HPC79A Process Signal Generator
Output Basic Characteristics
+ Output basic accuracy: 0.05%, output display with 5 digits.
+ Output functions: DC voltage, DC current, resistance, frequency, thermocouple, RTD (Resistance Temperature Detectors), and SIMULATE function to emulate transmitters.
+ Dual display for DC current output: Simultaneously shows mA and Percentage values;supports manual stepping (25%/100%), auto-stepping, and auto-ramp current output.
+ Built-in 24V loop power supply.
Measurement Basic Characteristics
+ Measurement functions: AC/DC voltage, resistance, capacitance, AC/DC current, continuity, diode testing, frequency, thermocouple, and RTD.
+ High precision: 0.05% basic accuracy with 55,000 counts display.
+ Measurement rate: Fast mode (20 readings/sec), slow mode (5 readings/sec).
+ Manual or auto range option, with hold function.
+ Relative value measurement (REL_%)
+ Low-pass filtering function (VFC) enables accurate voltage measurement in variable-frequency drives or other noisy environments.
+ Dual functionality: Simultaneously powers 24V loops and measures loop current.
+ Built-in optional 250Ω HART loop resistor for easy use with HART communication devices, eliminating the need for an external load resistor.
+ Built-in temperature sensor with automatic cold-junction compensation (℃/℉display).
+ Manual cold-junction compensation option.
Other Features
+ IP65-rated dust and water resistance.
+ CAT IV 600V and CAT III 1000V safety standards.
