AUTO Step Menu |
(please refer to page 6 for the specific description of automatic output) Press the "IN" key to enter the setting menu: 1. Automatic mode, quickly switch the mode through the ‘←’ and ‘→’ keys 2. 2. Maximum value: press the "IN key" to enter the editing mode, and confirm that the editor presses the "IN key" once 3. Minimum value: "IN key" enter the editing mode, and confirm the editing by pressing "IN key" once 4. Delay: press "IN key"; enter the editing mode, and confirm that the editing is pressing "IN key" once 5. Step value: Press IN key "to enter the editing mode, and confirm the editing by pressing IN key once" |
Keep |
Press "IN key" to switch on/off (used to maintain the set output signal value) |

① : type of measurement signal
It works repeatedly from the minimum signal value to the maximum value and then from the maximum value to the minimum value output
Rise from the minimum signal value to the maximum value, and then directly change from the maximum value to the minimum value output, so work repeatedly
After pressing the automatic output key, the signal will be output at the maximum value, and then it will be output from the maximum value to the minimum value, so it works repeatedly-6-

Valve commissioning |
|
|---|---|
② : bottom half screen |
|
Pneumatic positioner |
Commissioning pneumatic valve positioner:
1. Press the "IN" key to switch the upper screen measurement to distribution measurement 2. Press "OUT" to switch the output of the lower half screen to current output 3. Refer to the wiring diagram of the left pneumatic positioner for connection 4. Modify the current value to be more than 4mA and check whether the valve works 5. If the lower half of the screen changes between current output and open circuit, the wiring may be incorrect |
 Electric actuator |
Commissioning electric actuator:
1. Press the "IN key" to switch the upper screen measurement to current measurement 2. Press "OUT key" to switch the output of the lower half screen to current output 3. Refer to the wiring diagram of the left pneumatic positioner for connection. Note that only three wires are required 4. Modify the current value to be more than 4mA and check whether the valve works 5. If the lower half of the screen changes between current output and open circuit, the wiring may be incorrect |

Battery |
|
|---|---|
This product can use two kinds of batteriesLithium battery:
A 2500ma lithium battery is built into the product. For the health of the battery, if you don’t use it for a long time, please charge it to about 80% and try not to fill it up. When the battery is at the lowest level, please charge it immediately, otherwise it will damage the battery or cause battery damage
AA No.5 battery: after removing the lithium battery, three 1.5V ordinary alkaline batteries can be installed. If the battery is exhausted, please take out the battery in time to avoid damaging the product due to liquid leakage |
