Industry Applications
With HART and Foundation Fieldbus applications, you can configure and test valves inline, reducing downtime. The wireless capability lets you synchronize field data with AMS Device Manager automatically, improving data accuracy. The IP54 enclosure and shock-tested design (survives a 1-meter drop onto concrete) make it suitable for harsh field environments.

Installation & Setup Guidance
Before first use, fully charge the rechargeable Li-Ion power module. The device is intrinsically safe, so you can connect it to live loops without special permits. Use the touchscreen to navigate the Windows Embedded Compact 2013 interface. For wireless synchronization, ensure the device is within range of your AMS Device Manager network. Follow standard safety procedures when connecting to field wiring.
Maintenance & Reliability
Inspect the touchscreen and enclosure regularly for damage. Keep the device clean and dry. The battery provides 8+ hours of typical use; recharge after each shift. The device is designed to survive a 1-meter drop onto concrete, but avoid unnecessary impacts. Operating temperature range is -4 to 122°F, so avoid prolonged exposure outside this range.
