panel

The middle of the front panel is240×64Dot matrix LCD display screen, on the right side“Printing, locking4L/3L、●、 ＞, ＜∨、∧Set up”There are a total of nine keys, including the power switch and power indicator light on the lower left side.
The display modes are respectively no-load test and short-circuit test, and the switch status is no-load test“∧”Key implementation for display mode conversion.
The display mode of the no-load test is as follows:

The display mode of the short-circuit test is as follows:

To complete various functional operations, the key functions are as follows:

4L/3L key: Press the key continuously, and the two indicator lights on the key will turn on4L/3LCycle lighting, when4LThe indicator light is on, and the instrument panel is in the“Three watt method”Measurement: When3LThe indicator light is on, and the instrument panel is in the“Two watt method”Measurement.
Lock button: Press this button, the corresponding indicator light will turn on, indicating that the instrument is in a locked state. Press this button again, the indicator light will turn off, the instrument will exit the lock, and the normal measurement state will be restored.
Print button: Press this button to display all instantaneous measurement values in a fixed format on the instrument. (The printer must be in a connected state)
Setting∧(Increase in numbers)∨(Number reduction),<(flashing position to the right),>(flashing position to the left)●Place six keys (decimal point) to complete the parameter setting function. Before testing, it is necessary to correctly set the parameters. Press the setting button to display:

Ku: represents voltage multiplier
Ki: represents current rate
Uo: represents the rated voltage of high voltage
T: Representing copper or aluminum materials
t: Indicate temperature
Se: represents the rated capacity
U: Indicates the rated voltage of low voltage.
Press the power switch, and the power indicator light will turn on.
