Description:
Item type:digital meter
A.Specification parameters
1. Working voltage: 6.5 ～ 100VDC
2. Test voltage: 6.5 ~ 100VDC
3. Rated power: 20A / 2000W
4. Measurement accuracy: 1.0 level
B. Display and key
1、 Display interface
Display by the large screen LCD LCD display voltage, current, power, electricity parameters.
2、 Display format
1. Power: test range 0 ~ 2kW
The display format is 0.0 ~ 999.9w within 1kW;
The display format above 1kW is 1000 ~ 2000W.
2. Power: test range 0 ~ 9999kwh
The display format is 0 ~ 9999wh within 10kwh;
The display format above 10kwh is 10 ~ 9999kwh;
3. Voltage: test range: 6.5 ~ 100V
Display format 6.50 ~ 99.99
4. Current: test range 0 ~ 20A
The display format is 0.00 ~ 20.00.
3、 Key
1. Backlight control
The backlight can be turned on or off by pressing the key for a short time, and the backlight status will be saved automatically after power failure.
2. Clearing the electric quantity
Step 1: press and hold the key until the "CLR" character is displayed in the power display area, and then release the key;
Step 2: at this time, the power flicker indicates that it is in the state of power clearing. If you press the key again, the power data will be cleared and will exit the zero flashing state;
Step 3: if there is no key operation within 5 seconds, it means that the power data is not cleared and exits the reset state.
3. Setting of voltage alarm value
Step 1: press and hold the key until the "set" character is displayed in the power display area, and then release the key;
At this time, when the low-voltage value is higher than 3 seconds, the current low-voltage alarm value can be automatically displayed by pressing the low-voltage alarm key for 3 seconds. When the current low-voltage value is not set, it will automatically display the alarm value from the current low-voltage value of + 1 bit The range is 6.5-99.9v;
Step 3: after setting, press and hold the key until the "pass" character is displayed on the screen, which indicates that the setting is successful and automatically exits the setting state.
C. Precautions
1. This module is suitable for indoor use, not for outdoor use.
2. The load should not exceed the rated voltage and current.
3. The wiring sequence should not be wrong.
