an undervoltage of 198V can be set, and an audible and visual alarm can be triggered when the range is exceeded. Select the "current alarm threshold" for overcurrent value and set it according to the specifications of the external shunt. For example, if the shunt is "FL 100" (100A/75mV), the overcurrent value can be set to 100A, and a warning will be triggered when exceeded. The direction of energy accumulation can be selected based on actual needs, either "forward accumulation" (only counting forward power) or "absolute value accumulation" (counting total power, including reverse). The alarm output mode can be selected as "pulse signal" (short triggering), "continuous signal" (alarm continues until the fault is resolved), or "latch release" (requires manual reset). For example, when remote monitoring is required, pulse signals can be used in conjunction with counters. Input the model or specification of the external shunt (such as "FL 050" corresponding to 50A/75mV) to ensure the accuracy of current measurement. If the specifications of the splitter do not match, it
