This multimeter could show 3 measured data at the same time, and you can simply press one button to switch power and energy data. The wiring diagram is on the back of this multimeter for convenient wiring. The meter support overload alarm function, reset energy function, power alarm threshold preset function, etc. Specifications: Rated Power: 22kW Frequency: 45-65Hz Measuring Accuracy: ±1.0% Size: 67 x 57.5 x 24mm / 2.63 x 2.26 x 0.94" Power Test Range: 0~22kW Display Format: 0.0~999.9W when <1kW; 1000~9999W when ≥1kW and <10kW; 10.0~22.0kW when ≥10kW and ≤22kW. Energy Test Range: 0~9999kWh Display Format: 0~9999Wh when <10kWh; 10~9999kWh when ≥10kWh and ≤9999kWh. Automatically back to zero if it is over test range. Current Test Range: 0~100A Display Format: 0.00~99.99A Function: 2. Overloaded alarm as backlight and power flashes if power is over threshold. 3. Power alarm threshold setting. 4. Energy data reset. 5. Data preservation when after power outage. 7. Backlight. Instruction: 1. Backlight: Press "light" button to open or close the backlight(automatic save backlight state after power outage). 2. Energy Reset: Step 1:Press and hold "set" button for more than 3 seconds until the energy display flashes; Step 2:If press "set" button again, reset energy data and exit the reset state; If press "light" button, exit the reset state without resetting energy data; If no button is pressed for 10 seconds, exit the reset state without resetting energy data. 3. Power Alarm Value Reset: Step 1:Press and hold "light" button for more than 3 seconds until the power display flashes; Step 2:When the last digit of power display alarm value flashes, press "set" button to +1, press "light" button to switch to other digit. Alarm value cannot be more than 2.5kW(default is 2.5kW); Step 3:Press and hold "light" button for more than 3 seconds or not press any button for more than 10 seconds to save value and exit. 4. Power/Energy Display Switch: Press "set" button to switch display of power or cumulative energy data(automatically save after power outage). Note: 1. This item can only be used indoors instead of outdoors. 2. The applied load should not exceed the rated power. 3. The wiring cannot be wrong. 4. This meter cannot be used in autotransformer, silicon controlled rectifier circuit or load, otherwise it may be burnt. Package Includes: 1 x Multimeter 1 x Current Transformer(random color) Package List
