Products overview:
At the scene of the HART475 comHand-held com is to support the HART protocol equipment, mainly used in industrial field of HART intelligent instrument for configuration, management, maintenance, adjustment and monitoring of operation instrument in the process of process variables, equivalent to that of ROSEMOUT - 375 hand operator, functions are basically the same, and the low price and good compatibility.
Second, the measuring principle:
At the scene of the HART475 comIs a portable terminal, it with the HART communication protocol of the instrument are used together, to set, change and display, it can monitor the input/output value and the diagnosis.Set the constant current output and zero.
When the system start or maintain operations, as long as the take type HART475 HART communication apparatus in 4 ~ 20 ma communication signal lines, can be used.
Applications:
1, fully supports all accord with a standard HART communication;
2, rosemount 1151, 3051 smart pressure transmitter (supporting the new version);
3, yokogawa EJA smart pressure transmitter (supporting the new version);
4, 1151, 3151, intelligent pressure transmitter;
5, Mr Jerry buss CDS - 3151 intelligent pressure transmitter;
6, Siemens intelligent pressure transmitter;
7, LS LanLian Ⅲ intelligent pressure transmitter;
8, Russia METRAN - 49, 100 intelligent pressure transmitter.
Four, hand function:
1, HART intelligent device for production testing, the diagnosis and inspection, etc.;
2, to HART intelligent configuration in the operation of the equipment at the scene, calibration, diagnosis, maintenance, monitoring, etc.;
3, get HART instrument manufacturers information;
4, understanding HART instrument's working state and fault letter;
5, read the meter output current and process variables;
6, obtain the parameters of the sensor and the output value.
Five, the main features:
1, the online monitoring and communication
Intelligent hand operator during the communication, not break 4 ~ 20 ma DC modulation signal;
2, can be Shared with the HART communication protocol of the instrument
Can type HART275 HART communication apparatus with the HART communication protocol of all instruments used together;
3, easy to operate
Large display screen (4 rows, each row 18 characters), in Chinese, according to the user see the be clear at a glance, convenient setting and change;
4, the information from the diagnosis/protection function
Since the inspection function;
Format the password protection;
Low voltage alarm display.
Six, the technical parameters:
The microprocessor 80 MHZ;
Built-in memory of 32 m;
System card 128 m or more working environment - 10 to 50 degrees Celsius;
Random access memory of 32 m protective IP51 (positive);
Extension module 32 m seismic 1 m to the ground to the concrete ground there is no problem;
Weight about 0.9 KG, including battery humidity 0 ~ 95% (no lon);
According to 1/4 VGA (240 * 320 pixels) storage - 20 to 55 degrees Celsius (with battery);
- 20 ~ 60 degrees Celsius (without battery);
25 keyboard keys, four key operation, 12 letters, four shoulders, four function keys and open the key;
Rechargeable nimh batteries, can use 10 hours, 85 ~ 240 vac charge;
Shape size: 228 mm x 98 mm x 60 mm.
Seven, the hands of the specifications of the operator:
1, HART protocol communication standard;
2, fully supports all mainstream instrument HART command;
3, working temperature range: 0 ℃ to 50 ℃.
4, hand value is greater than 0.5 Kg.
Eight, reliability:
HART field communicator average service life time not less than 12 years, the independent power average trouble-free operation time not less than 20000 hours, hand operator battery can work continuously time not less than eight hours.
Nine, scope of supply includes:
1, with a rechargeable battery and cable HART hand;
2, the battery charger;
3, carrying bag.
Ten, use notice:

Note 1: HART hand operator
Full range format wrong operation and remedies:
1, the input pressure value and pressure values are not equal.
2, input negative pressure, no plus negative number.
3 do formatting, no input pressure value.
When you meet the above error format must to do full range
Note 2: interpolation type wrong operation and remedies:
1, the input pressure value and pressure values are not equal.For example: want to do in 20 kpa point interpolation, external and 20 kpa pressure, but the input is 200 pa.
Remedy: to do full range format
2, when the external pressure is not enough for interpolation.For example: want to do in 20 kpa point interpolation, external only added to the 10 kpa pressure, input is 20000 pa.
Remedy: select menu: main characteristic format menu??Interpolation, add the external pressure to 20 kpa, enter 20000 pa, press the right arrow.
Note 3: sensors fine-tuning wrong operation and remedies:
1, high low-end fine-tuning, the input pressure value and the actual external pressure are not equal.
For example: high-end fine-tuning, external 120 kpa pressure, but the input is 120 pa.
Remedy: new high-end fine-tuning, external to add 120 kpa pressure, enter 120 kpa.

Quality assurance and after-sales service:
Intelligent HART hand operator products quality assurance period for 12 months, life-long maintenance.Warranty period for the damage, free maintenance, more than warranty, maintenance fee and shipping fee only.To new users first use, generally by the menu function prompts the operation, there are technical difficulties, please call the company technical department to give answers. Company can send engineers to the scene to guide if necessary.
