7.7Parameter calibration interface
This interface is for calibration of instrument parameters. In order to ensure the accuracy of the instrument, this interface is not open to the user.
8、Attention
The instrument must have a good grounding in use
Check the temperature of 23 + 1 degrees.
To ensure the accuracy of the instrument, please preheat 30 minutes before use.
Attention should be paid to the proper limits of the objects to be measured.
instrument terminal output as standard source, the terminal can not access any other power supply.
tandard power output, you must first select the output voltage and phase, power loss
Out of the maximum 120% of the theoretical value.
In this equipment and other equipment shall disconnect all power devices connected before communication, however electrical connections cause damage to the equipment.
When DC output 5A 25A, please raise the current to 100%, preheat five to ten minutes.
