Key use method:
The instrument is designed with single key and can realize various operations.
A: In the normal interface, the length is 3 seconds into the adjustment state. The selected adjustment items will flicker. In this state, click the button to switch back and forth in the adjustment items. When selected: real time electricity, accumulating electricity, accumulating power, double click the button to realize the zero operation. When the alarm switch is selected, the channel switches, double click switch when the channel switches. When selected: upper and lower values, double click to enter data adjustment. In adjustment state, press 3 seconds to exit.
B: under normal interface, double click the button (2 times in short time), enter the calibration interface. It can calibrate the voltage, current, and zero point. The adjustment range is +/-50%. When the parameters flicker, double click, enter the position adjustment (underline below the corresponding number), click the cycle to change the number, double click, change the adjustment position, and press the exit boundary.
Supplement: this interface can also set alarm output mode. This function is very practical.
OUT:TUNR [alarm level changes with alarm status changes]
OUT:HOLD [alarm level lock, when the alarm occurs, output high level, even if the alarm conditions disappear, the output level remains, until a key to restore the low level]
Wiring method:
There are two sets of lines
Three of the finer A: groups,
Two thick B: group,
Group A:
black wire: power supply negative pole
Red wire: power supply positive. Warning: the maximum can only be connected to 28V, more than damage
Yellow wire: connected to the positive electrode needed to measure voltage
Group B:
black wire: the negative electrode of the tested power supply
Red wire: the negative electrode of the load to be measured. Warning: not connected to the power supply positive pole, otherwise burned
