Short Operation Manual
1. Pre-Deployment Setup
- Check Calibration: Ensure the level is calibrated (our units come with a 12-month calibration certificate).
- Battery Installation: Insert fresh or fully charged batteries into the compartment, observing polarity.
- Mounting: Attach the level to a stable tripod and adjust the tripod head to level the instrument using the circular bubble.
2. Field Operation
- Power On: Press the power button to start the instrument. The LCD screen will display the main menu.
- Leveling: Use the leveling screws to center the circular bubble and ensure the instrument is level.
- Staff Setup: Place the GeoMax bar-code staff vertically at the target point.
- Measurement: Aim the level at the staff, press the measurement button. The instrument will automatically read the bar code and display the elevation difference in <3 seconds.
- Data Storage: Save measurements to internal memory for later review or transfer to a PC.
3. Post-Use Maintenance
- Cleaning: Wipe the instrument body and lens with a dry, lint-free cloth. Remove any dirt or debris from the objective lens.
- Storage: Place the level in its original hard case, ensuring it is stored in a cool, dry environment away from extreme temperatures and moisture.
- Battery Care: Remove batteries if the instrument will not be used for extended periods to prevent leakage.
