Product DescriptionProduct DescriptionBuilt - in Diagnostic CapabilitiesThe 691HT22E000000 comes with a comprehensive set of built - in diagnostic tools. When connected to a field device, it can quickly detect and report any issues related to the device's operation. For example, it can identify problems such as sensor failures, communication errors, or incorrect configuration settings. The diagnostic information is presented in a clear and understandable format on the LCD display.In the case of a sensor failure, the communicator may display an error code along with a brief description of the problem, such as "Sensor Open Circuit" or "Sensor Drift Detected." This allows maintenance personnel to quickly identify the root cause of the problem and take appropriate corrective actions. The diagnostic capabilities also extend to communication - related issues. If there is a problem with the HART communication link, the communicator can provide information about the nature of the communication error, such as a CRC error or a timeout error.Historical Data LoggingSome models of the 691HT22E000000 may offer an optional historical data logging feature. This feature allows the communicator to record important data from field devices over a period of time. For example, it can log the measured values of a pressure transmitter at regular intervals, along with any associated diagnostic information or events.The historical data can be invaluable for analyzing the performance of field devices over time. Maintenance engineers can use this data to identify trends, such as gradual changes in sensor readings that may indicate impending failures. By studying the historical data, they can also evaluate the effectiveness of maintenance actions and make more informed decisions about future maintenance schedules and strategies.Precise Sensor TrimmingSensor trimming is a crucial aspect of ensuring accurate measurement in field devices. The 691HT22E000000 enables precise sensor trimming for connected devices. When performing sensor trimming, the communicator allows the operator to input values with a high degree of precision. It accepts the first five digits of the input, and small differences, of the order of 0.003% of the upper - range value (URV), on the reading are tolerated.The process of trimming the high and low values of a sensor is straightforward. By pressing the appropriate function keys, the operator can enter the desired values. The communicator then sends these values to the transmitter, and a blinking "t" appears in the upper - right corner of the display, indicating that the communication is in progress. If the entered values are too close to zero or within the minimum span, the operation will abort, and an error message will be displayed, preventing incorrect settings.SpecificationModel691HTTypeHandheld Microprocessor-based CommunicatorCompatibilityHART, FOUNDATION Fieldbus, PROFIBUS PADisplayBacklit LCD (128 × 64 pixels)Keypad16-button tactile keypadPower Supply4 × AA Alkaline Batteries (or rechargeable NiMH)Battery LifeUp to 20 hours (typical use)Operating Temperature–4°F to 140°F (–20°C to 60°C)Storage Temperature–40°F to 158°F (–40°C to 70°C)Humidity Range0–95% RH (non-condensing)Communication PortsInfrared (IR), USB (for updates/data transfer)Supported ProtocolsHART (5/7), FOUNDATION Fieldbus, PROFIBUS PADevice ConfigurationFull parameter configuration, calibration, diagnosticsSoftware UpdatesVia USB or online downloadEnclosure RatingIP54 (dust and splash resistant)Languages SupportedMultiple (English, German, French, Spanish, etc.)WeightApprox. 1.1 lb (0.5 kg) with batteriesCertificationsATEX, IECEx, FM, CSA (for hazardous areas)Company ProfileKerui (Weifang) Automation Equipment Co., Ltd. specializes in industrial automation instrument development, production and sales, technical services, and supportingequipment supply of specialized companies.
