• Cable Gland: Compatible with 0.114 to 0.250 inches (2.9 to 6.4 mm) diameter cable.

Ensure all electrical connections comply with local electrical codes.

4.3 Pressure Connections

Connect the pressure lines to the appropriate ports on the gauge. Ensure connections are secure and leak-free. The gauge is designed for use with air and non-combustible, compatible gases.

5. Operating Instructions

The DM-1000 features a user-friendly interface with four buttons for operation.

5.1 Powering On/Off

Connect the device to a suitable power source. The unit will power on automatically and display the current pressure reading.

5.2 Display Units

The 4-digit LCD can display readings in various common English and metric units. Refer to the full product specifications or consult the factory for a complete list of supported units and how to cycle through them.

5.3 Zero and Span Calibration

The DM-1000 allows for simplified digital push-button zero and span calibration. This feature helps maintain accuracy over time.

1. Zero Adjustment: With no pressure applied (or at a known zero reference), press the designated zero button (e.g., 'MENU' or 'E' in combination with others, refer to on-screen prompts or detailed product sheet).
2. Span Adjustment: Apply a known full-scale pressure (or a specific calibration pressure) and use the span adjustment function (e.g., 'MENU' or 'E' in combination with others) to match the display to the applied pressure.

Note: For precise calibration procedures, it is recommended to consult the detailed product manual available from Dwyer Instruments or contact their technical support.

6. Maintenance

The Dwyer DigiMag DM-1000 is designed for minimal maintenance. Regular checks ensure optimal performance.

• Cleaning: Clean the exterior of the gauge with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Pressure Connections: Periodically inspect pressure connections for leaks or damage.
• Recalibration: Although factory calibrated, periodic recalibration may be necessary depending on application and environmental conditions. Consult Dwyer Instruments for recommended recalibration intervals.
