What does the LCD Hall Cullen Current Voltage Power Electric Energy Meter measure?

This meter can be used to measure percentage and AH of remaining capacity, DC positive and negative bidirectional current, DC voltage, DC positive and negative power, DC positive and negative bidirectional accumulated electric energy.

What alarm function does the meter have?

It will alarm and flash to draw your attention when the real voltage is higher or lower than preset alarm voltage and real current is higher than preset current. The preset voltage and current could be adjusted as you need. It will also alarm and flash to draw your attention when the remaining capacity of battery is low and the battery icon will keep flashing that means you need to charge for your device.

What other functions does the meter have?

• It will automatically fill the capacity of the battery when it is full voltage.
• It has the function of clearing current and accumulated electric energy data and the function of storing data when power-down.
• Capacity of battery and accumulated electric energy will be saved automatically when power down.

How to control backlight?

When standby display, press• key to turn on or turn off the backlight. Backlight mode will be save when power-down.

How to clear current?

When standby display, to keep pressing• key will clear current to zero if no load is connected. (Note: if you don’t clear current when no load connected, it will be inaccurate).

How to clear electric energy?

When standby display, to keep pressing ■ key and release the key will clear positive and negative bidirectional accumulated electric energy.

How to set parameters?

When standby display, press ■ key to switch menu in order.

• (1) "AH XXX.x’’ Setting Menu for rated capacity of battery
• (2) "FU XXX.x’’ Setting Menu for fulfilling voltage when full charged
• (3) “HU XXX.X” Setting Menu for over-voltage alarming
• (4) “LU XXX.X” Setting Menu for low-voltage alarming
• (5) “HA XXX.X” Setting Menu for over-current alarming

How to set the rated capacity of battery?

(1) When standby, press ■ key to switch to menu “AH XXX.X” (2) The first digit on menu parameter will keep flashing, at this time, pressing• key, the digit will plus 1. After finishing setting this digit, the next digit will automatically flash when no any action in 5s. At this moment, pressing• key, the digit will plus 1,too. In this way, you will finish setting 4 digits. (3) Keeping pressing ■ key, then release the key, the set parameters will be stored, at this time, menu will flash twice that means you have set successfully.

Eg. If you want to set battery’s rated capacity as 20AH, just set the menu parameter as AH 020.0, then keep pressing the ■ key, finally release the key, you can make it stored successfully.

How to set automatically filling voltage when full charged?

When standby, press ■ key to switch to menu "FU XXX.x’’, press• key to set parameters and keep pressing to save set parameters. (Note: It is suggested to set the voltage as the voltage when full charged.) By using the same setting method to set the value of over­ voltage alarming, low voltage alarming and over current alarming.

(Note: HU XXX.X LU XXX.X HAXXX.X, if the 3 parameters display as 000.0, that means the alarming function is off, factory setting is off. )

What are the wiring instructions when the measured voltage is DC 5-90V?

This meter can be connected with two-wire system connection. Making the red wire and yellow wire in parallel and then connect it to the positive of battery.

What are the wiring instructions when the measured voltage is over DC 5-90V?

This meter must be connected with three-wire system connection. A separate power supply is needed for this meter.

What is the correct wiring method?

Cullen meter display positive current when discharging and display negative current when charging. If not, that means you connected the transformer in wrong direction.

What do I need to do with a newly installed Cullen meter?

Newly installed Cullen meter need to clear current when no load connected. When the newly installed Cullen meter has been set battery capacity and automatically filling the voltage when fully charged, you need to make battery fully charged again, then it can display remaining capacity.
