Dwyer Instruments ASG Generator
The Dwyer Instruments ASG Analog Signal Generator is a critical diagnostic tool for any HVACR contractor or building automation technician. This handheld, pocket-sized device simplifies the troubleshooting of 0-10Vdc and 0-20mA circuits, providing a reliable source for calibrating transmitters, transducers, and actuators in the field. Built for efficiency, the ASG features an LED bar graph that gives you immediate visual confirmation of the signal level, making it easy to monitor performance even in poorly lit mechanical rooms. Unlike basic testers, this unit includes a programmable ramp function that allows for continuous cycling between user-defined endpoints at specific time intervals, which is essential for verifying the full range of motion for modulating valves and dampers.
Engineered for versatile power options, the ASG Generator runs on a 9V battery or the included 120Vac power supply, ensuring you stay operational during long shifts. The selectable auto shut-off feature helps preserve battery life, while the 300-ohm current impedance and 1000-ohm voltage impedance ratings provide the precision needed for sensitive control loops. With separate output jacks for source and 2-wire transmitter simulation, it integrates seamlessly into existing analog signal validation workflows.
Key Benefits for Technicians:- High-Visibility Diagnostics: The integrated Bar Graph LED allows for quick, at-a-glance signal monitoring in dark or cramped spaces.
- Automated Testing: Use the Ramp Function to automate the stroking of valves and dampers without manual incremental adjustments.
- Dual-Power Flexibility: Switch between battery power for mobility and 120Vac for extended bench testing or stationary calibration.
- Battery Conservation: Selectable Auto Shut Off prevents accidental drainage, extending the life of your 9-volt cells.
- Broad Compatibility: Supports standard 0 to 20mA and 0-10Vdc output ranges used in modern Building Automation Systems (BAS).
How do I test a 4-20mA loop with the ASG?
The ASG provides a 0 to 20mA source. To test a standard 4-20mA loop, simply set the unit to the current scale and use the buttons to verify 4mA for the low end and 20mA for the high end. The mA Overload LED will alert you if the circuit resistance exceeds 300 ohms or if there is an open circuit.
Can the ramp interval be customized?
Yes, the ramp function timing is variable. Technicians can set the interval increments using the mA scale to represent seconds (e.g., 10mA corresponds to 10 seconds), allowing for precise travel-time testing of motor actuators.
Does it support loop-powered circuits?
The unit includes a dedicated 'mA Two-Wire' output specifically designed for loop-powered (externally powered) circuits, in addition to its internal mA source output.
