EN4000A-P Small-sized Paperless Recorder（OLED Display）

The EN4000A-P series small-sized paperless recorder is designed & made by ENVADA U.K. The instrument display has multiple features including high luminescence, high resolution, wide angle of vision, etc based upon the advanced OLED technology used.

EN4000A-P can measure, display and record 1-4 way input signals including standard current, standard voltage, standard thermal resistors, the standard thermocouples, frequency, etc. It can also carry out many functions including the data acquisition, the data process, the data display, the data remote transmission, the data record, the USB access, etc and is very suited to use in a compact working place where many functions are assembled.

	Function Characteristics

Ease of use and rapid operation:
An EN4000A-P series instrument has 6 control keys, through which all setup and operating functions can be carried out. In setup mode, the instrument will provide hints/help based that can prompt the user as to how to carry out the setup procedure appropriately.

Multiple display functions:
An OLED screen with high luminescence, high resolution and wide angle of vision is used. The measurements, engineering units, working state, system time, setting parameters, hints, etc can all be displayed on the screen. There are many powerful display functions including real-time curve display, bar chart display, multi-channel digital data display, graphical historical data display(recall display), the large digit display, etc are available to indicate the operating state of the device in place of work.

Powerful signal process function:
Every channel of EN4000A-P can receive signals from a standard current, a standard voltage, a standard thermal resistor, a standard thermocouple, a frequency source etc. Transfer of the input signal can be easily defined through a simple setup operation. The transfer of a frequency signal or other analogue signal is equally easy to define. Each channel can also be provided with an independent power supply of 24VDC.

Flexible alarm function:
There are multiple independent alarm points available. The 4-level alarm (high limit of high limit, high limit, low limit, low limit of low limit) can be set for each channel. The user can designate all alarm outputs. Each alarm points can alternatively use only one output. The states of 4-level alarm of the requested channel can be overlaid on the measurement display.

Complete auxiliary function:
There is an optional USB interface so as to make the data transmission and storage simple and fast. The data can be displayed, analyzed, counted and printed through the data management software provided by ENVADA. The instrument can provide a multi-channel current transducer output function so there are programmable current output options of 4-20mA, 0-20mA and 0-10mA available.Data can also be read directly through an RS485 communication interface based on a common MODBUS protocol so a real-time monitoring system can be easily established, and can directly connect with a printer to print any messages needed.
