Multi-function Volt-ammeter 1.8 Inch LCD Display Voltage

It is a basic multi-function instrument that can display various kinds of parameters such as display the voltage, current, , capacity, energy, temperature, running time, and other physical parameters in real time. Over-voltage, under-voltage, over-current and over-temperature protections can be achieved through reserved relay interfaces. And the meter uses 1.8-inch color LCD as display, display data more comprehensive and clear, easy to observe. This meter is perfect for applications that require monitoring of the output voltage and current as well as charge and discharge batteries.



Features:

Bidirectional current detection, for detecting charge and discharge users can easily detect bidirectional current properties, no need to change the direction of the connection.

off memory function, after off, the number of AH and WH before off can be memorized, convenient for observation and measurement.

Time and AH data clearing function, do not affect the measurement later.

The percentage of AH can be set without affecting direct discharge measurement.

Voltage, current, AH, WH, time, , simultaneously displayed, comprehensive and clear information display.

With output disconnect function key, flexible on or off output.

With over-voltage, over-current, over-temperature and other extended-protection functions.

It can be calibrated online, enabling customers to promptly correct the error.

In the crystal display can be closed when necessary, reduce consumption.



Function Introduction:

1. BAT" battery capacity value setting, this parameter is to set the battery measured total capacity.

2. "BPC" battery remaining capacity percentage, can be set according to the value of the remaining battery AH.

3. "OVP" set over-voltage protections value, if the OVP value is set, when the actual measured voltage value is greater than the set value, it will prompt over-voltage, and cut off the relay(self-provisioned).

4. "LVP" set overvoltage protections value, if you set the LVP value, when the actual measurement of voltage is less than the set value, it will prompt the undervoltage, and cut off the relay(self-provisioned).

5. "NCP" sets the charge overcurrent protections value. If the NCP value is set, when the actual measured -current value is greater than the set value, it will prompt overcurrent and cut off the relay(self-provisioned).

6. "OCP" sets the discharge overcurrent protections value. If the OCP value is set, when the actual measured discharge current value is greater than the set value, an overcurrent will be prompted and the relay(self-provisioned) will be cut.

7. “OTP” sets the over-temperature protections value. If the OTP value is set, when the actual measured temperature value is greater than the set value, the over temperature will be prompted and the relay(self-provisioned) will be cut off.

8. "ADS" communication address code setting.In multi-machine communication, multi-machine communication is achieved by setting the address code.

9. "TTL" instrument powers up the output state of the default relay, normally open or normally closed.

10. "CLR" no-load current correction function, if the actual load current is zero.
