1. Is the power supply normal?
Cause of the problem:
The core circuit of the DC meter requires stable power supply support. If the power supply voltage fluctuates too much or the power supply is unstable, the meter may display abnormally or even fail to work properly.
Troubleshooting and solution:
Check the power input voltage:
Use a multimeter to measure whether the input power is within the working range specified on the meter nameplate (such as 5V, 12V, etc.).
Eliminate contact problems:
Check whether the power plug and cable are firmly connected. If there is poor contact, repair or replace it in time.
External power adapter:
If the meter supports external power supply, please give priority to high-quality power adapters to ensure stable power output.

YTL technical advantages:
The electronic energy metering products we produce adopt low-power design and can maintain stable operation when the power supply fluctuates. At the same time, the overload protection function designed by the R&D team can effectively prevent equipment damage caused by abnormal power supply.

2. Are the ambient temperature and humidity up to standard?
Causes of the problem:
High or low temperature:
High temperature may cause the internal components of the meter to overheat and reduce the service life; low temperature may cause electronic components to fail or inaccurate readings.
Excessive humidity:
When exposed to high humidity for a long time, condensation may occur inside the meter, causing short circuits or abnormal display.

Troubleshooting and solutions:
Check environmental conditions:
Confirm that the ambient temperature is between -10°C and 50°C and the relative humidity does not exceed 85% (no condensation).
Add protective measures:
In environments with high humidity, add a moisture-proof protective cover to the meter or add a dehumidifier to the installation area.
Avoid direct sunlight:
Long-term exposure to sunlight may cause the device to overheat, and it should be avoided to be installed in direct sunlight areas.

YTL technical advantages:
YTL's designed DC meters have a wide operating temperature and humidity adaptation range. At the same time, we have developed a moisture-proof design that is particularly suitable for applications under high humidity and climate conditions. These features make our products widely recognized in more than 60 countries at home and abroad.

3. Is there strong electromagnetic interference?
Cause of the problem:
Source of electromagnetic interference:
Industrial sites often have high-frequency interference sources such as inverters, electric welding machines, and wireless communication equipment, which may interfere with the operation of the meter through power lines or spatial coupling.
Electrostatic discharge:
Electrostatic discharge (ESD) can cause damage to the internal circuit of the meter or temporary display abnormalities.

Troubleshooting and solutions:
Keep away from interference sources:
Install the meter in an area away from high-frequency equipment, or add a shielding layer when wiring.
Add filtering device:
Install an electromagnetic interference filter on the power supply line to prevent interference signals from affecting the meter through the power line.
Electrostatic protection:
Ensure that during installation and operation, personnel and the environment are effectively treated with electrostatic protection.

YTL technical advantages:
Our independently developed DC meter adopts anti-interference design, combined with special circuit shielding technology and precise sampling modules, which can effectively reduce the impact of electromagnetic interference. Our products have been widely used in complex electromagnetic environments in industrial scenarios and have performed well.

In the investigation of external environmental impacts, we not only provide product descriptions, but also customize solutions for customers based on actual scenarios to ensure stable operation of products under various complex conditions.
