HART375C/E Handheld deviceDetailed product description：

The HART375C handheld communicator is a handheld communicator that supports HART protocol devices. It can configure, manage, and maintain all devices that comply with the HART protocol. The domestically produced HART375C handheld controller can easily connect to the 4-20mA HART protocol instrument current circuit, communicate with the HART protocol instrument, configure the set parameters of the HART instrument (such as range upper and lower limits, etc.), read the detection and set values of the instrument, and diagnose and maintain the instrument, etc. This handheld device supports the first master device of HART protocol (such as HART bridge), as well as point-to-point and multi-point communication methods of HART protocol.

Features of HART375C Handheld Operator
Support delayed shutdown: Press the key I/O button for more than one second to turn on or off the power of the handheld device
Output HART amplitude automatic control: In noisy environments, the output amplitude of the HART signal will automatically double
New active bus noise processing circuit for better communication performance
Longer working hours: Three Nanfu No. 5 batteries can work continuously for 150-200 hours and have a battery level indicator
1% battery level measurement for more accurate display
Add emerald green backlight for clearer display (suitable for operation in dim/nighttime environments)
Users can actively turn off the backlight (by holding down the conversion key in the bottom right corner for more than 1 second, the backlight can be turned off or on)
Fully functional support for dozens of instruments: SIMENS PDS, P300, LR200 radar level gauge, Rosemount 1151, 3051, 644, 248, 2051, SIMENS DSIII, PS2, SIPART PS2 valve positioner, Yokokawa EJA, EJAX, ABB, FOXBORO, etc. (Instrument support may vary between Chinese and English)
Support shortcut keys: Users can directly access related functions by using numeric shortcut keys
Improved new shell design with more international product features
Optional Chinese and English interfaces

d) HART interface communication distance<1500m e) HART communication interface has anti EMI measures f) HART communication interface has amplitude automatic multiplication function
3. PC interface section
The PC interface part needs to be connected to the PC serial port through a level converter, which is used to upgrade the instrument library.
4. Power consumption index
Power consumption: 4.5VDC, 19.8mA (working state),
5. The use of batteries
Power supply: Three No. 5 (SIZE AA) alkaline batteries or nickel hydrogen rechargeable batteries.
Continuous working time: When using alkaline batteries, the typical value is 150 hours. When using a 2000mAH rechargeable battery, the typical value is 100 hours.
6. Environmental temperature requirements
Working temperature range: 0 ℃~+50 ℃ Storage temperature range: -20 ℃~+55 ℃
LCD display screen
The LCD screen displays 8 lines by 21 characters and can show 4 lines of Chinese characters.
When the ambient temperature is too low, the response speed of the LCD display will slow down, which is a normal phenomenon; Due to the automatic temperature compensation circuit of this device, the LCD display still has good contrast even in high ambient temperatures, which is convenient for your usage needs in different environments.
