Second, the instrument wiring method

Please refer to the random wiring diagram

Third, the instrument settings

11) Keyboard keys:

: Moves the menu item up or up.

: Moves down the menu item or The value is decreasing.

Menu : Edit the menu or shift the value to the right.

: Go back to the previous menu, go back and save the settings in the parameter settings.

2) Indicators:

'k': Thousand units, the real value of a thousand times the value shown.

'M': Trillion units, the true value of a trillion times the value shown.

'AH ': Upper limit alarm, light shows red.

'AL ': Lower limit alarm, the light shows green.

2Display the operating instructions

After power-on, CHSH 8.8.8.8 is displayed and the test state is entered.

3.Set up the operating instructions

The password can be entered into the select programming mode, after entering the programming mode, you can modify the parameters of the instrument settings.Key operation, the keypad can be used to display the parameters of the parameters, the program mode can be edited, If not on the instrument operation, 1 minute after the automatic back to the measurement state

1)Operating mode

Under normal circumstances, the instrument is in the normal display of the power value of the working state Menu Key to enter the view state, you can view the parameters of the instrument.

Press Menu Key, appears PUT, enter the correct password, you can enter the programming mode. The factory default password value is 8888

2)Displays the character description

Fourth, the use of pre-note

1.Working environment temperature is -25 ~ +40 ℃;

2.Before use, please check that the terminals are connected correctly and firmly.

3.Communication format and baud rate are factory defaults e, 8,1,4800;

4.No standard equipment and non-professionals should not be adjusted;

5. CT The current in the circuit wiring terminal screws must be tightened to ensure reliable lead contact to avoid accidents;

6When the input nominal current exceeds AC 5A, the current transformer CT (secondary current 5A) shall be furnished.
