If you need only the CT, please check this: >>> Here Many buyers are response: Why test data is wrong? Voltage * Current = Power, But power is less than the actual test voltage * Current, Why is that? Answer: There are three types of power: Active Power (P represents / unit W) Reactive power (Q represents / unit Var) Apparent power (S represents / unit VA) Here that We only talk about Active Power, others please google it: P = U * I * cosφ, cosφ it represents the power factor, purely resistive load (Such as incandescent, heater, etc.) the power factor is generally close to 1,Between the inductive and capacitive load load power factor 0-1. So purely resistive load test time, P is substantially equal to or close to U * I. When Inductive or capacitive load test (Such as refrigerators, washing machines, televisions, computers, etc.) P U*I, As for how much to keep the power factor related to the specific, Different for each appliance power factor. Note: 1. This module is suitable for indoor, not outdoor use. 2. applied load can not exceed the rated power. 3. The wiring order can not be wrong.

Voltage * Current = Power, But power is less than the actual test voltage * Current, Why is that?   Answer: There are three types of power: Active Power (P represents / unit W) Reactive power (Q represents / unit Var) Apparent power (S represents / unit VA)   Here that We only talk about Active Power, others please google it:   P = U * I * cosφ, cosφ it represents the power factor, purely resistive load (Such as incandescent, heater, etc.) the power factor is generally close to 1,Between the inductive and capacitive load load power factor 0-1. So purely resistive load test time, P is substantially equal to or close to U * I. When Inductive or capacitive load test (Such as refrigerators, washing machines, televisions, computers, etc.) P Note: 1. This module is suitable for indoor, not outdoor use. 2. applied load can not exceed the rated power. 3. The wiring order can not be wrong.   Package included: 1 x Power monitor module

I have not film tested this camera. I have checked the mechanics and appears to fire accurately. A battery would be needed to test the meter. In the worst-case scenario, should the meter not be working, there are a host of free cell phone apps that can be used for light metering. Having said all that, if the camera is to be used professionally, a service is always recommended for ultimate perfection. Please feel free to contact me for technician details depending on your location.

Features:   Electrical parameter measurement function (voltage, current, active power, energy). Running time function(records the accumulated operating time of load). Backlight and overload warning function(backlight flashing to alarm when overload). Power warning threshold preset function(you can set your own power warning threshold). Power-down data storage function and long press button for energy and running time reset function.(store the accumulated energy, running time, display items, the state of backlight on/off). STN whole viewing angle LCD(display voltage, current, active power/energy at the same time)   Specifications:   Operating frequency: 45-65Hz Rated power: 22KW Working voltage: 80-260VAC Testing voltage: 80-260VAC Testing current: 0-100A Testing energy: 0-9999kWh Dimensions: about 62 x 52 x 24mm   Test Range and Display format: 1.Power: test range: 0~22kW 1kW~10kW, display: 1000~9999W > 10kW, display: 10.0~22.0kW 2.Energy: test range: 0~9999kWh >10kWh, display: 10~9999kWh 3.Voltage: test range: 80~260V(single-phase) Display: 80~260V 4.Current: test range: 0~100A Display: 0.00~99.99A   Precautions:   1. Please make sure the AC input is Pure Sine Wave.(Municipal electric power is pure sine wave). Please don't use the meter to measure AC power converterd from a DC-AC inverter UNLESS you can make sure the output from your DC-AC inverter is Pure Sine Wave. This is very importatnt. 2. Applied load should not exceed the rated power. 3. Wiring order can not be wrong. 4.
